Abstract

Cultural heritage has become a topic of great interest in the recent years.

The widespread of building information modelling (BIM) technology for the

design of new buildings, has raised the attention of many researchers to explore

the possibilities of BIM for the design and the documentation of built heritage

in the restoration process.

The use of Terrestrial Laser Scanner (TLS) and Digital Photogrammetry,

powerful computers and many advanced software has made possible the crea-

tion of complex and complete 3D models of buildings. Today much of the

research is focused in the multidisciplinary use of this big amount of data.

This paper presents the considerations that were made during the research

for integration of building information modelling and some of the main finite

element analysis software in creating a calculation model through different

exporting formats. A proposal is made in order to use the BIM for the docu-

mentation of the crack pattern in the existing buildings and to develop a proce-

dure to export these cracks in the automatically generated calculation model.

The paper also explores the methods used for the implementation of BIM in

cultural heritage and further compares and evaluates the effectiveness of differ-

ent export formats within the interoperability with some of main finite element

software. The study also considers the difficulties and obstacles during the

implementation of the procedures in BIM and the future possibilities of this

technology.

It is common today to study the behaviour of masonry structures in the

light of simplifying assumptions, each of which is not strictly true and must be

hedged with qualifications, and which must in any case be tested in the light of

contradictory experience within a particular building (Heyman, 1995). The

assumptions are that: 1) masonry has no tensile strength and 2) stresses are so

low that masonry has effectively an unlimited compressive strength (average


136

stresses), etc. These assumptions and other are rather conservative but also

stated within the borders of a required accuracy in the masonry structural calcu-

lation results. Today easy-to-use and accurate measurement techniques, ad-

vanced monitoring and diagnostic testing methods, powerful personal com-

puter, but also the high capable software must push the calculations in a new

level of accuracy. The accurate numerical model must represent the building

geometry correctly and allow an accurate determination of the failure mecha-

nisms in the building.

Information technology plays a very important role also in planned conser-

vation. In order to make an attempt, in the analysis of historic buildings, for the

integration of the building information modelling BIM with some of the main

finite element analysis software, in our research Autodesk REVIT was chosen

to explore BIM possibilities, whether for structural analysis two well-known

and widespread software such as CSi SAP2000 v16.0 and Simulia ABAQUS

6.11 were selected.

The first phase of this process is the creation of the geometric model which

could be created with high accuracy with the use of TLS (Terrestrial Laser

Scanning), digital photogrammetry or other methods. The direct result of this

process is a point-cloud. Numerous methods presented in many academic pub-

lications (Fai et al., 2011; Dore, Murphy, 2012; Garagnani, 2012) tend to ap-

proximate the point cloud in continuous surfaces, lines etc., in order to elabo-

rate the preliminary model into a continuous one. Two small models represent-

ing two common and diffused simple historic masonry buildings (Cardani,

2004) (Figg. 1a, 1b) created in the BIM workspace were used for testing the

interoperability between the three chosen software. Results are presented in a

table referring to the export/importing of each element type.

New possibilities of BIM in the structural analysis domain are here dis-

cussed. The crack pattern could be documented in the model and exported to

improve the numerical model. Furthermore some considerations are shown

about the creation of NDT and structural monitoring data control system.

Interoperability

The collaboration between different project actors is indispensable, so the

data can pass from one actor to the other in electronic format (BIM model).

The interoperability between different users can succeed if: a) software from a

unique producer are used; b) software with Open Application Programming

Interface (OAPI) is used; c) suitable export formats are available. The cost of

inadequate interoperability for the AEC industries in the United States has been

PPC Conference 2014

estimated at over $15 billion (Gallaher, 2004). After the full realisation of the

BIM model there is then the necessity to proceed with structural verification of

the modelled building. Revit offers several possibilities with the following ex-

port formats: DWG, DXF, DGN, ACIS (.SAT), IFC, etc.

The formats chosen to be tested are IFC, ACIS (.SAT) and .ERX. All of

them were tested under the algorithm described in Fig. 2.

The IFC (Industry Foundation Classes) is high quality format already af-

firmed in the exchange database (Froese, 2003; Golabchi, Kamat, 2013). Dur-

ing our test the format had a low performance regarding the export of the

model in the structural analysis software (Angjeliu, 2014).

The deficiencies regarded (Fig. 3): a) the location of the elements in the 3D

model (1D beam and columns or 2D shell elements); b) the inability to deal

with opening in walls or slabs (neither of the openings could be imported).

The manual improvement of such model quality to the desired one was

more time consuming than building the entire model from the beginning in the

FEA software.

CSiXRevit is intended as an add-on software, able to create a bi-directional

link of the BIM model with SAP2000 and ETABS through the .erx format. The

export/import of the model is concluded successfully even though in practice

appear small approximations of the dimensions (which are not a problem

unless these changes affect the connection between elements).

The CSiXRevit offers the export not only of the geometrical model (com-

posed of 2D elements) but also of the material properties, section properties,

load assignments, boundary conditions, etc. Care should be taken during the

modelling in the BIM environment to model the walls till their connection with

the transversal ones as separate entities; otherwise problems were verified dur-

ing the export/import procedures. In some cases the curved wall should be

divided in smaller elements in order to approximate the circle in plane ele-

ments. During the tests the typical 3 cell unit model example and the Church

model were exported and imported successfully (Fig. 4).

ACIS SAT is a dedicated format to the 3D models exchange. Between the

chosen software, only Abaqus offers the possibility to use this format. The

format shows difficulties in importing the linear elements (1D). These are im-

ported as 3D elements; whether the other elements (walls, slabs, openings) are

imported correctly. During the export/import process there are no difficulties

(Fig. 5). In standard models, during the creation of the numerical model, the

task of creating the geometry is one the most time-consuming. From this per-


138

spective the results obtained through the use of .sat format can be valuated as

excellent.

The result obtained during the research are summarised in the Tab. 1.

However after the export/import step of the procedure, the user must

make a general check of the imported model, including the geometry, the grid,

the material properties, the loads, the boundary conditions, etc. After the verifi-

cation of the above mentioned properties the operator can start the analysis.

The former Italian embassy in Tirana (Fig. 6a) was chosen to test this pro-

cedure herein described. It is a 3 storey masonry building of the XX. The

model (Fig. 6b) was completed in Autodesk Revit and then it was exported and

imported in SAP2000. After a general control of the model and the mesh gen-

eration, it was used to complete all the structural verifications. In Fig. 7 the

deformed shape of the building under the seism action in the transversal direc-

tion is shown (Angjeliu, Baballëku, 2013).

Crack pattern and structural analysis

An integral part of the geometrical model should be the crack pattern,

which is closely related to its structural behaviour as it is a direct result of dif-

ferent loading conditions. In Revit software there is not a dedicated feature for

drawing the crack pattern. This problem was overcome by drawing the cracks

by simple lines. The crack drawn simply in views and sections are transferred

directly in the 3D model. This adds another feature to the BIM model for the

documentation of the crack pattern. At this point the research was focused in a

way to model the crack so to be imported in the calculation model. In practise

not all the cracks are of the same importance. The user must choose the most

significant cracks to represent as discontinuities in the calculation model. An-

other procedure was developed by dividing the created wall entities through the

previously drawn cracks in order to make them exportable in the FEA software

(Fig. 8).

The model imported in SAP 2000 is represented by 2D shell elements

whereas the Abaqus model is represented by 3D solid elements. Though differ-

ent approaches must be followed in either software. In Sap2000 the crack will

be modelled by link elements assigned in the borders of the cracks (Fig. 9).

Differently in Abaqus this procedure can be run easily by using the avail-

able interface elements. The properties to be assigned can be derived by ex-

periments or chosen in the literature. The crack should divide an element in

two or more different parts resulting in separate entities. This could be a new

tool to be inserted in a BIM software. The introduction of this new possibility

in BIM environment is shown in the proposed algorithm by modifying the

processes named “1” and “2” (Fig. 10).

This modifications aim to improve the model calculation accuracy and as

consequence the analysis results itself. The procedure is still not robust enough

for an automatic export/import action but in perspective can be simplified by

using OAPI (Open Application Programming Interface). This procedure

could be run as a plug-in in Revit and include the automatic cracks import and

mesh of the panel creation and assigning the link or interface elements in the

crack borders.

Control system of NDT data

After a non-destructive testing and monitoring campaign (Cardani, Binda,

2013; Binda et al., 1998) there is a large quantity of results (graphs, images,

reports, etc.) saved usually according to their location in the assessed building.


140

At least that there is no personalized software for the data control, you have to

search the location in the plants and then open the file in the containing folder.

A new future possibility of BIM in the management and control of this

large amount of data is by creating a plug-in or by utilizing the current available

tools in BIM software to make easy to call the files where the information is

being stored. By clicking on the virtual sensors disposed on the BIM model the

user can visualise the required results.

On the other hand the results of sonic testing, radar, thermography or sin-

gle and double flat-jack can be applied as images directly on the BIM model

and so to be read directly by the user (the simplest version). The designer can

view at the same time the NDT or monitoring results next to the BIM 3D

model, making so the results easier to be analysed.

Going back to crack pattern analysis it could be of help, checking in BIM

the behaviour of some cracks over time during the cracks monitoring. In Fig.

11 is shown the BIM model and an example of the virtual sensor placed in the

cracked masonry wall and next to it are visualized the result of the crack

movements over the monitored time.

The use of BIM in the creation of a data control system as presented above

can be a new advantage of this technology, but still a lot of research needs to be

carried out in this field in order to adapt the BIM technology to historic archi-

tectural heritage.

Conclusions

CSI SAP2000 and Simulia ABAQUS, two wide-spread structural analysis

software and Autodesk REVIT were chosen for the research. Along the article

are discussed different aspects about the BIM, the interoperability with struc-

tural analysis software, the documentation of the crack pattern, the improve-

ment of the calculation model with the introduction of the crack pattern and

the creation of a control system of NDT data and monitoring tests results.

The results show that the IFC 2x3 format doesn’t offer good results so in

the moment it is not a recommended choice; the SAP2000/ETABS export

format .erx offers good results not only for the geometry but also for the mate-

rial and section properties, weather the ABAQUS ACIS .SAT format offers the

most complete features for import/export of 3D geometry.

The documentation of the crack pattern in the BIM model shows another

advantage of the technology. The cracks easily drawn in views and sections are

automatically placed in the 3D model. Then throughout techniques currently

available in BIM software the cracks can be exported in the calculations soft-

ware. The cracks then to be fully active can be completed in their boards with

link or interface elements.

Another future possibility of the BIM software is the creation of a data

control system of the NDT datas and monitoring test results that could be a

future development of the current technology.

As conclusion, the combination of the design, documentation and the data

control system in a unique model presents one of the main features of the BIM

technology, which is making the difference with the classic CAD.
