1. Improved Slab Design Feature using Basic and Additional Rebar

Design > Meshed Slab/Wall Design >Design Criteria for Rebars

• Improved slab design process provides additionally required rebars based on the basic rebars

defined by user in order to reflect engineering practice.

• Slab design results can be exported into DShop in which slab rebar drawings are generated.

• Basic rebars and additional rebars are

separately displayed in the legend.

• Basic rebars can be defined separately

for the X and Y direction of top & bottom

layers.

• Different basic rebars can be defined

for each sub-domains.

2. Inclined Slab and Wall Design Feature

• In previous version, slab and wall member could not be designed even with a slight slope.

In Gen 2012, the inclined slab and wall with various angle as shown below can be designed as

per Eurocode.

• Inclined slab members are designed based on out-of-plane forces. And inclined wall

members are designed based on in-plane forces.

When modeling a masonry structure in the previous version, the vertical direction of a

structure must be set to the global-Y axis or local-y axis of elements, which caused

inconvenience in some cases such as rotation of models, auto-generation of story data and

lateral loads. Now, the vertical axis can be set to the global-Z axis regardless of the direction of

local axes of elements. Also, the masonry wall is not necessarily located on the global X-Z

plane. It can be rotated about the global-Z axis with any angle from the global-X axis, which

enables us to model 3-dimensional masonry structures.

separately. In the previous version, the results for beam and truss elements were

merged into “Frame” type.

• It is useful when designing a building with dual frame system.
