DYNA Force® Sensors for Load Monitoring

Introduction

On many occasions during the construction and service life of a structure, it is beneficial to know the force in the tension element of the post-tensioning system� Although there are many methods to measure the tendon force, most of them are cumbersome, expensive, and the accuracy differs

depending on the method used� DYWIDAG has been involved in the development, testing and execution of DYNA Force® to measure the force in the tendon� DYNA Force® is utilized for ground anchors, soil nails, in cable stay bridges and structures to measure the forces during construction and to

monitor forces during the service life of the structure� Valuable information about load distribution can be obtained if sensors are placed along the bond length of ground anchors or soil nails� DYNA Force® can be used for bare, epoxy-coated and greased-sheathed steel�

Advantages and Characteristics

DYNA Force® is manufactured based on the theory that the permeability of steel to a magnetic field changes with the stress level in the steel� By measuring the change in a magnetic field, the magnitude of the stress in the steel element can be obtained� The DYNA Force® system does not alter the characteristics of the tendon other than its magnetization� The permeability is a function of temperature and magnetization� A calibration process eliminates the impact of these variables� The system considers the effect of the temperature change automatically�

A portable Power Stress unit is attached to wire leads from the DYNA Force® sensor� This unit will create the magnetic field, measure the residual value and then convert it to a direct force reading�

The DYNA Force® system is robust, requires no maintenance and has no moving parts� It is composed of cylindrical, non-contact sensors and a Power Stress unit (read-out box)� DYNA Force® sensors are installed over the strand or bar during construction and a zero reading is taken before applying any post-tensioning force�

It is expected to have a similar service life as structure� This will allow the owner to regularly monitor the forces in the post-tensioning system in minutes as a part of their inspection procedures without the need for lift-off equipment or other special expensive techniques� Monitoring with DYNA Force® also avoids the inaccuracies and risks often associated with lift-off readings� Performing the monitoring requires only one person�

Remote Load Monitoring of Ground Anchors at Willow Island Hydroelectric Project, West Virginia, USA

DSI supplied twenty-eight 59-0�6" strand anchors for the stability and safety of the dam at the Willow Island Hydroelectric project in West Virginia, USA� Rock mass was excavated to allow for the installation of a power generator�

In order to monitor the forces in the anchors during rock excavation, three sensors were installed in each anchor� A total of 84 DYNA Force® Sensors were installed in these permanent rock anchors� All sensors were connected to a multiplexer using extension cables, and all multiplexers were connected to the readout unit via main cable� Modem, controller and Cell SIM card were installed so the data could be accessed from a remote location� Battery and solar panels were used to power the readout unit� The data from all of the sensors are being taken remotely every three hours, analyzed and reported to the owner�

Continuous Monitoring of Ground Anchors at Sellwood Bridge, Oregon, USA

DSI supplied 56 DYNA Force® Sensors for both permanent and test ground anchors for Sellwood Bridge in Oregon, USA� The main purpose was to monitor the slope stability in front of the bridge abutment� Six sensors were installed in the bond length and one in the free length of each of the test anchors� Two sensors were installed in each of the permanent anchors, with the number of strands varying from 8 to 24� Fifteen automated readout units were installed to record the force readings of the sensors every four hours� Software was provided so that the engineer could transfer the recorded data to a laptop� DYNA Force® Sensors provided valuable information for both test and permanent anchors�

DYWIDAG Micropiles – GEWI® Pile

A GEWI® Pile is a drilled and grouted micropile, with a diameter of less than 12 inches� It is centrally reinforced with either one or a group of DYWIDAG THREADBARS� The deformations on the bar transfer the load into the surrounding grout body and friction transfers the load from the grout into the ground�

Drilling: ■ Compact lightweight drilling equipment allows for pile installation even in areas with low headroom

■ Small economic drill hole diameters ■ Drill holes can be placed closely to existing walls or structures

■ Vibration free drilling prevents damage to adjacent structures

Continuous coarse thread on bars: ■ Provides excellent load transfer into grout

■ Remains threadable even when dirty or damaged

■ Allows for splicing and extending the bar at any point

Double Corrosion Protected (DCP) bars may be utilized for piles in aggressive ground�

Multiple bars can be installed into a single borehole�

Short bar sections with couplers can be utilized in low headroom locations�

DYWIDAG Tie Rods


Tie Rods produced from DYWIDAG THREADBAR® are used for a variety of applications� Constructions of marine bulkheads for various docking facilities have, for many years, benefited from the use of DYWIDAG Tie Rods� Facilities such as barge and ship docks as well as offshore platforms have found the system to be a cost effective alternative to large diameter A36 Tie Rods with upset threads�

Additional applications for DYWIDAG Tie Rods are: ■ Stabilization of slopes ■ Horizontal load resistance for foundations and roof structures

■ Bracing for grade separations

Tie Rods produced from DYWIDAG THREADBAR® offer various economical and technical advantages: ■ Coarse thread allows for rough site handling as dirty or damaged threads will remain threadable

■ Continuous thread allows for easy on-site length adjustments since cutting or coupling of the rod is possible along its entire length

■ Stock length up to 60ft ■ Bars conform to ASTM A615 or ASTM A722

■ ASTM A615 bars are about 50% less weight than A36 bars

■ ASTM A722 bars are about 70% less weight than A36 bars

■ Available with many options for corrosion protection

■ DYWIDAG Tie Rods can be tensioned for sheet pile alignment

■ The DYWIDAG Tie Rod system is approved by many construction authorities worldwide

Waler Connection

Short bolts are needed to connect a standard sheet pile wall or a modular sheet pile wall to a load distributing double channel beam� This can be done with Grade 75 or Grade 80 DYWIDAG THREADBAR®�

The required length of the bar depends on the depth of the sheet pile profile, the width of the beam, the plate thickness and the nut length�

DYWIDAG Permanent Strand Anchors with DCP (Double Corrosion Protection)


� Strand anchors allow for a large range of anchor capacities, as there is no theoretical limit on how many strands can be used in an anchor

� Long anchor lengths are possible without the requirement of a splice

� Most strand anchors are coiled for transport and require little storage space on site

� Utilization of high strength 270KSI strand results in low anchor weight

� The hot melt extrusion process provides a high quality, uninterrupted plastic bond breaker and additional corrosion protection

� Specialized installation and stressing equipment is available from DSI
