Truck loading and truck path definition to simplify analysis of bridge systems.General purpose linear-elastic 3-D frame and finite element analysis program.WinSAC (Structural Analysis and Correlation The BDI Suite of analysis and modelling software (WinSac, WinGen and WinGRF) was designed to make the integrated approach a routine process. The BDI-STSII eliminates these hassles and allows the structural engineer to concentrate on evaluating the structure. Furthermore, other systems often require soldering and other tedious procedures in order to assemble them. The BDI-STSII was developed because most data acquisition systems are so application-general that they require an electrical engineer or computer specialist to configure them. The BDI-STSII allows a typical short- to medium-span bridge or similar structure to be instrumented and load tested with up to 64 sensors in less than a day by a two-person crew. Developed through the experience of field testing more than 200 structures, the BDI-STSII is very portable, lightweight, and efficient to implement. (BDI-STSII) has been designed expressly for performing live-load tests on highway and railroad bridges. The Structural Testing System II by Bridge Diagnostics, Inc.
