QConBridge™ Overview
QConBridge™ is a live load analysis program for continuous bridge frames.   This software has been developed for the Alternate Route Project. QConBridge™ performs live load analysis for the AASHTO LRFD Bridge Design Specification HL93 live load model. The software accommodates standard and user defined DC and DW dead loads, and performs Strength I, Service I, Service II, Service III, and Fatigue Limit State combinations.

QConBridge™ is licensed with the Alternate Route Open Source License.
