Determination of Limit Bearing Capacity of Statically Indeterminate Truss Girders
Determination of Limit Bearing Capacity of Statically Indeterminate Truss Girders

Summary/Abstract: After the theoretical base of the structurelimit analysis being presented, this paper presents thealgorithm for calculation of limit load in staticallyindeterminate truss girders. The algorithm is based onthe application of matrix structure analysis and is usedfor determining static and deformation values within thestructural limit analysis step by step method, which givesa detailed view into the behavior of a girder in a gradualload increasing, until the formation of failuremechanism. This algorithm has been the base for makinga computer program for determining the load limit intruss girders and this has been presented in this paper innumerical example and also presented in this example isthe application of linear programming in determinationof the limit load.
