摘要：After the theoretical base of the structure limit analysis being presented,this paper presents the algorithm for calculation of limit load in statically indeterminate truss girders. The algorithm is based on the application of matrix structure analysis and is used for determining static and deformation values within the structural limit analysis step by step method,which gives a detailed view into the behavior of a girder in a gradual load increasing,until the formation of failure mechanism. This algorithm has been the base for making a computer program for determining the load limit in truss girders and this has been presented in this paper in numerical example and also presented in this example is the application of linear programming in determination of the limit load.
