The Limit Analysis of Spatial Frames
In present paper we propose applying a successively approximative method to solve nonlinear programming problems of limit analysis of spatial frames by using a penalty linear programming. Such a success makes it possible to deal with such large type of nonlinear programming problems. The computational examples showed that the method has the advantages of higher speed, lower computing cost,simpler data preparation and etc.. The computing theory and the program will become an effective tool to seek the limit loading of spatial frames in the area of the offshore engineering and the civil engineering.
