SUMMARY OF ULTIMATE LOAD CAPACITY ANALYSIS FOR LONG SPAN CONCRETE CABLE-STAYED BRIDGES

This paper introduces the present situation in research into utimate load capacity analysis of long span concrete cable-stayed bridges. The analysis methods and problems that need to be solved for geometric and material nonlinear behavior of concrete cable-stayed bridges are presented. Reference to the study of utimate load capacity of long span concrete cable-stayed bridges is also provided. It is pointed out that the method of inner force plastic fators is a good method for material non-linear analysis and T.L or U.L equations are satisfied for structural geometrical non-linear analysis of cable-stayed bridges.
