Abstract: Based on the concrete damage plastic model and direct integral algorithm, the refined dynamic elastic-plastic analysis was carried out for the main plant structure of a large heat engine plant. The deformation performance, the stiffness degradation regularity and the weak position distributions of the main plant structure were studied, and the quantitative indicators for integral elastic-plastic performance of the main plant structure were given. The failure patterns of typical members as staggered members and the shear wall with big restrained beams were studied. The dynamic elastic-plastic analysis results were compared with the results of the 1∶7 scaled pseudo-dynamic test. The dynamic elastic-plastic analysis results agree well with the test results, which verifies the accuracy and feasibility of the dynamic elastic-plastic analysis.
Keywords: dynamic elastic-plastic analysis; refined finite element analysis; heat-engine plant; main plant
