【 摘 要 】

The performance-based structural design requires that the structure has a clear structural performance target under the specified set-up criteria, and the performance target is specifically reflected in the structural damage degree. This paper analyzes in detail the strength criteria of structural failure. Combined with the actual bridge-building project, the dynamic elasto-plastic analysis of the fiber unit is used to obtain the transverse and longitudinal ductility of the structure. Being destroyed, the displacement of the structure and the study of energy dissipation failures have been carried out. It is known from the research that the ductility of the analyzed engineering structures is good and meets the requirements of the current specifications, and can be used as a useful reference for structural seismic design.
