MULTIPLE-OBJECTIVE AND PERFORMANCE-BASED EARTHQUAKE PROOF METHOD OF ENGINEERING STRUCTURES
A multiple-objective and performance-based earthquake proof method of engineering structures comprises following steps: (1) Setting a performance target of the engineering structure; (2) Inputting different performance targets into a single degree of freedom elasto-plastic structural system to conduct a simulation test; (3) Continually adjusting a magnitude of an earthquake wave, confirming a functional relationship between a seismic influence factor and a structure cycle under achieving the different performance targets, and obtaining earthquake demand spectrum curve; (4) Utilizing an analytical method to obtain a relationship between a shearing force and a displacement in the engineering structure; (5) Transforming the relationship between the shearing force and the displacement in the engineering structure into the functional relationship between the performance and the displacement under the single degree of freedom system, and obtaining a structure performance spectrum curve; (6) Comparing a relationship between the earthquake demand spectrum curve and the structure performance spectrum curve according to the structure cycle, and evaluating anti-seismic performance of the structure under the different performance targets.
