Abstract

The invention discloses a high-rise building structure anti-seismic property optimization method based on a sensitivity coefficient method. The optimization method includes (1), creating a high-rise building structure model; (2), selecting one anti-seismic property index in a displacement angle or displacement ratio as an optimization target, and grouping structural members; (3), setting constraint conditions and a target function for structural member optimization; (4), making optimization variables into a variable combination matrix; (5), modifying values of the variables in the combination, and performing structural anti-seismic calculation analysis to acquire a design experiment data result; (6), subjecting the acquired design experiment data result to response surface fitting to acquire a sensitivity coefficient; (7), calculating the target function on the basis of the sensitivity coefficient. The high-rise building structure anti-seismic property optimization method has the advantages that the contribution degrees of the structural members in a high-rise building structure to the displacement angle or displacement ratio under the earthquake action can be analyzed quantitatively, and accordingly, the anti-seismic property optimization direction of the high-rise building structure is determined.

Description

technical field [0001] The invention relates to an optimization method for a novel structure anti-seismic design, in particular to an optimization method for the anti-seismic performance of a high-rise building structure based on a sensitivity coefficient method. Background technique [0002] China is an earthquake-prone country. From the analysis of the results of earthquake disasters, the seismic design of building structures plays a particularly important role in reducing earthquake disasters. In order to improve the anti-seismic performance of the structure and reduce the construction cost, it is necessary to conduct an in-depth analysis of the structure, adopt the method of fine design to optimize the design of the structure, ensure the quality of the anti-seismic design of the building structure, use materials in the parts most needed for anti-seismic structure, and reduce the waste of building materials . [0003] Optimal design is the comparison and selection of mul...
