Problems solved by technology

First of all, the vibration characteristics of anti-seismic supports and hangers corresponding to different design parameters (mainly the distance between supports and hangers and the cross-sectional area of ​​diagonal braces) are different. If the overall dynamic analysis of anti-seismic supports and hangers and building structures is established for each design parameter If the model is used to calculate the floor response spectrum, the amount of calculation is huge and the engineering practicability is poor

Abstract

The invention discloses an anti-seismic optimization design method of a building anti-seismic support-hanger. The method includes the steps: building a three-dimensional space analysis model of the building structure-anti-seismic support-hanger; selecting maximal space of the anti-seismic support-hanger and a minimum cross-sectional area of an inclined strut, and calculating maximum acceleration reaction of the anti-seismic support-hanger; calculating a floor response spectrum of a building structure, and correcting the floor response spectrum according to the maximum acceleration reaction toobtain a corrected floor response spectrum; building quadratic polynomial regression models among the maximum acceleration reaction of the anti-seismic support-hanger, the space of the support-hangerand the cross-sectional area of the inclined strut according to the corrected floor response spectrum; determining optimized design values of the space of the support-hanger and the cross-sectional area of the inclined strut. According to the method, polynomial regression models among earthquake actions of the anti-seismic support-hanger, the space of the support-hanger and the cross-sectional area and the support-hanger can be rapidly and accurately built, design parameters of the anti-seismic support-hanger are optimized, calculation result accuracy is ensured, and optimization design efficiency is greatly improved.

Description

technical field [0001] The invention relates to an anti-seismic optimization design method for an anti-seismic support and hanger of a building, belonging to the field of anti-seismic design of buildings. Background technique [0002] my country is a country severely affected by earthquakes. The number of strong earthquakes accounts for 33% of the global continental strong earthquakes, and it is the country with the most continental strong earthquakes in the world. In many earthquake disasters, in addition to the devastating damage caused by the collapse of building structures, the damage of non-structural components, especially the damage of electromechanical equipment, affects the normal operation of the entire building function. Relatively speaking, the destruction of building auxiliary mechanical and electrical equipment will not only cause huge property losses, but also bring life danger, and the secondary disasters and tertiary disasters caused by this are potential th...
