Seismic isolation design method for arranging seismic isolation supports across layers

Abstract

The invention provides a seismic isolation design method for arranging seismic isolation supports across layers. The method comprises the following steps that S1, a seismic isolation layer is composed of an upper seismic isolation structure and a lower seismic isolation structure, and the upper seismic isolation structure and the lower seismic isolation structure are arranged on upper and lower adjacent floors correspondingly; and S2, a plurality of shear walls are arranged on the lower seismic isolation structure, and the thickness or length of the shear walls is adjusted to improve the lateral stiffness so as to achieve the damping effect. The seismic isolation design method can solve relevant problems caused by arranging seismic isolation supports across layers in a large range, and expand the application range of seismic isolation design in engineering practice.

Description

technical field [0001] The invention relates to the field of seismic isolation design of industrial buildings, civil buildings, bridges and other buildings, and more particularly to a seismic isolation design method for setting seismic isolation bearings across floors. Background technique [0002] my country is a country with frequent earthquakes. In recent years, major earthquakes have occurred successively in Wenchuan and Ya'an. The earthquakes have caused a large number of casualties and huge property losses. The destruction of infill walls and decoration sub-structures caused casualties. Therefore, it has been repeatedly mentioned at the government level that it is recommended to promote seismic isolation technology to improve the seismic performance of structures to ensure the safety of human life. Some areas with high design intensity are forced to adopt seismic isolation technology for important buildings, which greatly promotes earthquake isolation in my country. dev...
