Method for improving seismic performance of building structures based on cultural relics safety

Abstract

The invention provides a museum structure anti-seismic performance improving method based on cultural relic safety in order to avoid losses and damage of museum collections under the seismic action, and relates to the technical field of structural engineering and the field of museum relic protection. The museum structure anti-seismic performance improving method mainly comprises the steps of determining seismic oscillation input parameters, establishing a main structure finite element model, conducting conventional design and dynamic and time-historical analysis on the finite element model, and conducting adjustment according to the relation between the magnitude of anti-seismic performance-based indexes and an anti-seismic performance-based index limiting value so as to meet requirements and the relevant anti-seismic construction procedures such as anti-seismic construction of structural components and non-structural components, anti-seismic arrangement of exhibition halls and museum collection storage microenvironment construction. According to the museum structure anti-seismic performance improving method based on the cultural relic safety, effective control over the seismic action of the museum collections is conducted in the whole seismic spread process, the risk that large-scale damage is caused to the museum collections by seism is greatly lowered, and the full-life cost of museum buildings is effectively reduced.

Description

technical field [0001] The invention relates to the technical fields of structural engineering and cultural relics protection, in particular to a method for improving the seismic performance of building structures based on the safety of cultural relics. Background technique [0002] Museums, memorial halls, cultural relics protection and cultural relics management units serve as windows to show the whole process of urban civilization and historical development, and collect representative objects, artworks, documents, manuscripts, books and other cultural relics in various historical eras. This type of building structure undertakes Responsible for the restoration, storage and daily protection and management of cultural relics in the collection, it is of great significance to the inheritance of civilization and cultural transmission, and is an indispensable part of urban cultural construction. The centralized storage and management of historical relics and important exhibits a...

Problems solved by technology

[0004] The purpose of the present invention is to propose a method for improving the anti-seismic performance of building structures based on the safety of cultural relics, so as to solve the problem that the seismic design of existing structures does not fully consider the main structure of the building, floors, display cabinets and their dynamic coupling with the structure of cultural relics in the whole process of earthquake propagation. The impact of factors such as cultural relics on the safety of cultural relics, it is difficult to meet the needs of the anti-seismic safety of cultural relics; at the same time, it solves the problem that the existing technology does not give quantitative indicators for the anti-seismic safety control of cultural relics in the collection, and cannot guarantee the safety of cultural relics in the collection under the action of earthquakes, resulting in The collection of cultural relics has a great potential safety hazard
