Seismic reinforcement analysis and measurement research of reinforced concrete frame structure

Abstract

In China, there are many reinforced concrete frame buildings that have reached the end of their design life, or have not been designed with seismic requirements in mind and need to be reinforced. In this paper, a reinforced concrete frame structure which needs to be reinforced is taken as an example. Two common reinforcement methods are used to reinforce the reinforced concrete frame structure by adding shear wall and increasing column section. BIM-GSSAP software is used to analyze maximum inter-storey drift angle and the member response under frequent earthquakes, and the whole structure of the weak layer under rare earthquakes is checked. The results show that both methods can significantly improve the seismic performance of buildings. At the same time, combined with the project example, the advantages and disadvantages of the construction process are analyzed, which can provide a useful case reference for this kind of reinforced concrete frame structure projects.
