Mesoscopic finite element analysis on seismic performance of ductile energy-dissipating wall of reinforced concrete
摘要
Abstract
Installing ductile energy-dissipating walls in base-level is an effective way to enhance their seismic performance.Using finite element analysis software,this study establishes a meso-scale finite element model of reinforced concrete ductile energy-dissipating walls and analyzes the variation in seismic performance under different loading strain rates.The results show that the meso finite element model can accurately simulate the mechanical performance indicators and failure modes of the structure well.When the wall is held constant,increasing the strain rate has a limited effect on the load-bearing capacity of the energy-dissipating wall specimens,with a maximum improvement of approximately 6.6%,but it significantly affects the deformation capacity,increasing the ductility coefficient by up to 26.9%.Under the same strain rate conditions,specimens with energy-dissipating walls arranged in parallel demonstrate better seismic performance than single-wall specimens,with the ductility coefficient increasing by up to about 17.8%.关键词
