摘要

引入钢筋和混凝土的应变率效应

利用有限元分析软件ABAQUS中的显示动力分析模块ABAQUA/Explicit

对钢筋混凝土梁在不同单调加载速率下的受力性能进行了数值模拟。通过比较不同加载速率下的分析结果

探讨了地震作用下的动态荷载对钢筋混凝土粱受力性能的影响。分析结果表明

在动态荷载作用下

钢筋混凝土梁的受力性能有显著变化

其承栽力随加载速率的提高而提高

且极限强度的提高要较屈服强度明显。

Abstract

By introducing the strain rate effect into this paper

the dynamic analysis module ABAQUA/Explicit is used to simulate and analyze the fracture behavior of reinforced concrete beams under different monotonic loading rates.By comparing the results of the analysis under different loading rates

the performance of reinforced concrete beams is discussed.The results show that the fracture behavior of reinforced concrete beam under dynamic loading force significantly change

the bearing capacity of reinforced concrete beam increases with the increase of the loading rate

and the ultimate strength improves more obviously than the yield strength.
