摘要
本文旨在探究民用建筑新增墙体端柱-剪力墙结构的抗震性能,并确定影响其抗震性能的具体因素。以江苏省泰州市某民用建筑项目为例,针对该建筑中的新增墙体端柱-剪力墙结构,构建计算模型,并在确保其他条件不变的情况下,采用ABAQUS软件构建有限元模型,探究新增墙体端柱-剪力墙结构抗震性能的具体变化。即有限元模拟的滞回曲线比试验曲线更加饱满,捏缩效应不及试验明显,骨架曲线比试验曲线下降慢。最终得出民用建筑中,新增墙体端柱-剪力墙结构的抗震性能主要受到横截面尺寸的影响,而混凝土强度等级的改变对于该结构的安全系数及抗震性能的影响不明显,在实际应用中针对新增墙体端柱-剪力墙结构抗震性能没有达到预期目标的情况,可通过调整横截面尺寸和结构配筋率的方式改善。
This paper aims to explore the seismic performance of the new wall end column-shear wall structure in civil buildings,and determine the specific factors affecting its seismic performance.Taking a civil building project in Taizhou City,Jiangsu Province as an example,a calculation model was built for the new wall end column-shear wall structure in the building,and the finite element model was built using ABAQUS software to explore the specific changes in the seismic performance of the new wall end column-shear wall structure under the condition that other conditions remained unchanged.That is,the hysteretic curve simulated by finite element method is fuller than the test curve,the pinch effect is less obvious than the test curve,and the skeleton curve decreased slower than the test curve.Finally,it is concluded that in civil buildings,the seismic performance of the new wall end column-shear wall structure is mainly affected by the cross section size,while the change of concrete strength grade has no obvious impact on the safety factor and seismic performance of the structure,in practical applications,the seismic performance of the new wall end column-shear wall structure does not meet the expected goal,which can be improved by adjusting the cross section size and structural reinforcement ratio.
