摘要:
为研究竖向压应力和高宽比对砖墙体抗震性能的影响,以砖墙体抗震承载力典型试验试件为基础,利用有限元分析软件ANSYS建立适当的空间模型。根据砖墙体的破坏模式和材料性能把墙体划分成块体单元、灰缝单元以及接触单元,为各部分材料选用不同的本构关系模型与破坏准则。并将计算结果与试验结果进行对比,验证文中模型的可适用性。选用经验证后的模型,变换竖向压应力和高宽比,得出相应的结论:墙体的开裂荷载和抗侧承载力随着高宽比的增大明显呈降低的趋势;不同高宽比的墙体,竖向压应力的影响规律不尽相同。
Abstract:
Based on the test results of typical brick wall’s seismic capacity,a suitable space model is established by utilizing ANSYS to study the behavior of brick walls influenced by the vertical compressive stress and the height-to-width-ratio. Considering the failure mode and material properties, we divided the brick wall into block element,mortar joint element and contact element and adopted different constitutive models and damage criteria for each part material. The results of finite element analysis agree well with experiments, which suggest the applicability of ANSYS for brick wall’s analysis.If we adopt the proved models to establish the finite element model of the brick wall for different height-to-width ratios and different vertical compressive stresses,we may prove that the cracking-load and resisting lateral force capacity of wall reduce obviously.When the height-wide-ratio increases,the influence of vertical compressive stress is not the same for the walls with different height-to-width ratios.
