摘要:
基于西安地区近二十年来多数地裂缝已趋于低速率的稳定活动状态和最近几年我国地震发生较为频繁的现象,以西安地区某跨越活动性较弱的地裂缝的框架-剪力墙结构为研究对象,从地裂缝的三维位移活动特征出发,采用SAP2000 有限元软件, 将地裂缝的垂直沉降量和水平张拉量以初始位移的形式施加到不同工况的结构有限元模型支座上,对未采取防治措施和设置沉降缝的结构有限元模型分别进行高烈度多维多点地震作用和高烈度多维一致激励地震作用的非线性时程分析,得到不同工况下的框架梁塑性铰发展趋势、剪力墙的混凝土和钢筋应力云图、结构弹塑性层间位移角包络曲线等一系列研究结果,并对以上结果进行对比分析,从而较为清晰地揭示出该类跨越地裂缝建筑物在多维多点地震作用和多维一致激励地震作用下的工作特性和性能,为今后深入研究地裂缝作用对建筑物上部结构的损伤破坏机理和跨越地裂缝建筑物的防治措施提供重要参考.
Abstract:
Based on the phenomenon that most ground fissures have tended to be in the stability of the low rate state in the past two decades in Xi’an and the earthquakes occurred more frequently in our country in recent years, the thesis is aimed at using to use the finite element software SAP2000 to make a nonlinear time-history analysis with the three-dimensional displacement activity characteristic of ground fissures as a foundation. The research object is building of frame-shear wall striding ground fissure in Xi’an. In this thesis, the vertical settlement and horizontal tension of the ground fissure are applied to the bearing of the different SAP2000 finite element models in the form of initial displacement. By nonlinear time-history analysis of the finite element models without prevention measures under high-intensity multidimensional and multi-point seismic and high-intensity multidimensional and consistent excitation seismic as well as the nonlinear time-history analysis of the finite element models after setting settlement joint under high-intensity multidimensional and multi-point seismic and high-intensity multidimensional and consistent excitation seismic, it reveals a series of research results, such as the development trend of plastic-hinge, the stress nephogram of shear wall’s concrete and rebar, the elastoplastic interlayer displacement angle curve. With contrastive analysis, it clearly shows the characteristic and performance of these buildings on the crossing ground fissure under multidimensional and multi-point seismic action and multidimensional and consistent excitation seismic action, which provide an important reference for the further study of the function of ground fissure on the building structure’s damage mechanism and the prevention measures about the buildings on the crossing ground fissure.
