填充墙对结构连续倒塌影响的研究进展

RESEARCH PROGRESS ON INFLUENCE OF INFILL WALL ON PROGRESSIVE COLLAPSE OF STRUCTURE

  • 摘要: 作为最常用的非结构构件之一,填充墙对结构抗震性能的影响已被普遍认知,并认为在分析和设计时忽视其存在不符合实际情况。对于结构的连续倒塌问题,目前仅获得了填充墙对结构抗连续倒塌性能影响的有限知识。填充墙的存在能够提高结构连续倒塌时的初始刚度和抵抗力,改变荷载的传递路径,最终导致结构的破坏模式和破坏位置改变。该文从试验研究、数值分析和设计方法三个方面系统综述了国内外关于填充墙对结构连续倒塌影响的研究现状。介绍了在现场和试验室两种不同场景下,基于拆除构件法的填充墙框架结构连续倒塌试验研究概况。总结了宏观模拟和精细化模拟两类填充墙框架结构连续倒塌的数值模拟方法。归纳了填充墙框架结构的抗连续倒塌设计方法。在此基础上,分析了该领域已有研究的不足并结合发展趋势对未来研究方向提出了建议。

     

    Abstract: As one of the most commonly used non-structural components, the influences of infill wall on the seismic performance of structures have been widely recognized, and it is considered that ignoring its existence in the analysis and design is not compatible with the actual condition. However, up to now, only limited knowledge about its influences on the progressive collapse resistance of a structure have been obtained. The existence of infill wall can improve the initial stiffness and resistance of the structure during progressive collapse, change the load transfer path, and eventually change the failure mode and failure location of the structure. This paper systematically reviews the research state-of-the-art of the influences of infill wall on progressive collapse of structures from three aspects: experimental research, numerical analysis and design method. The research status of progressive collapse test of an infill-wall frame structure based on the dismantling component method in two different scenarios of field and laboratory are introduced. The numerical simulation methods for progressive collapse of the infill-wall frame structure are summarized, including macro simulation and fine simulation. The progressive collapse resistance design methods of the infill-wall frame structure are summarized. On this basis, the shortcomings of existing research and the suggestions for future research in this field are analyzed.
