摘要:
以框架结构和砌体结构为主要结构体系的多层建筑数量多，分布区域广。然而，在历次地震中，多层建筑破坏最严重，倒塌数量最多。震害调查发现，框架结构梁端塑性铰基本无法形成，强柱弱梁难以实现。其中部分底层空旷的结构形成了层屈服破坏机制，大多数结构则因填充墙的组合效应出现了竖向构件的脆性破坏。通过对典型多层建筑震害现象的剖析，发现各轴构件刚度和承载力不均匀是结构破坏的主要原因，分配内力大的构件因变形能力小，超过极限承载力时率先破坏，成为结构破坏和倒塌的触发点。由此提出了结构破坏和倒塌的“变形饱和”假说。选取典型的特征构件，设计了无填充墙的框架、带后砌填充墙的框架和带先砌填充墙的框架3种实验模型，通过对极限承载力和极限位移的分析，验证了多层建筑结构“变形饱和”破坏倒塌机理。
Abstract:
Multi-storey building with frame structure and masonry structure are numerous and widely distributed. In previous earthquakes, multi-storey buildings were damaged and collapsed most seriously. It is found that the plastic hinge is difficult to form at beam end of the frame structures so that the concept of strong column and weak beam can hardly be realized. The storey yield mechanism is formed in a few empty bottom structures, while the brittle failure of vertical members occurs in most structures due to the combined effect of infilled walls. In this paper, the seismic damage phenomenon of typical multi-storey buildings is analyzed. It is found that the uneven stiffness and capacity of each axis is the main factor of the failure. Due to the small deformation capacity, the members with large internal forces will be the first to fail when exceeding the bearing capacity limit, becoming the trigger point of structural failure and collapse. Therefore, the ‘deformation saturation’hypothesis of structural failure and collapse is proposed. Three kinds of experimental models are designed by selecting typical characteristic components, namely, the frame without infilled wall, the post-wall frame and the pre-wall frame. Through the comparative analysis of ultimate capacity and ultimate displacement, the failure and collapse mechanism of ‘deformation saturation’of multi-storey building structure is verified.
