摘要
针对历次地震中框架结构广泛出现的底部薄弱的破坏模式,提出了增设阶梯墙的损伤控制措施,即在框架结构中增加若干片等厚度,变截面高度的落地钢筋混凝土墙体。通过IDA分析和一个振动台对比试验论证了阶梯墙体系的优越性,结果表明阶梯墙体系能够有效控制结构的变形和损伤模式,实现结构各层变形的平均化,抑制薄弱层的出现,并且经济实用,构造简单,适合大规模推广应用。最后提出了基于静力弹塑性分析的阶梯墙设计方法。
As previous earthquakes have highlighted that the bottom story in RC frames is always damaged more seriously than the upper stories, an innovative seismic passive control system of stepped walls was introduced. Stepped wall systems add reinforced concrete walls of the same thickness but different widths into the frames. The advantage of stepped wall-frame structure was demonstrated by IDA analysis and a shake table comparison test. Results showed that the stepped wall system can effectively control the structural deformation and damage distribution, suppress emergence of the bottom yielding mechanism, and is simple, economical, and practical for large scale application. Finally, a design procedure based on the nonlinear static analysis was proposed.
