【摘要】：随着我国经济高速发展,大量不规则的高层及超高层建筑出现。为了符合使用功能,建筑内部设立通高大堂,结构平面大开洞,将造成空间布置上形成穿层柱、大开洞等复杂的结构形式,这些复杂结构的出现要求在结构设计中特别注意。另外近几年地震频发,对于复杂建筑抗震性能的研究越来越深入,以确保其达到“大震不倒”的抗震设防目标。本文以某带穿层柱Z字平面框一剪结构作为实例,结合基于结构性能抗震设计方法,展开以下几方面内容的计算分析工作：1、本文采用SATWE和midas Building两款软件,在多遇地震作用下依照振型分解反应谱法对结构进行弹性对比分析,确保了结构符合规范“小震不坏”的抗震设防目标。2、在罕遇地震作用下结构进入塑性破坏,本文采用PKPM中的PUSHEPDA和midas Building两种弹塑性分析软件,对结构进行静力弹塑性对比分析。分析结果表明结构符合规范“大震不倒”的抗震设防目标,构件损伤机制符合“强柱弱梁”的规范要求。3、为了反映结构在地震动下的真实响应,采用PUSHEPDA程序对结构进行动力时程分析。分析结果表明三条地震波选取合理,结构能符合规范“大震不倒”的抗震设防目标。4、在罕遇地震作用下分析了穿层柱的受力性能,分析结果表明穿层柱拥有较好的抗震能力,塑性铰滞后出现。
[Abstract]:With the rapid economic development of our country, a large number of irregular tall and super-high-rise buildings appear. In order to meet the use function, the high hall is set up inside the building, and the structure plane has a large opening, which will result in the formation of complex structural forms such as perforated columns and large openings in the space arrangement. The appearance of these complex structures requires special attention in the structural design. In addition, in recent years, the seismic performance of complex buildings has been studied more and more deeply in order to ensure that the seismic fortification target of "strong earthquake will not collapse" is achieved. In this paper, with the example of a plane frame shear structure with a cross layer column Z character, combined with seismic design method based on structural performance, the following calculation and analysis work: 1 is carried out. In this paper, two kinds of software, SATWE and midas Building, are used in this paper. Under the action of frequent earthquakes, the elastic analysis of the structure is carried out according to the mode decomposition response spectrum method, which ensures that the structure conforms to the seismic fortification target of "small earthquake is not bad", and under rare earthquake, the structure enters into plastic failure. In this paper, the static elastoplastic analysis of the structure is carried out by using two kinds of elastoplastic analysis softwares, such as PUSHEPDA and midas Building in PKPM. The analysis results show that the structure conforms to the seismic fortification target of the code "strong earthquake does not collapse", and the damage mechanism of the member conforms to the requirement of "strong column and weak beam", in order to reflect the real response of the structure under ground motion, the structural damage mechanism meets the requirement of "strong column and weak beam". The dynamic time history analysis of the structure is carried out by using the PUSHEPDA program. The analysis results show that the selection of three seismic waves is reasonable, and the structure can meet the seismic fortification target of "strong earthquake does not collapse". Under the action of rare earthquake, the stress behavior of the perforated column is analyzed. The analysis results show that the perforated column has good seismic capacity. Plastic hinge lags appear.
