摘要: 細腰型樓蓋常見于高層及超高層住宅建筑.結構設計應通過計算分析得到地震作用下細腰型樓蓋內(nèi)力,并使其具有足夠的承載能力,保證整體結構可靠工作.現(xiàn)行規(guī)范對細腰型樓蓋給出了概念設計及對應的構造措施,但并未給出明確的計算分析方法.反應譜及時程分析方法尚不能得到細腰型樓蓋相連結構相互錯動產(chǎn)生的細腰型樓蓋面內(nèi)剪力和彎矩,存在安全隱患.在美國建筑規(guī)范 IBC 2003 基礎上,提出了一種更合理的細腰型樓蓋地震作用效應分析新方法,該方法已推廣應用于國內(nèi)一批住宅項目,有利于保證含細腰型樓蓋高層超高層建筑結構抗震安全性.
關鍵詞: 細腰型樓蓋;平面不規(guī)則;地震作用效應;地震剪力系數(shù)

Abstract: Narrow connected floor is used in high-rise and super high-rise residential building. The structure design shouldobtain the internal force of the narrow connected floor under earthquake action through calculation and analysis,and makethe floor have sufficient bearing capacity to ensure the safety of the overall structure. The current code provides theconceptual design and corresponding construction measures for narrow connected floor,but does not provide a calculationand analysis method. The shear force and bending moment in the narrow connected floor caused by the mutual dislocation ofthe narrow connected floor connected structures cannot be obtained by the response spectrum and time-history analysismethod,and there is a potential safety problem. Based on America building code IBC 2003,a new method of earthquakeaction effect analysis of the narrow connected floor was proposed,and the method has been widely applied in a number ofresidence projects in China,which is beneficial to ensure the seismic safety of high-rise and super high-rise buildings withnarrow connected floor.
