【摘要】 随着近百年来随着商业化、工业化、城市化及社会生产的发展和人民生活的需要,高层建筑逐渐的发展起来,同时科学技术的进步、轻质高强材料的出现以及机械化、电气化、计算机在建筑中的应用等,又为高层建筑的发展提供了物质和技术条件。高层建筑的高度越来越高,结构构形式也不断发展,钢-混凝土混合结构在超高层建筑中得到了广泛的应用。 结构要同时承受垂直荷载和水平荷载,还要抵抗地震作用。在多层结构中,水平荷载的效应较小,对设计不起控制作用;而高层结构中,水平荷载和地震作用将成为控制因素。由于目前国内外对钢-混凝土混合结构的抗震研究的较少,且对混合结构在地震区的应用看法不一,而我国又是一个多地震国家,因此对混合结构抗震进行系统的研究是很有必要的。本文即利用时程分析程序CANNY99对典型的混合结构形式输入典型的地震波进行抗震计算,通过对钢框架和混凝土核心筒刚度比的变化对承载力的影响,得出钢框架与混凝土剪力墙的刚度合理匹配值在1:50左右的一般性结论,为今后混合结构的设计提供参考。更多还原

【Abstract】 With the development of commercialization, industrialization, city development and the productive forces and the increasement of the people’s standard of living in these years, the high-rise buildings develop quickly in these years.At the same time with the development of science and technology ,the appearance of the light material with high intensity and the application of mechanisam, electrization and the computer in the architecture, all these provide the substance and technology condition for the high-rise building’s development.The mixed steel-concrete structure has been widely used in the ultra -high buildings with the development of the height and structural alterations of the buildings.The structure not only bears the vertical forces and the horizontal forces, but also resists the seism action . In the lower structures, the action of horizontal forces on structures are very small and usually they are neglected;In the multistory building, the action of horizontal forces on structures become outstanding generally.Due to the fewer rtsearchs on the function of resisting earthquake of steel-concrete structure both inside and outside our country at present,and also due to the various viewpoints to the application of this kind of structure in the earthquake zone considering our country is a frequent earthquakes land,therefore,tiis quite necessary to carry on a systemtic study upon the function of resisting earthquake of the steel-concrete structure. This paper aims at calculating resisting earthquake by adopting analysis process CANNY99 and inputting the typical earthquake wave to the specific mixed structure,hence,the general conclusion will be drawn about the matching rationally value of rigidity is 1/50 of steel frame and concrete shear wall,it will offer reference for the design of the mixed structure in the future.更多还原
