文档介绍：论框架结构的发展趋势
摘要:框架结构由梁柱构成,构件截面较小,因此框架结构的承载力和刚度都较低,它的受力特点类似于竖向悬臂剪切梁,楼层越高,水平位移越慢,高层框架在纵横两个方向都承受很大的水平力,这时,现浇楼面也作为梁共同工作的,装配整体式楼面的作用则不考虑,框架结构的墙体是填充墙,起围护和分隔作用,框架结构的特点是能为建筑提供灵活的使用空间,但抗震性能差。

The development trend of the frame structure
Abstract: The frame construction are constructed by beam columns, the relatively small inter-part contact surfaces determined the low bearing capacity and stress feature is similar to the vertical cantilever shear beam, whose horizontal displacement decelerates with the increasing hight of floors. The frame structure at a high floor bears massive pressure both vertically and horizontally, and meanwhile , the locale poured floor collaborates as one of the beams . The effect of the integral floor construction should not be considered because the frame-constructed wall is infilled, thus having a guarding parting effect. The beauty of the frame construction is the possibility to provide more flexible choices of usage space for the building, however, the earthquake resistance is sacrificed for that purpose.

1 引言
目前,住宅承重结构的设计基准期一般为50年。人们用十几年以致终生的积蓄购买一套住房,在使用几十年后就要报废,这种现实真的有点残酷,所以人们很迫切的要求提高住宅的耐久性。现在,超耐久性混凝土的研究正在兴起,在不远的将来有望使混凝土的耐久性达到几百年以上。当住宅采用框架结构之后,我们就可以采用超耐久性混凝土,从而大大提高住宅的耐久性,实现我们拥有超耐久性住宅的梦想,有显著的经济效益和社会效益是不言而喻的。
