摘要：错层是楼板标高大于600mm以上,且超过梁高，错层的面积必须大于等于整个楼层面积的30%。这种结构,属于建筑方案不规则的结构形式。首先是平面,每层的楼板由于标高不同,相当于楼板开大洞,所以平面不规则; 其次是竖向,由于梁板错层,竖向构件的刚度会相差很大,所以竖向也不规则。在试验和研究中均表明,错层结构的抗震性能较差,应尽量避免,但是又有市场需求,为解决好这个矛盾,在实际的设计过程中,就要注意采取加强措施。本文探讨了高层建筑错层结构抗震设计。

Abstract: The split-level floor elevation is greater than 600mm or more, and more than high beam, split-level area must be greater than or equal to 30% of the entire floor area. This structure belongs to the irregular structure of the building program. The first is flat on each floor a different elevation, which is equivalent to the floor to open a big hole, so the plane is irregular; followed by vertical slab split-level, the stiffness of the vertical elements will vary greatly, so the vertical nor the rules . Trials and studies show that poor seismic performance of the split-level structure should be avoided, but there are market demand, to resolve this contradiction in the actual design process, it is necessary to pay attention to be taken to strengthen measures. This paper discusses the seismic design of high-rise building split-level structure.Key words: high-rise buildings; split-level; structure; seismic design

引言

随着楼市的发展，人们传统的居住习俗正逐渐受到新潮理念的挑战，旧式的居住观念已被迅速发展的现代都市生活理念所替代，在住宅的品位和生活质量上人们已提出了一个相当高的要求，这种要求的提高也势必引起房型的变化，人们要求现在的房型功能更完善、分割更合理、私密性更强。也就是人们对住宅的要求已从以前传统的实惠型向舒适性、小康性、超前性、休闲性、温馨型发展。为此错层式住宅作为一种新概念房型在各地层出不穷，甚至有愈演愈烈的趋势，已经从独立式、联立式的低层住宅发展到多层，又由多层蔓延到高层。

所谓错层, 就是楼板标高大于600mm以上,且超过梁高。光有了这样的元素还不能构成错层结构,错层的面积必须大于等于整个楼层面积的30%。……
