摘　　要：矩形构筑物各组成板块的计算模型有多种,目前主要是两种方式:一种是分离式,一种是整体式,但两种方法均有利弊。本文主要采用空间弯矩分配法的理论分析该类结构的受力特性,并考虑了该结构水平向弯矩的影响,该方法解答思路清晰,结果准确,可供设计人员参考。Disconnect-type model and unitary-type model are primary calculation models to analyze component plates of rectangular structures at present.They have advantages and disadvantages at the same time.Considering the influence of horizontal bending moment,the spatial bending moment distribution method was applied to analyze the mechanical characteristic of this kind of structure in this paper.The method is clear and the results are accurate,and it can be used for reference.
