摘要
概述了交错桁架的产生,介绍了交错桁架的结构组成,分析了交错桁架的结构特点。以某学生公寓为例,根据交错桁架的特点,提出了平面有限元计算模型,将其在荷载下的结构响应与空间模型计算结果进行比较。结果表明,二者计算结果相近,说明可以通过对平面模型的计算分析代替对三维模型的计算分析,从而为交错桁架提供了简化的设计方法,有助于其在工程中的推广应用。
The generation and constitution of staggered truss system is summarized. The characteristic is also analyzed. Taking a students apartment as a case study, considering the characteristic, 2-dimensional model of the staggered truss system is brought forward and comparison is done on the structural response of the 2-dimensional model and 3 - dimensional model. They accord with each other well. It is illustrated that the staggered truss system can be analyzed by 2-dimensional model instead of 2-dimensional model. Then a simplified design method is put forward for the staggered truss, which can improve the application of staggered truss system in practice project.
