斜支撑桁架在大跨度结构中的应用

The practice of the truss which has raking shore in the long span structure

本文对斜支撑桁架结构在福建会堂大跨度建筑中的应用进行探讨 ,对其受力特点进行分析 ,确定各构件的刚度关系对杆件内力的影响、斜支撑对构件产生的轴力如何解决及其斜支撑产生的水平力对周围竖向结构的影响进行系统的研究 ,了解斜支撑桁架结构力学性能 ,应用后张有粘结预应力改善混凝土的力学性能 ,提高整个结构的承载力 ,对设计斜支撑桁架结构具有重要意义。

In the paper,we discussed the practice of the truss which has raking shore in the Fujian-Hall.We analyzed the distribution of stress in the truss and the influence of the rigidity of members.At the same time,we research the influence of the press which transfers by the truss to the main structure.In the end,we summarized the experience in this kind of structure.
