某斜拉桥索力设计要点分析

Key Points of Cable Tension Design of Cable-Stayed Bridge

斜拉桥属于高次超静定结构,其设计较一般梁式桥复杂得多。斜拉索的索力设计是斜拉桥设计中的关键部分。以印尼某斜拉桥的索力设计为例,介绍应用"桥梁博士"软件进行索力设计的要点,以供同行参考。

Cable-stayed bridge belongs to high-order hyperstatic structure, the design of which is much more complicated than common girder bridge. The design of cable tension is the critical part of the design of cable-stayed bridge. Taking the cable tension design of a cable-stayed bridge in Indonesia, the paper introduces the key points of cable tension design based on the software known as Doctor Bridge, which can be consulted by peers.
