大跨度次梁预应力次扭矩分析

The Inferior Torque Analysis of the Long Span Pre-stressed Secondary Girder

预应力次扭矩对结构受力的影响,存在于整个受力阶段,其对结构受力的反对称效应是比较明确的,尤其对边主梁的受扭影响。通过理论分析及工程模拟,指出预应力次扭矩是一个典型的协调扭矩。

The pre- stressed inferior torque to the structure stress influence, exists to the entire stress stage, it to the structurestress antisyrnmetry effect is quite explicit, especially the opposite side king post is turned the influence. This article through the theoretical analysis and the project simulation, pointed out the pre-stressed inferior torque is a typical coordinated torque.
