后张法预应力混凝土超静定结构计算次弯矩心得

Research on Calculation of Secondary Moment of Statically Indeterminate Structure for Post-tension Prestressed Concrete

通过对后张法预应力混凝土超静定结构计算次弯矩等效荷载的学习,直接从结构力学力矩分配法出发,求次弯矩影响产生的综合弯矩,力学概念明确,易为学习者领会.

This paper is to calculate secondary moment equivalent load of statically indeterminate structure for post-tension presstressed concrete. Based on moment distribution of structural mechanics, comprehensive moment caused by secondary moment is calculated. The mechanics concepts are clear, which is easy for learners to understand.
