预应力型钢混凝土梁刚度的计算方法研究

Research on the caculating methods of the rigidity of the PSRC beams

在对预应力型钢混凝土梁受力全过程分析的基础上,提出了利用三个不同的有效工作截面分析预应力型钢混凝土梁的不同受力阶段的方法,并给出了相应的刚度计算公式。

On the basis of analysis of the whole process of loaded PSRC, three different efficient working sections were brought forward to analyze the different phases of the PSRC bearing capacity, and the corresponding formulations were given, as well.
