现浇混凝土空心板两个方向的刚度存在差异,只有确定这种差异的大小,才能明确其正交异性或各向同性的归属。通过分析,给出现浇空心板两向刚度表达式,并通过对算例的分析,给出影响现浇混凝土空心板两向刚度的因素。
The stiffness of cast-in-place concrete hollow slab differs in both directions. Only by determining the size of this difference can the orthogonality or isotropy be identified. Through the analysis, the two-way stiffness expression of the poured hollow slab is given, and the factors affecting the two-way stiffness of the cast-in-situ concrete hollow slab are given through the analysis of the examples.
