| Abstract: | Due to the complexity of constitute materials,multi ribbed wall slabs′elastic constants are difficult to define.To solve this problem,the paper equals prototype slab to orthotropically fiber reinforced slab,according to the rule that the equivalent concrete section area of the latter remains the same as that of the former through fiber strengthening in horizontal and vertical direcions.The paper also establishes a mechanical model of equivalent slab.Meanwhile,the theoretical calculating formulas of elastic consants are derived.By simplifying the multi ribbed wall slab to equivalent slab made of isotropic material,practical formulas of elastic constants are given,which provide theoretical basis for engineering designing. |
