摘　　要：针对预制带肋底板混凝土双向叠合板按单向板设计时传力模式不合理,以及采用正交构造异性板方法求解时计算量大、不便于工程设计采用的问题,通过引入等效跨度比,提出了一种实用弹性计算方法:将双向叠合板的形状按等效跨度比修正后视作各向同性板计算。采用该实用弹性计算方法,仅需知道等效跨度比便可查用各向同性板的弹性计算系数进行双向叠合板的设计。Through introducing the equivalent span ratio,practical elastic calculation methods for concrete two-way composite slab with precast ribbed panels were presented,which resolve the problems of unreasonable load-transferring mechanism when using one-way slab design approaches,and huge calculations adopting structurally orthotropic slab design procedures and inconvenience to use in projects.Practical elastic calculation methods were conducted by isotropic slab according to two-way composite slab revised with equivalent span ratio.And only equivalent span ratio was required to construct the design of two-way composite slab by adopting the table lookup method of isotropic slab.
