考虑薄膜效应的钢筋混凝土双向板承载力分析
Load-carrying capacity analysis of reinforced concrete two-way slabs considering membrane effect
摘要
Abstract
To easily determine the load-displacement curve of reinforced concrete two-way slabs ,the modified segment equilibrium method was established based on the yield-line theory ,and the three-stage mode was proposed ,in which the tensile membrane effect was taken into account in this meth-od .Additionally ,the nonlinear procedure for modeling the behavior of reinforced concrete two-way slab was developed according to the object-oriented method and the theory of shell finite element .The two methods were used to predict the load-displacement curves and ultimate loads of reinforced con-crete two-way slabs .The nonlinear program was also used to verify the rationality of modified seg-ment equilibrium method .The result shows that compared with the finite element model ,the modi-fied segment equilibrium method is simple and easy to calculate ,and it is capable of predicting the load-displacement curves and ultimate loads of reinforced concrete two-way slabs with reasonable accu-racy .关键词
