Pseudo-Plate method for the design of high-strength concrete prestressed waffle slab containing steel fiber
In this paper,basing on the disadvantages on waffle slab in practice and comparing the high-strength steel fiber concrete with prestressed technology,a new prestressed high-strength concrete composite waffle slab structure containing steel fiber is introduced,which includes material composite and structure type composite.Because adding steel fibers can improve the capacity of the concrete,so it also can make some influence on the mechanic performance of prestressed high-strength steel fiber concrete composite waffle slab,such as elastic module,shear module,flexural rigidity,and torsion rigidity and so on.So by the analysis of the material and mechanic capacity and considering the influence of prestressed and steel fiber,the formulas to calculate flexural rigidity,torsion rigidity,deflection and internal force of the new composite slab are given,in which the waffle slab is equivalent to orthotropic slab by the principle of stiffness coincidence.The study in this paper can provide some valuable theory references for further study and application of wall-slab structure.
