Nonlinear Analysis of the Effect of Horizontal Construction Joint on the Flexural Behavior of Reinforced Concrete Slabs
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 6
Abstract
The Study of the behavior of slabs under the influence of horizontal construction joints has become necessity in the case of large thickness slabs such that raft and some special cases of flat slabs which were casted in two or more layers. The first layer is usually casted up to cover the reinforcement steel mesh and the other layers were casting to get the actual thickness of slabs. The purpose of this research is to examine the effect of horizontal construction joints on the behavior of simply supported slabs. A commercial non linear finite element program, such as "ANSYS version 12" [1] was used to study the previous slabs. The results which obtained from theortical analysis wre comared with that obtained from expermintal work [2]. The main parametric study used in this search was the case of interface layer between the two layers of the reinforced concrete slabs. A comparison was made between the slab which was casted as one layer and to that slabs which were casted in multy layers with different interface properties the results showed that the results from theortical modeling and expermintal work were nearly approximate as well as the studding of horizontal construction joints on the flexural behavior of slabs is very important.
