Experimental Study Of The Joint And Connection In A Two-way Prestressed Laminated Concrete Slab

This paper presents a detailed experimental study and ANSYS nonlinear finite element analysis of the edge joint in two- way prestressed laminated concrete slab. Firstly, based on the static load destructive experiment of the 15 different objects which are in different contact length, different bend angle, the laws of load-slip and the laws of bond-slip of them are researched. The experimental results show that the some of them performs excellent in strength and it meets the regular service conditions of bearing capacity and deformation. In the meanwhile, the experiment appearance and law about some of these objects are in according with the results and conclusion of the experiments which are practiced. Therefore, it can be conclude that the rational of the design of and the correctness of the research method on the experiment , also it can be demonstrated the truth and believable of the result.Furthermore, according to the relative bond-slip theory of the pioneer and experienced analytical method, the experiment appearance has been collected, and we can observed that ultimate bearing capacity and cracking load can be analyzed and calculated. And the edge joint method of reinforcing bars considering security is concluded.Lastly, nonlinear finite element analysis of these objects is proceeded adopting ANSYS program. Contrasting the curves of load-slip, bearing capacity, the deformation of the objects and the steel bar the divergence graph of crack, the finite element analysis is proved feasible and appropriate.Above-mentioned research findings can provide references for engineering application and further study of the two-way prestressed laminated concrete slab.
