Design Theory Research To Reinforced Concrete Medium Thickness Plate

As to the attention of the engineering safety problems and some special requirements for the structure such as light hollow plate, heating plate, basement roof universal application, medium thickness plate in engineering application is used more and more widely. However, in consideration of thick plate of self-respect, plane inside and outside factors such as stiffness and transverse shear,the traditional sheet theory isn’t a good choice to medium thickness plate on research and application. Therefore, putting forward more simple and reasonable design method in engineering field for the reinforced concrete plate is a problem to be solved.Firstly, based on two pieces of different thickness of bidirectional board test studies, get the change rule of medium thickness plate under vertical load deformation and internal force, and then get the result that the test results and the theory of classical sheet elastic algorithm conclusion are not consistent, and then we know that plate thickness on the internal force and deformation will produce certain effect for medium thickness plate design; Secondly through comparing and analyzing the test results and the theory of sheet calculation results, it can be seen that the traditional sheet theory used for medium thickness plate is partial safety; Then through the two pieces of test board of ANSYS numerical simulation and comparing the experimental results, it can be seen that by selecting the appropriate parameter ANSYS analysis simulation can be used on the plate; Finally, through the quantitative analysis of the numerical simulation of the reinforced concrete plate on elastic stage plate thickness of the displacement components deflection and internal force influence,based on the traditional sheet theory basis, puts forward the corresponding correction coefficient, and then compared with the test results, we know that the correction coefficient method can be used as reference in medium thickness plate design.
