FEM Analysis of Cooperative Effects of Formwork Supporting System and Concrete Floor
Abstract:
This Currently, researches on formwork supporting system are mostly based on integrated stability, while the contribution of the cooperative bearing effects of the formwork supporting system and the concrete floor to the reliability of a structure is ignored. In this paper, the necessity of the existence of the formwork supporting system in the construction process of a structure’s roof boards is established by analyzing the cooperative effects of the formwork supporting system and the concrete floor of a subway transfer station under construction through double nonlinear numerical method.It is also concluded that flat paraboloid is the shape of the trend of the horizontal displacement of supporting formwork system under two-way load by using finite element analysis, and the open side of the paraboloid is opposite to the direction of the force, which is completely different to the decreasing trend from the top to the bottom of the horizontal displacement of the formwork supporting system under one-way load.
