Influence Of The Superstructure And Foundation Interaction On The Elastic Foundation Beam

This paper is based on the program PKPM-JCCAD which is developed by ChinaAcademy of Building Research, specialized in elastic foundation beam calculation. In-depthanalysed the influence factors of the upper structure and foundation soil on the elasticfoundation beam, and further verified the PKPM-JCCAD to winkle foundation beam of theaccuracy of the calculation.A whole structure is composed by the upper structure, the foundation and the soilfoundation. The three parts are connected with each other. Due to the complexity of theproblem itself and the objective conditions brought by computing technology development, ina long period of time, the civil engineers design the structure using a direct and simplemethod without considering the three individuals’ mutual influence and function, so will makethe calculated results very big. And will cause the design either with hidden unsafe problemsor will waste the material. This paper will not do the calculation separately, so the structurewill meet the static equilibrium of the total load and force condition.This article dicussed the interaction’s factors. Factors such as subsoil model (includinglinear and nonlinear), foundation types (this paper mainly studies the elastic foundation beam,and the stress process of the deep beams), the upper structure stiffness (various types of loadand the corresponding stiffness on then due to construction process, the stiffness of theforming process) and the overall analysis of the interaction Through this paper’s large amountof calculation and analysis, it can be seen that, in the structural design if the interactionprocess can be fully considered, it will maximize the balance of the structure’s safety andeconomic effect.
