Earthquake Collapsed Damage Simulation Analysis Of Reinforced Concrete Frame Structure Affected By SSI Effect

Frame structure is one of the most widely structure form in the practical application. Itassumes that rigid foundation to study its structure collapsed damage Generally, Rarelyconsidering soil-structure interaction effects. Because of the complexity of the problems, thecurrent engineering and academia in the research of this aspect is still very deficient. So, in thepaper, it does collapsed damage analysis and research of reinforced concrete frame structure byoil-structure interaction. It has certain theoretical value and engineering significance.This article briefly summarizes power constitutive relation of the soil and the upperstructure, theoretical basis of soil-structure interaction and the simulation analysis method. Itanalyses the superiority of structural failure which is based on display algorithm of central finitedifference and time integration. The algorithm is applied to the software. By using the softwareof LS-DYNA, soil model, rigid surface model and the reinforced concrete model is applied tothree-dimensional solid modeling of frame structure of considering oil-structure interaction tosimulate the analysis of collapse. According to specifications，it selects rare earthquake in eightdegrees zones. By delimiting no reflection boundary to deal with the boundary problem of soiland for rationally studying to consider soil-structure interaction on the frame structure collapsedfailure affected. The appropriate surface-face contacts method and parameters are defined tosimulate the movement of structure members. In this paper, six conditions is described theinfluence of the collapsed of considering soil-structure interaction to the frame structure.Post-processing technique is used reasonably. Then simulation results are outputted with avariety of ways such as graphics and animation. The results show that. It is high precision foranalysis of the destruction and collapse of frame structure of considering soil-structureinteraction and without regard to soil-structure interaction by using the article of this article. Byselecting the model of five layers and ten layer frame structure of different site conditionsrationally, inputting seismic wave and the defining the failure criterion. It can simulate famestructure of different site conditions from linear to the non-linear until the final the whole processof collapse of structure. By contrast analysis of collapsed failure process of frame structure ofdifferent site conditions, it can get influence factors of collapsed damage of consideringsoil-structure interaction to frame structure, especially in the higher layers. In this paper, the simulation results which are obtained by used ANSYS/LS-DYNAsoftware can reflect the actual status of earthquake collapsed damage of reinforced concreteframe structure. It can be used to reveal frame structure collapsed and damage mechanism,improve the structure seismic performance and it is base of actual structure design. Then guidethe structural Seismic fortification.
