Experimental Research On The Seismic Behaviors And Finite Element Analysis Of Frame-supported Short-leg Shear Wall Structure

Now, in the actual project, the short-leg shear wall structure system has been widely used, but the thory is not mature.Because the number of short-leg shear wall and architectural requirements, inevitably short-leg shear wall will be borne entirely by the case of transfer beam. Based on the two specimens of short-leg shear walls in the transfer beam and oblique central column increases conversion fu-style structure of pseudo static test, observed and recorded under a different form of transfer structure component cracking, yielding, determination of components of displacement and steel strain at the weak transfer beam, so that we can obtain the force components of the basic laws of. On this basis, comparative analysis of the structural transformation of two different forms of P-Δhysteretic, carrying capacity of the deterioration of the structure, deterioration of structural stiffness, plastic deformation and ductility of the structure, and structural damage characteristics and failure mechanism. Analysis shows that the different forms of structural transformation has great influence on seismic performance. Undre the load of haunched transfer structure,site of the energy dissipation is located in the bottom of the hole transfer beam, while the enertg dissipation of the column transfer structure is in the middle part of the bottom wall of limb.In this paper, based on experiments, structure by ANSYS software, finite element nonlinear analysis.Comparison with the analysis of results and the experimental structure, and the results showed that the analysis results is agree will with the the experimental in the load rang. Analysis model and the calculate parameters such as the base,can be used for further analysis.Analyzed the shear bear of the haunchd transfer and the inclined column transfer structure with the short-leg shear wall in the middle of the transfer beam.And also analyzed the different transformation with the shera walls attached to the pillars.Finally, analyzed the principal stress transfer in the different forms of structural transformation with the vertical load and the horizontal load by the principal stress vectors which come from the finite element analysis and the failure mode in the actual experiment.And also analyzed the damage characteristics in the different forms of structural transformation.
