Study On Seismic Behavior Of Longitudinal R.C Shear Wall With Frame Column In Main Factory Building Of The Large Capacity Power Plant

The seismic behavior of longitudinal middling-high R.C shear wall with frame column is discussed through model experimentations and finite element methods in this paper, after taking frame-shear wall structure of a main factory building of the large capacity power plant as experimentative prototype. The major work as follow:In order to appliance pseudo static test, the longitudinal middling-high R.C shear wall with frame column in the large capacity power plant's main factory building has been simulated to a model structure with 1/15 reduced-scale. The contents of study are process of cracking, course of damage, skeleton curve, rigidity degradation, ductility characteristic etc. That the seismic behavior of this kind of middling-high R.C shear wall is excellent has been proved by chubby hysteretic curve and fine capacity of energy dissipation. The experimentative load-carrying capacity attest that safety store is small, so it should strengthen structure capacity. Finally, the simple and applicable formula is presented in order to calculate the shear wall's displacement indifference phases.Firstly, the shear wall's load-carrying capacity, displacement, properties of ductility, shape of damage, distribution of plastic hinge are analyzed through delaminating combination finite element method with numerical value method. The result is accord with the experimentative result. Secondly, model structure's load-carrying capacity, deformation, crack's generation and development, structural strain and shape of damage are analyzed with SOLID65 element in software's structural calculation module. Finally it discussed the model structure's load-carrying capacity, deformation, shape of damage etc. through macro finite element analysis method. The three finite element analysis methods can precisively analyze middling-high R.C shear wall structure and apply in this kind of structural analysis.The study result indicate that the seismic behavior longitudinal middling-high R.C shear wall with frame column is good, so it can be apply in main factory building of the large capacity power plant. Moreover some advices for this kind middling-high shear wall's design and constitution are presented.
