| In view of the fact that the research of the assembled shear wall structure system in our country tends to focus on the seismic performance and less on the energy-saving effect of the whole structure,this paper presents a new type of assembled shear wall board which considers both the force and the energy-saving.The main work of this paper is as follows:(1)Finite element analysis software is used to model the panel,and finite element analysis of a shear wall is carried out based on the modeling method in this paper.The analysis results are basically consistent with the experimental data.(2)Finite element analysis of three new assembling shear wall panels with different aspect ratios was carried out to study their failure modes and compare with the common solid shear wall panels with corresponding aspect ratios.The results show that the failure modes of new shear wall panels are worse than those of ordinary shear wall panels when the height-width ratio is low,and they are the same when the heightwidth ratio is high.(3)The parametric finite element analysis of the mechanical behavior of the new type of assembled shear wall panel is carried out,including the aspect ratio,axial compression ratio,concrete strength and the ratio of horizontal distribution of reinforcement.The results show that the larger the ratio of height to width,the smaller the maximum horizontal bearing capacity and the better the ductility of the shear wall;the larger the ratio of axial compression,the greater the maximum horizontal bearing capacity of the shear wall,and the worse the ductility of the shear wall;the ductility of the model is inversely proportional to the concrete strength;and the horizontal bearing capacity is proportional to the concrete strength With the increase of reinforcement ratio,the maximum horizontal bearing capacity and ductility of the model are improved.(4)The finite element analysis software is used to analyze the static and dynamic characteristics of a new type of assembling shear wall panel.The results show that the new shear wall residential model has smaller structural stiffness and larger natural vibration period than the ordinary shear wall residential model,and the maximum interstory displacement angle of the new shear wall residential model is less than the limit value of the code,indicating that the new shear wall residential model has good seismic performance. |
