Abstract


The development of the building structure system becomes one of the pre-task in engineering at present, with the alteration and innovation of traditional building technique and implementation of the policy on walling material and energy saving. Be directed against the shortcoming of traditional shear wall, such as the large self-weight, stiffness and seismic action, an new type of slitted shear wall combined with keep-warming layers and dissipating energy forms,is represented in this paper. This new type shear wall not only has the advantages of traditional shear wall, such as the good bearing capacity of horizontal loading, but also overcome the shortcoming of traditional shear wall, such as the large self-weight, stiffness and large earthquake action. Appling the new type of shear wall to multi-story and sub-high rise structures, these can be come into being that include reducing self-weight, stiffness, earthquake action, and improving ductile, saving material,and the need of heat proof and saving energy can be satisfied too.Based on the advantages of the shear wall, six model specimens were designed and fabricated. By cyclic reversed loading test, the structural dynamic performances such as internal force, deformation behavior and failure proceeding of the specimens, under the different ratio of axial compressive force and connecter forms have been investigated. The simulative models of nonlinear FEM were planed basing on the results of the experiment. The calculative outcomes agree with the experimental results, which prove the accuracy of the calculating model. By utilizing ANSYS program, the factors which impact the seismic behavior regularity of reinforced concrete shear wall such as strength of concrete, ratio of axial compressive force and the form of energy-dissipating install were analyzed.It is shown that the new type of shear wall can greatly improve the seismic and energy-dissipating behavior of reinforced concrete hollow shear wall from the results of investigation. The results of research showed that the new type of the multi functional shear wall has multi seismic resistant system. To set the vertical slit and connects on the wall can effectively affect the seismic behavior of shear wall structure. If setting the vertical slit and connects reasonably, the seismic and deformation behavior of shear wall can be improved greatly, with the bearing capacity is reduced a little degree. The energy-dissipating mechanism of multi functional shear wall was studied, and the hysteretic model of energy-dissipating shear wall was represented in this paper. The results provide the reference for its design and application in engineering.
