【摘要】 当前对钢筋混凝土剪力墙的研究和现行规范,基本都集中在双排配筋剪力墙方面,这也是因为当前剪力墙主要应用的地方是高层建筑和超高层建筑。本文研究了一种应用在新型复合多层剪力墙住宅结构体系中的剪力墙,该种多层结构剪力墙采用双向单排配筋,外墙采用复合墙体以满足节能要求。这种新型结构主要适用在高烈度区的多层住宅建设,采用这样的结构形式能满足高烈度区的抗震要求。研究了L、T和Z三种截面形式剪力墙构件的承载力及其抗震耗能能力。通过以上研究工作得出以下结论:①建立了6个截面形式分别为:L型、T型和Z型,每种截面的剪力墙各2个,模拟轴压比为0.3的条件下,分别沿模型的工程轴向和非工程轴向做了低周反复荷载试验模拟,通过对试验模拟结果的对比,分析了实验的单排剪力墙的承载力、刚度退化、滞回曲线、耗能能力和破坏特征。②在模拟结果的基础上,修改了模型的配筋率、混凝土级别和轴压比等参数,进一步分析了单排配筋剪力墙构件承载力的规律。③双向单排配筋混凝土剪力墙经过合理设计和构造措施,能够满足多层住宅结构抗震要求。本文得出的结论和构造建议可供设计参考。更多还原

【Abstract】 Due to the wide application of the double row RC shear wall, the current research and specification of RC shear wall are mainly concentrated in double row RC shear wall. In this paper, a new building structure system of composite and energy-saving RC shear wall for multistory residence building which adopts bi-directional single row of steel bars and exterior composite wall to meet energy requirements was studied. This type of new structure is mainly used in the high intensity multilayer residence. In this way, multistory buildings can not only meet the earthquake requirements of high intensity, but also avoid too much increased cost. Based on the experiment and finite element analysis, this paper studied the bearing capacity and the seismic energy dissipation capacity on the residential structure of multi-story L、T and Z-shear wall structure with bi-directional single row of steel bars.Main contributions are listed as follows:①In order to study the capability of earthquake resistant and mechanical capability on the residential structure of multi-story L、T and Z -shear wall structure with bi-directional single row of steel bars, this paper uses two 1/2 reduced scale’s L、T and Z -shear wall with bi-directional single row of steel bars models with certain enforcements ratio of RC, separately along the web plate direction and the flange direction, to test the load-carrying capacity, stiffness, degenerated process and aseismatic behavior of the two models, then analyze and evaluate the horizontal load-carrying capacity. The test results show that RC shear wall node with bi-directional single row of steel bars meet the seismic requirements.②Based on the analyzed results, using the concrete structure design specification of concrete and reinforced of the constitutive curve,we had the giant general ABAQUS software did the simulation which leaded to a good result that simulation curves are consistent with the experiments results and the analyzed reinforcement in simulation ABAQUS which generate the applicable range and shear wall defects.③Based on the analyzed results, the mechanical model and formulas of bearing capacity of the RC shear wall with bi-directional single rows of steel bars was established and the results obtained from the formulas and those from analysis were in good agreement.With reasonable design and structural measures, RC shear wall with bi-directional single row of steel bars node can satisfy the seismic requirements for multilayer residence structure. The seismic design suggestions put forward in this paper and the related experimental results can be a reference for the seismic design.更多还原
