通过对六层大开间组合结构的实验分析,得出了此种结构的受力特性、变形特征和抗震性能。并在此基础上,重点研究了结构刚度和侧移规律、结构抗震强度的计算,以及弯曲作用对结构刚度、侧移以及抗震能力的影响。研究指出,对于六层大开间组合结构,应取层间剪切模型作为计算刚度、侧移以及强度计算的依据。用该模型对结构进行计算,可知此种钢筋混凝土——砌体组合结构具有较好的抗震能力。
Through the experimental analysis of the six-story open structure, the force characteristics, deformation characteristics and seismic performance of this structure are obtained. On this basis, the structural stiffness and lateral displacement laws, the calculation of the seismic strength of the structure, and the effects of the bending action on the stiffness, lateral movement and seismic resistance of the structure are mainly studied. The study pointed out that for the six-story large-bay composite structure, the interlayer shear model should be used as the basis for calculating the stiffness, lateral displacement, and strength calculation. Using this model to calculate the structure, it can be seen that this reinforced concrete-masonry composite structure has better seismic resistance.
