摘要
为使建筑结构层间的弹塑性位移角满足《建筑抗震设计规范》要求,确保酒店建筑结构的稳定性,提出在双向地震作用下酒店建筑结构层间弹塑性位移计算方法.根据酒店建筑结构层间的弹塑性弯曲变形和剪切变形,分析酒店建筑结构层间梁截面的受力情况;基于酒店建筑结构层间钢筋和混凝土架构关系,计算酒店建筑结构层间弹塑性变形;在双向地震作用下,根据结构层间能耗构建酒店建筑结构层间弹塑性位移关系,获得酒店建筑结构层间弹塑性位移.试验结果表明,采用本文方法计算的双向地震作用下的酒店建筑结构层间弹塑性位移结果均符合规范1/100限值要求,能够有效确保酒店建筑结构的稳定性.
To ensure that elastic-plastic displacement angle between the floors of the building structure meet the requirement code“Anti-seismic Design Standard of Buildings”,a calculation method of the elastic-plastic displacement of such buildings in bidirectional earthquake is proposed.According to the elastic-plastic bending deformation and shear deformation between the layers of the hotel building structure,the stress of the beam section between the layers is analyzed.Based on the relationship between the reinforcement and concrete structure,the elastic-plastic deformation between the layers of the hotel building structure is calculated.In the case of two-way earthquakes,through the energy consumption between the layers of the structure,the elastic-plastic displacement relationship between the layers of the hotel building structure is constructed,and the elastoplastic displacement is thus obtained.The experimental results show that the calculation results of the interlayer elastic-plastic displacement of the hotel building structure in bidirectional earthquakes by the proposed method meet the requirements of the 1/100 limit value of the code,and can effectively ensure the stability of the hotel building structure.
