摘要
本文提出了考虑内部刚度分布层单元构造方法。该法将楼板视为剪切弯曲深梁,并用单元平均刚度、刚度偏心距和弹力半径来构造侧移刚度分布。以U型和L型结构为算例,用反应谱方法和时程分析方法计算分析了隔震体系性能参数对非规则结构的局部变形的影响。
A story element structure method considering interior stiffness distribution is suggested in this paper.In the method,floors are considered as bending-shear beams and floor stiffness,elasticity radius and eccentricity of stiffness are used to form element horizontal stiffness distribution.The U and L shaped structures are taken as examples.The influence of performance parameters on the local deformation of the isolated irregular buildings are calculated and analysed by spectral response method and time-history method.
