基于日本学者Hitaka提出的开竖缝钢板剪力墙的初始弹性刚度公式,采用两种支撑体系简化计算开缝墙体。通过有限元建模分析,研究开缝参数不同时,简化模型模拟开缝钢板墙性能的差异,主要分析了简化模型与开缝墙体之间的弹性刚度误差、弹性刚度误差与开缝设计参数之间的关系,并对简化模型的计算公式进行修正,得到性能更加接近于开缝墙体的修正简化模型。
Two types of conventional brace systems were employed in steel plate shear wall with slits (SPWS) in order to simplified calculation, based on the initial elastic stiffness formula of SPWS proposed by Hitaka. It was mainly studied the difference between simplified model and SPWS influenced by two parameters of slits, using FEM. The elastic stiffness error between simplified model and SPWS was studied in detail, which explored the relation of with this error the design slits parameters. By analysis of the error, the calculation formula of simplified model was modified aiming to acquire modified simplified model that could simulate SPWS approximately.
