含三角形加劲阻尼装置框架之设计方法与应用
|
摘要
为使结构耐震设计更趋经济,建筑结构必须有效地吸收并消释大震输入能,采用三角形钢板之加劲阻尼装置可增加结构劲度和迟滞阻尼。本文按参数研究的结果提出适当之耐震参数与含三角形加劲阻尼装置框架的设计程序,并以六层楼结构作为新建结构的设计实例,分析结果显示即使在强震下,加劲阻尼装置可适度降低框架位移且使梁、柱构件保持在弹性范围。
In order to construct cost-effective building structures in regions of high seismic risk, building structures must be able to absorb and dissipate large amount of energy during a severe earthquake. Proper incorporating the steel triangular plate added damping and stiffness (TADAS) devices into a structure can increase the system stiffness and the hysteretic damping of the building. This paper presents the key design parameters and the seismic resistant design procedures for building structures incorporating the TADAS devices. The design procedures are illustrated using an example 6-story steel building structure. Analytical results show that the TADAS devices can effectively reduce the nonlinear demands imposed on the beams, columns and their connections.
