Superior ductility of moment‐resisting frames allows for high response modification factors, therefore design for smaller earthquake loads. In contrast, to limit the lateral drift, the cross‐sectional dimensions of the beams and columns are increased, which deactivates the benefits of the achieved high response modification factor. The linked beam frame system is proposed in this paper to decouple the strength and drift criteria. The link elements are added between the beams of two adjacent stories in spans where allowed architecturally to control the drift while they also increase the potential sources of energy dissipation. The design procedure is straightforward and prevents the trial and error analysis required for conventional moment‐resisting frames. The effect of the links on the lateral stiffness of the structure is estimated, and prototype buildings of five, 10, and 15 stories are investigated using linear and nonlinear analyses. A comparison of the results between the proposed system and the conventional method indicates that in addition to simplification of the design procedure, saving of about 10% to 15% in steel material of each lateral load resisting frame is achieved.

解耦钢制框架中的强度和漂移准则

抗矩框架的出色延展性可实现高响应修正系数，因此可设计用于较小的地震荷载。相反，为了限制横向漂移，增加了梁和柱的横截面尺寸，这取消了获得的高响应修正系数的好处。本文提出了一种连接梁框架系统，以消除强度和漂移准则。链接元素被添加到跨度中两个相邻楼层的梁之间，在结构上允许控制漂移，同时它们也增加了潜在的能量耗散来源。设计程序简单明了，可避免常规抗弯框架所需的反复试验分析。估算链节对结构的侧向刚度的影响，使用线性和非线性分析研究了五层，十层和十五层的原型建筑。所提出的系统与常规方法之间的结果比较表明，除了简化设计程序外，每个侧向承重框架的钢材还可节省约10％至15％。
