ABSTRACT

Limiting values of column-to-beam moment capacity ratio (MCR) that ensure a desirable collapse mechanism has been presented by many international standards as well as published literature. However, compliance of such requirements is reported to be computationally involved, which makes it unattractive to the design office. Also, the studies on the effectiveness of this requirement in terms of seismic performance of the building and associated cost-benefit are limited. The present study proposes an alternate scheme of MCR for the capacity design of RC framed building, which is easy to comply with and leads to an economical design without affecting its seismic safety.

摘要

许多国际标准和已发表的文献已经提出了确保理想倒塌机制的柱梁弯矩承载比 (MCR) 的极限值。然而，据报道，这些要求的合规性涉及计算，这使得它对设计办公室没有吸引力。此外，关于这一要求在建筑物抗震性能和相关成本效益方面的有效性的研究是有限的。本研究为 RC 框架建筑的容量设计提出了一种 MCR 替代方案，该方案易于遵守，并在不影响其抗震安全性的情况下实现经济设计。
