網頁The results of several experimental studies indicate that steel shear walls show an acceptable seismic performance in terms of providing significant stiffness, strength, ductility, and energy dissipation to the buildings. They have small strength and stiffness degradation, and hence provide the building with a stable seismic response. 網頁2024年7月18日 · Despite the increase in the use of cold-formed steel (CFS) in mid-rise construction (up to 5 storeys), the North American cold-formed steel standards AISI S400 and S240 do not provide a standard design procedure for CFS sheathed and framed shear walls for use in such constructions.
網頁2014年12月11日 · When this technique is used to reinforce an existing RC building, the primary structure (RC frame) should bear the gravity loads, while shear walls should be designed to resist horizontal actions, thanks to the development of a tensile diagonal strips mechanism (tension field). 網頁1995年6月1日 · Steel shear walls for existing buildings Engng J.

網頁2015年12月3日 · This study investigates a seismic retrofit method for existing reinforced concrete (RC) frame by using steel plate shear wall (SPSW). The SPSW resists the lateral forces primarily through the tension field action of the slender infill panel. 網頁2024年6月9日 · Corrugated steel plate shear walls (CoSPSWs) consist of corrugated steel wall plates and a steel boundary frame, which could be adopted as seismic-resistant systems for high-rise buildings. In this study, a performance-based seismic design (PBSD) method was proposed for CoSPSWs, in which an ideal yield mechanism and target drifts …
網頁2016年11月3日 · The most efficient means of accomplishing this is usually to provide vertical bracing or shear walls oriented in each principle direction, which must be coordinated with functional and aesthetic requirements for partitions, doors, and windows.
