Abstract

Reinforced concrete shear wall system (RCSW) is one of the most prevalent lateral force-resisting systems in high-rise buildings worldwide. With increasing demands for superior seismic performance, constructability, and cost-effectiveness, various new technologies have been proposed in recent years. Among these, the controlled outriggered rocking wall (CORW) system is developed as a promising solution to improve the seismic performance of conventional RC shear wall systems. CORW system combines a damped outrigger (at roof level) and a controlled rocking (at the base) to a conventional RC shear wall system. In this study, the seismic performance of the conventional RC shear wall system is compared with the same system with a damped outrigger (at roof level), the same system with controlled rocking (at the base) and the CORW system. The results show that the seismic performance of conventional RC shear wall system can be significantly improved by introducing either, (a) damped outrigger at roof level, (b) controlled rocking at base level, or using the proposed CORW system.

期刊介绍： Engineering Structures provides a forum for a broad blend of scientific and technical papers to reflect the evolving needs of the structural engineering and structural mechanics communities. Particularly welcome are contributions dealing with applications of structural engineering and mechanics principles in all areas of technology. The journal aspires to a broad and integrated coverage of the effects of dynamic loadings and of the modelling techniques whereby the structural response to these loadings may be computed. The scope of Engineering Structures encompasses, but is not restricted to, the following areas: infrastructure engineering; earthquake engineering; structure-fluid-soil interaction; wind engineering; fire engineering; blast engineering; structural reliability/stability; life assessment/integrity; structural health monitoring; multi-hazard engineering; structural dynamics; optimization; expert systems; experimental modelling; performance-based design; multiscale analysis; value engineering. Topics of interest include: tall buildings; innovative structures; environmentally responsive structures; bridges; stadiums; commercial and public buildings; transmission towers; television and telecommunication masts; foldable structures; cooling towers; plates and shells; suspension structures; protective structures; smart structures; nuclear reactors; dams; pressure vessels; pipelines; tunnels. Engineering Structures also publishes review articles, short communications and discussions, book reviews, and a diary on international events related to any aspect of structural engineering.
