seismic design of reinforced concrete shear walls

An analytical approach to determine the need to provide transverse reinforcement at boundaries of reinforced concrete structural walls with rectangular, T‐shaped, or barbell‐shaped cross sections is presented. By relating the expected displacement demands on the building system to the local ...


A displacement based method for the seismic design of reinforced concrete shear wall buildings of regular shape is presented. For preliminary design, approximate estimates of the yield and ultimate displacements are obtained, the former from simple empirical relations, and the latter to keep the ductility ...


coupled shear walls in reinforced concrete constitute an efficient^gtructural system for seismic resistance . However, to satisfy the high ductility demand generated in the spandrel beams diagonal reinforcement is generally required. Such a system is unsuitable for structural masonry and rapid strength and stiffness.

The correction in this version says: “For diagonally reinforced coupling beams, ϕ = 0.85 for shear.


Seismic design of Reinforced Concrete (RC) dual systems is performed as an optimization problem for which the charged system search algorithm is utilized as an optimizer. An efficient structural modeling is also presented for this purpose. Here, first databases are created based on ACI seismic criteria for beams, columns ...


The Indian seismic design code, like most of the other national codes worldwide, is based on a prescriptive-force-based design methodology. In the present study, seismic performance and fragility of reinforced-concrete frame shear-wall buildings designed for Indian codes are investigated using the ...


The purpose of this project was to evaluate critical issues in the performance of reinforced concrete wall structures in the 2010 Maule earthquake, and to develop recommendations for improved shear wall design requirements for incorporation into U.S. practice. Work on this project involved: (1) the ...

systems, such as special reinforced concrete shear walls,. ASCE 7 §12.2.1 limits the building height. These height limits do not apply to special moment frames used alone or used in combination with shear walls to create a dual system. When concrete moment frames are selected for buildings assigned to Seismic Design ...


Yet these larger design forces usually do not pose a design limitation since the lateral strength of these systems is larger than that of ductile shear wall systems. The lessons learned from the seismic behavior of Chilean buildings show that de- tailing of reinforced concrete elements to absorb and dissipate energy through ...


This web seminar illustrates the design of cast-in-place reinforced concrete shear (structural) walls in low (B) to moderate (C) as well as high (D, E, F) seismic design categories (SDCs). Design is for shear as well as for combined flexure and axial loads. Ordinary shear walls are designed when the SDC is B or C, while ...
