RISPlastic Hinge Model and Displacement-Based Seismic Design Parameter Quantifications for Reinforced Concrete Block Structural Walls
Publisher: American Society of Civil Engineers
Abstract: A practical alternative to the traditional rectangular cross sections of reinforced masonry structural wall systems is to alter the wall ends to allow for smaller compression zone depths, and thus higher curvatures to ...
Seismic Performance Parameters for Reinforced Concrete-Block Shear Wall Construction
Publisher: American Society of Civil Engineers
Abstract: The focus of the current study is to analyze previously reported test results to evaluate equivalent plastic hinge lengths for concrete-block shear walls and to extract related seismic performance parameters. Inelastic ...
Seismic Response Modification Factors for Reinforced Masonry Structural Walls
Publisher: American Society of Civil Engineers
Abstract: The current North American design standards provide seismic force modification factors for the rectangular masonry structural walls category only; no similar provisions for flanged and end-confined masonry structural walls ...
Behavior of Fully Grouted Reinforced Concrete Masonry Shear Walls Failing in Flexure: Experimental Results
Publisher: American Society of Civil Engineers
Abstract: In this paper, the possibility of achieving a high level of ductility by flexural yielding in fully grouted reinforced concrete masonry shear walls is evaluated. Six full-scale walls were tested to failure under reversed ...
Alternative Strategies to Enhance the Seismic Performance of Reinforced Concrete-Block Shear Wall Systems
Publisher: American Society of Civil Engineers
Abstract: In this paper, seven reinforced concrete-block shear walls with aspect ratios of 1.5 and 2.2 (two- and three-storey high) were tested under displacement-controlled cyclic loading. The response of rectangular, flanged, and ...
Characteristics of Rectangular, Flanged, and End-Confined Reinforced Concrete Masonry Shear Walls for Seismic Design
Publisher: American Society of Civil Engineers
Abstract: This paper contains detailed analyses of an experimental study conducted to evaluate the ductility, stiffness degradation and energy dissipation characteristics of rectangular, flanged, and end-confined reinforced masonry ...
Detection of Ungrouted Cells in Concrete Masonry Constructions Using a Dielectric Variation Approach
Publisher: American Society of Civil Engineers
Abstract: In this study, a new technique for detecting ungrouted cells in concrete block masonry constructions was developed. The concept, based on detecting the local dielectric permittivity variations, was employed to design ...
