Experimental study and design method of shear-dominated composite plate shear walls
Engineering Structures, 2020Abstract Many skyscrapers have used the Reinforced Concrete (RC) filled Composite Plate Shear Walls (CPSW). Based on in-plane shear tests on six shear-critical CPSW specimens and a RC shear wall specimen, the behavior of CPSW systems with stud or tie bar connectors, various connector spacings, and various axial compression ratios were reported.

Shear coefficients for thin-walled composite beams
Composite Structures, 1987Abstract The shear coefficient in Timoshenko beam theory is obtained for thin-walled beams constructed of laminated panels of composite material using a variation of the method due to Cowper. Formulae are presented for a class of such composite beams. Comparisons are made with Cowper's original formulae for the case of an isotropic beam.

Shear Strength of Concrete and Gypsum Composite Walls
Applied Mechanics and Materials, 2013Gypsum walls are a green product that helps to save energy and protect the environment. This paper investigates the shear strength of glass fiber reinforced gypsum (GFRG) walls fully or partially filled with concrete in the hollow cores. Eight full scale GFRG walls were tested. The shear performance of the tested walls, including the shear failure mode,

Modeling of RC shear walls strengthened by FRP composites
Structural Engineering and Mechanics, 2017RC shear walls are considered one of the main lateral resisting members in buildings. In recent years, FRP has been widely utilized in order to strengthen and retrofit concrete structures. A number of experimental studies used CFRP sheets as an external bracing system for retrofitting of RC shear walls. It has been found that the common mode of failure

Macro modeling of steel-concrete composite shear walls
Structures, 2020Abstract To date, many researchers have developed various types of macro models to simulate the general response of conventional steel plate and reinforced concrete shear walls. Although extensive numerical and experimental studies have been conducted to assess the seismic response of steel-plate concrete composite shear walls, a robust macro-model ...

Experimental seismic behavior of innovative composite shear walls
Journal of Constructional Steel Research, 2016Abstract In this paper, an innovative structural wall, named bundled lipped channel–concrete (BLC–C) composite wall, is proposed. The proposed wall consists of bundled lipped channels seam-welded together and in-filled concrete. Seven full-scaled specimens were tested under axial load subjected to cyclic lateral load.

Shear Strength of Composite Masonry Walls
1995A composite masonry wall consists of a wythe of brick and another wythe of concrete block. The cavity between the two wythes is grouted and the wall acts as a single unit. In such construction, the floor slab usually rests on the interior (block) wythe, and directly transmits vertical and horizontal in-plane loads.

Shear Coefficient in Orthotropic Thin-Walled Composite Beams
Journal of Composites for Construction, 1998The shear coefficient in Timoshenko beam theory is derived for thin-walled beams constructed of orthotropic laminated composite panels and new formulas for the common forms of thin-walled section are presented. The results are identical to Cowper's for the case of isotropic beams.
