Load Deflection Characteristics of Sustainable Infilled Concrete Wall Panels

Abstract

Development of sustainable concrete has now become a mandatory requirement today due to environmental problems posed by the production of conventional concrete. Many researchers focused their research toward finding alternate materials for cement, sand, steel, etc., and came out with good results. This paper focuses on feasibility of developing sustainable concrete using bamboo as infill, stiffener, and combination of infill and reinforcement in the wall panels. In addition, low-density polyethylene waste also tried as infill material with bamboo as diagonal member. The structural property of bamboo was studied for replacing the conventional steel by designing the wall panels with lower stiffness and weight to avoid the catastrophic effect. The strength and behavior of infill wall panels for different infill cases were studied under uniaxial in-plane loading. Parameters such as maximum load carrying capacity, load-deflection characteristics, and cost effectiveness of bamboo-based wall panel system were considered in the present study. From the experimental results, it was understood that bamboo-based wall panel behaved as a ductile member and failed after due to the formation of micro-cracks. Wall panel specimens were failed B G. Dhinakaran with an out-plan buckling and resisted the force such that the sudden collapse was avoided. It was concluded that an infill wall reduced lateral and vertical deflection, thereby decreasing the probability of collapse. Hence, an infill wall panel could be used as a substitute for conventional wall panel.

Study on Seismic Behavior of Steel Frame-Steel Shear Wall with Assembled Two-Side Connections

“…However, the roof beam is only affected by one side of the steel plate shear wall and the residual deformation cannot be restored. In order to avoid the failure of the test due to the premature failure of the roof beam, the section of the roof beam is larger [13]. e cross-sectional dimensions of the frame and inner steel plate are shown in Table 1, steel is Q235B, and the test results of mechanical properties are shown in Table 2.…”
