1 de feb. de 2021 · All the specimens showed a flexural failure mode characterized by the buckling of the vertical steel bars at the boundary elements and concrete crushing at the wall foot. Fig. 7 shows the crack distributions and failure morphology of all the specimens. Download : Download high-res image (844KB) Download : Download full-size image; Fig. 7.
8 de sept. de 2018 · Refer to the below figure Fig. R11.4.1.3 of the ACI 318-14 for the In-plane and out of plane forces in walls. This article will discuss the elements of shear wall design according to ACI 318-14 that categorizes in the following: Factored Axial Force Pu, moment Mu and shear Vu; Wall Shear Reinforcement Requirements; Boundary Elements / Boundary ...
6 de feb. de 2024 · 2.1 CSA S304-14. The maximum axial compressive stress for Moderately Ductile RMSWs and Ductile RMSWs is not explicitly addressed by the CSA S304-14. Instead, the limit is represented in terms of the limitation of the ratio of the depth of neutral axis depth to the length of the wall (\(c/l_{{\text{w}}} \)) to ensure the enough rotational capacity within the plastic hinge region of RMSWs.
1 de may. de 2018 · Two large-scale reinforced concrete walls without ACI 318-14 special boundary elements were tested under constant axial gravity load of 0.053Agfc' combined with reversed-cyclic, quasi-static ...
1 de may. de 2004 · A possible new form of construction employing structural steel as the boundary elements in ductile concrete walls to alleviate congestion of reinforcement in these regions is investigated. The ...

1 de jul. de 2023 · Six shear walls using high-strength concrete and high-strength steels were studied by conducting cyclic load tests, including two reinforced concrete shear walls, and four composite walls reinforced by concrete-filled steel tubes (CFSTs). The effects of steel fibers and boundary element forms on the cyclic behavior of the walls were investigated.
