An Approach for Improving Seismic Behavior of Low-Rise Reinforced Concrete Structural Walls with High Shear |
| Abstract |
Results of an experimental investigation of low-rise reinforced concrete shear walls with rectangular and barbell cross section under cyclic loads are discussed and evaluated. Four half scale models of test specimens with height to length ratio of 0.75 were experimented. The dimension of all walls is 1500mm width x 950 mm height x 100mm thickness for all specimens and the section of all boundary at both ends is 200mm x 200mm.Main variables are : section shape, vertical flexure reinforcement ratios and reinforcement details including crossed diagonal shear reinforcements in SWR2,SW7 specimens. In SWR2 specimen with rectangular cross section, maximum strength and consequently dissipating energy index were 1.59 and 1.21 times greater than those of SWR1 specimen, respectively. In SW7 specimen with barbell cross section, maximum strength and consequently dissipating energy index were 1.28 and 1.48 times greater than those of SW6 specimen, respectively. |
