摘要: | Reinforced concrete shear walls are commonly used to resist the actions imposed on buildings due to earthquake loading. To resist such actions, properly proportioned and detailed slender walls are designed to yield in flexure, and to undergo large flexural deformations without loss of lateral load capacity. ACI 318-11 uses displacement-based design to ensure that the shear wall will have adequate deformation capacity. The basis of the approach is to use displacement as the primary design parameter to relate overall system response to wall cross section behavior.
Recent earthquake reconnaissance in Chile and New Zealand gave shocking results for buildings that use a shear wall system. The result indicates that many of these buildings did not have adequate deformation capacity. The typical damage that was found, includes crushing/spalling of concrete, buckling of vertical reinforcement, and global wall buckling. Based on these observations, some changes in the ACI 318-11 will be made related to design and detailing of shear wall for the next ACI series, ACI 318-14. A prototype building which incorporates with two different shear wall cross-sections (rectangular and T-shaped) were chosen to investigate this ACI 318 code change. Design procedures are presented by including the shear capacity design recommended by NEHRP (2011). In addition, the use of high-strength material in the slender walls design was also observed in this study. |
