| 摘 要： | 在混凝土等级、截面配筋率、轴压比和墙肢截面高厚比取得优化值的基础上以及总配筋量不变的情况下,对常规、加暗柱和加暗支撑3种T形短肢剪力墙进行了3组弹塑性有限元分析.分析了改变暗柱和暗支撑的配筋率对加暗柱和加暗支撑的T形短肢墙变形及延性的影响,并对其进行比较优化.结果表明：暗柱和加暗支撑的配筋率分别为2%、2.2%时,变形及延性等综合性能较好,加暗支撑T形短肢墙综合性能优于常规和加暗柱T形短肢墙. |

| Abstract: | According to finite element theory and computer simulation principle mentality, in concrete grade, sectional reinforcement ratio, axial compression ratio and sectional depth-thickness ratio having obtained the optimized value and the total reinforcing quantity invariable situation, the three groups stress-strain finite element analyses of three kinds of T-shaped shot-leg shear walls with conventional, concealed column and concealed bracings, are carried out. The influences of the reinforcement ratios of concealed column and concealed bracings on the deformation and ductility of T-shaped shot-leg shear walls with concealed column and concealed bracings are analyzed; and then it is comparied and optimized for them. The results indicate that when the reinforcement ratios of concealed column and concealed bracings respectively are 2 %, 2.2 % , comprehensive performance about deformation, ductility, etc. is better. Comprehensive performance of T-shaped shotleg shear wall with concealed bracings is superior to the conventional and with the concealed column. |
