约束边缘区域不同构造的带钢板暗支撑高阻尼混凝土核心筒抗震性能研究
|
摘要
针对带钢板暗支撑高阻尼混凝土核心筒结构,探讨约束边缘区域不同构造措施对其抗震性能的影响,共完成了3个核心筒的低周反复加载试验。试验结果表明:带钢板暗支撑高阻尼混凝土核心筒结构具有良好的变形能力,约束边缘区域配置型钢能提高试件的强度和延性;在角部设置叠合柱的试件,其抗侧刚度和耗能能力有显著提高;带钢板暗支撑高阻尼混凝土核心筒翼墙存在剪力滞后效应,角部叠合柱的设置能降低剪力滞后系数,进一步发挥核心筒的整体空间作用。通过与试验结果的对比与校验,应用OpenSees有限元软件建立高阻尼混凝土带钢板暗支撑组合核心筒试件非线性分析模型,以此非线性分析模型为基础,考察了轴压比对高阻尼带钢板暗支撑混凝土核心筒抗震性能的影响,结果表明即使在试验轴压比为0.6的情况下,这种核心筒的延性与变形指标仍能满足规范要求。
In order to investigate the influence of different structural measures in the confined boundary elements on seismic behavior of high damping concrete core walls with steel plate concealed bracings(HDCW), the cyclic loading tests of three HDCW specimens were conducted. The test results show that, three HDCW specimens have better deformation capacity, the HDCW specimens with shape steel in side columns have larger strength and ductility, the capacity of lateral stiffness and energy dissipation of specimen with steel tube-reinforced concrete corner columns are improved significantly; The HDCW specimens have shear lag effect, and the shear lag factor of HDCW specimen with steel tube-reinforced concrete corner column is smaller and appeared a better global space action. Based on the software OpenSees, the finite element(FE) models of the HDCW specimens are established and verified with the test results. By using the established FE model of the HDCW specimens, the effects of axial compression load ratio on seismic behaviors of the HDCW are examined. The analysis results show that the deformation indices and ductility coefficients of the HDCW could meet the specification requirements even if axial compression load ratio of the HDCW is equal to 0.6.
