摘要: | 本研究主要的目的系藉由实验的方式,模拟钢骨钢筋混凝土柱承受强 烈的地震作用,以探讨其弯矩强度及行为.研究中共制作五组包覆型钢骨钢 筋混凝土柱,其中钢骨采用国内较常使用的十字型与 H 型两种断面型式, 以比较两者之围束效果对韧性能力的影响.箍筋间距亦为参数之一,以了解 箍筋间距不同时,于钢骨钢筋混凝土柱行为上的差异.实验的进行乃以力量 控制的方式施加垂直荷重,并以位移控制的方式施加反覆的水平荷重. 由试验的结果显示:对于钢骨钢筋混凝土柱而言,箍筋间距较密者具有较佳 之韧性能力;而当箍筋间距相同时,十字型的钢骨断面型式其韧性能力较 H 型的钢骨断面型式佳.此外若韧性需求相同时,钢骨断面为十字型的钢骨钢 筋混凝土柱之箍筋间距,可比 H 型的钢骨断面为大.同时发现试体在弹性 行为时,钢骨及钢筋对韧性能力之贡献大致相同,但超过弹性范围时,钢骨 所提供的韧性较钢筋为大.各规范对于钢骨钢筋混凝土柱之挠曲弯矩强度 值皆趋于保守. The major aim of the research is in an experiment to simulate the steelreinforced concrete columns bearing some violent earthquakes in order to examine their moment capacity and seismic behavior.We totally produce fivesets of steel reinforced concrete columns,and the steels commonly adopted in our country are in both shapes of double H and H sections to compare the influence on their confine effects toward ductility capability as well as tounderstand the differences in the behavior of steel reinforced concrete columnswhen the tie spacing is not the same.In process of the experiment,we apply the force vertically by loading control and apply the force repeatedly in displacement control. The result of the experiment shows that as for the steel reinforced concrete columns,the closer the tie spacing is,the better the ductility capability is;however,when the tie spacing is the same,the ductility of thesteel section in a shape of double H is better than that in a shape of H.Besides,if the ductility is required similar,the tie spacing of the steelreinforced concrete columns in a shape of double H is larger than that in a shape of H. Meanwhile,we find that the ductility of steels and rebars isgenerally alike within the elastic range,but over the range, the ductility ofsteels is larger than rebars.Every code to the moment capacity value of thesteel reinforced concrete columns is under limitation. |
