摘 要: 利用ANSYS有限元软件分析高厚比对宽翼缘T形钢筋混凝土柱的破坏形态和受力性能的影响。在腹板长度不变,且轴压比相同的情况下,通过改变翼缘长度,设计4组计算模型。分析T形钢筋混凝土异形柱的开裂荷载和极限荷载的变化和裂缝的发展情况,验证柱肢变形由压弯型向剪压型转变的过程。
关 键 词: 混凝土与钢筋混凝土结构;宽肢T形柱;高厚比;非线性有限元;裂缝图

Abstract: Using finite element analysis software-ANSYS, the nonlinear properties of reinforced concrete wide flange T-shaped section columns have been studied including the failure feature and the mechanical behavior under the influence of height-thickness ratio. Four models are designed by changing the length of the flange, while the length of the web and the axial-load ratio are kept invariant. The change of cracking load and ultimate load and the development of cracks of T-shaped reinforced concrete columns are analyzed. The process of transformation of column limb from bend-compression to shear-compression has been validated.
Key words: concrete and reinforced concrete structures; wide limb T-shaped section column; height-thickness ratio; nonlinear finite element analysis; crack propagation figure
