摘要(中)

此研究利用LS-DYNA建立預鑄鋼筋混凝土的梁柱接頭，並以單一載重與循環剪力載重模擬破壞行為，其結果要與實驗數據對比(Psycaris和Mouzakis 2012)。於梁柱接頭置入兩個植筋以抵抗剪力強度，同時梁柱之間的混凝土也放置一層橡膠。理論上，影響握裹力的是抗剪強度。材料特性和接觸參數已從混凝土抗壓試驗、鋼筋抗拉試驗、握裹試驗驗證得知，以及表面接觸的驗證結果在模擬中是合理的。其中，以MAT_CONCRETE_DEMAGE_REL3和MAT_PLASTIC_KINEMATIC建構非線性材料，橡膠則是彈性材料。梁、柱與橡膠利用八個節點建立實體元素，而植筋、鋼骨與箍筋以非線性行為建立構架元素。橡膠與混凝土之間的表面接觸以CONTACT_AUTOMATIC_SURFACE_TO_SURFACE模擬，而植筋與混凝土之間的接觸元素以CONTACT_1D建構在LS-DYNA的平滑連續模型。兩個試樣分別以─力控制的單一荷載與位移控制的循環剪力荷載模擬中，其結果與實驗數據的剪切位移關係相似。基於分析和討論下，以LS-DYNA的有限元素程式在兩種荷載模擬的梁柱接合行為中，探討有關剪力位移、插筋作用與其中的應力關係，是否與理論和實驗數據符合。

摘要(英)

Failure simulation using LS-DYNA of precast reinforced concrete beam-to-column connection under monotonic and cyclic shear loading is proposed. The experiment data to be simulated was taken from Psycaris and Mouzakis (2012). Two dowel bar as a device to resist shear loading is placed across joint. A rubber is also placed between the column and beam concrete. Influence of pull out resistance in shear resistance is explained by theory. The validation of material properties and contact parameter had been conducted by simulation compression test of concrete, a tensile test of steel, pull out test between steel and concrete, and validation of contact surface which the result is acceptable to be used in the simulation. Nonlinear material models of the concrete and steel such as MAT_CONCRETE_DEMAGE_REL3 and MAT_PLASTIC_KINEMATIC are considered. The rubber is considered using the elastic material. Solids element with eight-node element is used to build the beam, column, and rubber. Frame element is to simulate nonlinear responses of the dowel, reinforced steel, and stirrup. The contact surface between rubber and concrete is simulated by CONTACT_AUTOMATIC_SURFACE_TO_SURFACE. Contact element between concrete and dowel is constructed by CONTACT_1D as bond slip model of solid and frame element at LS-DYNA. Two specimens simulation with different coefficient of pull out resistance is simulated under monotonic loading which one of both specimens that have the closest shear-displacement relationship with experiment result is chosen to conduct under cyclic loading. Force control is used in monotonic loading and displacement control is used in cyclic loading. The behavior of connection under monotonic and cyclic loading is investigated by shear-displacement result, dowel action, stress at concrete and dowel and crack propagation which match with theory and experiment result. Based on analysis and discussion, the behavior of connection under shear loading can be investigated by the numerical method using LS-DYNA finite element program.
