摘要
为研究部分剪切连接胶合木-混凝土连续组合梁中抗剪连接件不同分布情况对其受力性能的影响,运用ANSYS有限元软件建立4组模型试件,对抗剪连接件进行分段布置,其他相关参数和条件均保持不变,对4组试件的滑移、挠度和剪力进行建模分析。有限元计算结果表明:抗剪连接件分段布置的3组试件滑移和挠度均比沿全梁等间距布置抗剪连接件的试件小,荷载总量相同时对称集中荷载对组合梁滑移和挠度的影响更大;间距为150 mm试件(GCB-4)的抗剪连接件布置方式最合适,该试件的界面滑移和挠度最小,且抗剪连接件的分布方式在实际施工时更方便,只需计算出布置区域并按固定间距布置即可。
In order to study the influence of different distribution conditions of shear joints on the mechanical properties of a partially shear-connected glulam-concrete continuous composite beam,four groups of model specimens were established by using ANSYS finite element software,and the shear joints were arranged in sections.Other relevant parameters and conditions remained unchanged,and the slip,deflection and shear of the four groups of specimens were modeled and analyzed.The finite element calculation results show that the slippage and deflection of the three groups of specimens with shear connectors arranged in sections are smaller than those with shear connectors arranged at equal intervals along the whole beam,and the effect of symmetrical concentrated loads on the slippage and deflection of the composite beam is greater when the total load is the same.The shear connector layout of specimen GCB-4 with 150 mm spacing is the most suitable.The interface slip and deflection of this specimen are the smallest among the several groups of specimens.Moreover,the distribution mode of shear connector is more convenient in actual construction,which only needs to calculate the layout area and arrange it according to the fixed spacing.
