摘要:
对古建筑木结构透榫节点的受力机理进行分析，推导了不同松动程度下透榫节点弯矩-转角理论计算公式。为验证理论计算公式的合理性，以6个缩尺比为1/3.2的透榫节点模型试验为对象，其中包括1个连接完好紧密无松动透榫节点和5个连接不紧密有不同松动程度的透榫节点，获得了不同松动程度下透榫节点的弯矩-转角骨架曲线，将理论计算结果与试验结果进行对比分析，两者吻合较好。分析结果表明：随着摩擦系数的增大，透榫节点的转动弯矩和初始转动刚度逐渐增大；增大透榫截面高度，可有效提高透榫节点承载能力；榫头埋置嵌入长度随着木材摩擦系数、榫头插入卯口长度的增大而增加，随着榫头截面高度的增加而减小；随着节点松动程度的增大，透榫节点承载能力逐渐降低。
Abstract:
The mechanical mechanism of t hrough-tenon joints was analyzed, and the moment- rotation calculation formula under d ifferent degree of looseness was deduced. In order to validate the formula, six 1/3.2-scaled t hrough-tenon joints were designed for low cyclic reversed loading test, including a closely joint without loose connection intact and 5 joints with different d egree of looseness. The moment-rotation skeleton curves of the test mortise and tenon joints were obtained and compared with the theoretical ones, show ing that the calculated result s agree well with the test result s. It is also indicated that the rotational moment and initial rotational stiffness increase as the increase of friction coefficients. With the increment of the height of mortise and tenon joints, the load capacity is improved. The e mbedment length will increase with the increment of w ood friction coefficient and insertion length of tenon in mortise, whereas decrease with the increasing of section depth. The loading capacity of through-tenon joints will be reduced with the increase of l ooseness
