摘要
为研究空心胶合木-钢插板螺栓连接节点承载力及延性性能,探讨了不同胶合木宽度和螺栓直径对破坏模式的影响,分析了不同宽径比、承压宽度对节点承载力、延性等的影响。结果表明:增加宽径比及承压宽度,可有效提高节点延性。宽径比12.5~16.4的节点延性较佳;宽径比10.0~10.9是单、双塑性铰破坏模式的临界点,可作为工程设计参考值。
In order to study of bearing capacity and ductile performance of hollow glued-laminated timber and slotted-in steel plates bolted node, the influence of different ratio of bolt diameters and bearing widths on failure modes was discussed. The influences of different width-diameter ratio and bearing width on bearing capacity and ductile performance were analyzed. The results indicated that the ductile performance could be effectively improved by increasing the width-diameter ratio and bearing width. The node was optimal in ductile performance with the width-diameter ratio of 12.5~16.4. The width-diameter ratio of 10.0~10.9 is the critical point of single and double plastic hinge failure mode, which can be used as a reference for engineering design.
