摘要:

设计了槽式削弱的新型钢填板-螺栓连接,建立多组有限元模型进行数值分析。将新型连接与普通连接在刚度、延性、承载力等方面进行对比分析。考虑开槽个数、开槽边距、开槽长度、削弱高度等因素对梁柱连接性能的影响,采用正交试验设计法确定不同因素组合的模型方案,并用有限元方法探讨各因素对梁柱连接性能的影响程度和影响规律。结果表明:槽式连接的应力与变形主要集中于钢填板,且屈服早于木材的横纹劈裂,连接失效时,钢填板已发生大面积屈服,有效避免了木梁的过早劈裂,并为梁柱连接提供较好的延性; 削弱高度和开槽个数的影响最为显著,增加削弱高度以及开槽个数,使得连接整体屈服更早,而延性增强; 开槽边距增大,连接的承载力提高,但延性减小; 开槽长度对于槽式连接的刚度影响作用有限,但对屈服弯矩和延性系数的影响比较明显。

Abstract:

A new type of connection with weakened slotted-in steel plates was designed, and several groups of finite element models were established for numerical analysis. The stiffness, ductility and bearing capacity of the new connection were compared to the ordinary connection. Considering the influence of the slots' number, edge distance, slot length, weakening height and other factors on the beam-column connection performance, the method of orthogonal design was used to determine the model scheme of different factor combination, and the finite element method was used to explore the influence degree and influence law of each factor on the beam-column connection performance. The results show that the stress and deformation of the connection are mainly concentrated on the steel plate which yields earlier than the cross-grain splitting of the timber. When the connection fails, the steel plate has yielded in a large area, which effectively avoids the premature splitting of the wood beam and provides better ductility for the beam-column connection.The influence of weakening height and the number of slots is the most significant. With the increase of the weakening height and the number of slot, the overall yield of the connection is earlier and the ductility is enhanced. Enlarging edge distance can also increase the bearing capacity, but the ductility decreases. The length of slot has limited influence on the stiffness of this connection, but it has obvious impact on the yield moment and ductility coefficient.
