ANALYTICAL STUDY OF THE BEARING CAPACITY FOR DOWEL-TYPE CONNECTIONS IN GLUED TIMBER WITH SLOTTED STEEL PLATES BASED ON THE BEAM ON ELASTIC FOUNDATION

在木结构工程中钢填板销连接节点是常见的节点连接形式,为便于木结构的设计分别进行了销槽承压试验和钢填板销连接承载力试验,提出了基于弹性地基梁计算方法的钢填板销连接承载力计算式。试验和计算结果表明:荷载作用下钢填板销连接节点有三种屈服模式,与GB 50005—2017《木结构设计标准》中的屈服模式相吻合,并且屈服模式可通过计算预估;运用所提出的钢填板销连接承载力计算式所得出的计算结果与试验结果基本吻合。

The dowel-type connection in timber structures with slotted steel plates is a common connection in timber structure engineering,in order to facilitate the design of the timber structure engineering,compression tests of the timber dowel groove and dowel-type connection in glued timber with slotted steel plates were conducted respectively.The results indicated that there were three yield modes of dowel-type connections in timber structures with slotted steel plates under loads,which were consistent with the yield modes in Standard for Design of Timber Structures(GB 50005-2017),and the yield modes could be predicted by calculations.The experimental results showed that the calculation results obtained by the proposed calculation formula for the bearing capacity of the dowel-type connection in timber structures with slotted steel plates were basically in agreement with the test results.
