| 摘 要： | 拼接板厚度是高强螺栓摩擦型连接中的一个重要参数.采用有限元分析方法,同时考虑材料、几何和接触状态3个非线性,对框架结构中钢梁高强螺栓拼接采用不同拼接板厚度时的性能,进行单调和循环荷载作用下的模拟研究.结果表明:采用较薄的拼接板时,试件的拼接区滑移出现得早,拼接板的塑性屈曲变形也变大;在设计中加大拼接板的厚度则不会对拼接区的性能造成明显影响.

| Abstract: | The thickness of splice plates is an important factor in frictional connection with high-strength bolts.Using finite element method and taking into consideration the three nonlinearities of materials,geometry and contact conditions,the modeling of high-strength bolted beam splices in framed structure was performed under both mono-and cyclic-loading onto the splice plates with different thickness.The result showed that slipping of faying surfaces occurred earlier when using thinner splice plates,and the plas... |
