摘要
抗滑移系数是高强螺栓摩擦型连接中的一个重要参数。本文对框架中高强螺栓拼接采用不同抗滑移系数时的性能,以及接触面的抗滑移系数大于和小于设计值时的性能,进行了单调荷载和循环荷载作用下的研究。结论表明:采用不同抗滑移系数设计的拼接节点,其性能差别很小,在设计时可不予考虑;接触面抗滑移系数大于或小于设计值,将直接导致拼接区的滑移出现和耗能性能的不同,但对拼接的极限承载能力并无影响。
Slipping coefficient （SC） is an important factor in high-strength bolt slip-critical connection. The modeling of high-strength bolt splice in frame structure under both mono- and cyclic-loading, with different SC and SC higher or lower than designed value, is studied. Results show that performance of splice joints with different SC differ very lightly, while SC higher or lower than designed value will lead directly to different slipping appearing time and energy-dissipation, but do not affect the ultimate load- carrying capacity of splice joint.
