Analysis on Load Resistance Value of Small Resistance Fastener
摘要
Abstract
Resistance test of fastener under load can verify and improve the calculation theory of longitudinal resistance value of welded fasteners on bridge.It is indicated from test that elastic displacement and longitudinal resistance of small resistance fastener under load are not conforming to the values specified in the document for approval.Under vertical load at each stage, friction coefficient of small resistance fastener can be 0.20 for safety.Longitudinal resistance can be got by vertical load multiplying friction coefficient.关键词
