Research on the Restraint of Large-scale Rigid Sample Cracking Test
-
摘要: 本文采用有限元计算和试验测试两种方法对大尺寸刚性试板抗裂性试验的拘束度进行了研究,结果表明,两者的拘束度结果吻合良好。试验焊缝中间的拘束度最大,试验焊缝两端的拘束度最小;局部横向加强筋位置的拘束度大,而远离加强筋逐渐变小。Abstract: The restraint of large-scale rigid sample cracking test is studied through the finite element computation and test in the paper. The simulation results agree well with test results. The results show that the restraint is maximum in the middle of practice weld,is minimum at the both ends of weld,is maximum at the position of strengthening rib,and diminishes gradually at the position away from the strengthening rib.
