Experimental study on pull-out mechanical properties of metal anchors for lifting and handling
In order to study pull-out mechanical properties and failure mechanism of metal anchors for lifting and handling(refer to embedded anchor),considering the influence of the borderless and the bordered effects,a set of pull-out device was developed,pull-out test of concrete specimen of embedded anchor was designed and completed.Among them,5 kinds of concrete specimen of embedded anchor were used for affecting by borderless,3 kinds of concrete specimen of embedded anchor were used for affecting by bordered,and ABAQUS was used to simulate the pull-out test of specimens affected by borderless.The results show that pin type,anchor rod type and anchor bar type are broken,the double-ended embedded boom specimens are split,and the anchor plate type embedded sleeve is broken.The concrete conical failure occurs to the concrete embedded suspension with bordered effects.
