A total of four specimens have been tested with different edge distances and spacings in order to study the failure of chemical anchor bolt anchorage group subjected to shearing strength.The influence of different edge distances and spacings on the failure form,shearing strength and ultimate displacement is taken into account by the whole variety test of failure load and the results of finite element.The results indicate that the edge distance has impact on the failure form and displacement of chemical anchor bolt anchorage group under load.Brittle fracture may occur under the condition of small edge distance while ductile fracture may occur under the condition of large edge distance.In addition,the spacing has impact on the interaction of chemical anchor bolts.The test indicates that the stress generated by the interaction of anchors with small spacing will result in the propagation of crack along the depth of anchor.When the stress generated with the row of anchor bolts is independent of each other under the condition of large spacing,cracks form two separate concrete wedges.Comparison of the test data with finite element analysis result shows that the equation provided by the related code is reliable in shearing strength.
