Study on tensile behavior of stainless-steel anchor channel assemblies
In order to study the mechanical properties of stainless steel anchor channel components under tension,first,tensile static load tests were conducted on the anchor rod centerline and the mid span position of S-CAG-53/34 and S-CBG-52/34 stainless steel anchor channels.The experimental results showed that the stainless steel anchor channels mainly experienced buckling failure of the channel edge curling.Then,the finite element analysis software ABAQUS was used to establish the finite element models of two kinds of stainless steel anchor channel components.The numerical simulation results were compared with the experimental results to verify the accuracy and applicability of the finite element model.Finally,the finite element model of 50 full-scale specimens was established to study the influence of channel edge thickness,channel side wall thickness,bolt size,bolt spacing and adjacent load on the tensile performance of stainless steel anchor channel components.The analysis results show that increasing the thickness of the channel edge,the thickness of the side wall of the channel and reducing the spacing of the bolts can effectively improve the tensile bearing capacity of the stainless steel anchor channel components.Increasing the thickness of the channel edge and the side wall will increase the stiffness of the channel section,thereby improving the tensile bearing capacity of the middle part of the channel.Reducing the anchor spacing increases the flexural bearing capacity of the channel,thereby improving the tensile bearing capacity of the mid-span of the channel.Changing the length of the anchor rod has little effect on the tensile bearing capacity of the mid-span position of anchor channel,and applying multiple loads simultaneously within a certain spacing results in some anchor rods bearing higher loads,thereby affecting the bearing capacity of the channel.The analysis results show that this effect gradually decreases as the spacing between anchor rods decreases.
