Abstract:To investigate the compressive behavior, failure mode and ultimate strength of the gusset plate connection contacted with single angle, two full size tests are performed with gusset plate thickness used as test parameters. The finite element analysis by the program ANSYS gives reasonable predictions of the buckling strength of the gusset plate connections, which is consistent with the experimental investigation. Compared the results of the test and finite element simulation with the formula calculated values in the existing steel structure codes domestic and overseas,the applicability of the current standard formula for compressive bearing capacity of such gusset plate contacted with single angle is verifed.
Keywords:gusset plate; compressive behavior; experimental investigation; finite element analysis
