INVESTIGATION OF CAPACITY ON THE HOLLOW SECTIONS CONNECTIONS WITH STIFFENING PLATE

Buildings behave according to their geometrical types, the profile specifications of static structural elements and the classifications of their materials. This structural behavior is a kind of structural reaction to an earthquake. This reaction may be absorbed by the ductility of the structure. There is an indefinite situation in the description of the level of ductility for a static system in the earthquake occurrence calculation for the moment-shifting steel-frame system that consists of square or circular profile elements. This objective of this manuscript is to overcome local buckling on welded RHS column/beam assemblies and thereby establish a design algorithm. We conducted experimental analysis under the cyclical loads by added rigidity plate having different dimensional parameters to a RHS at the assembly point. We optimized the design and the dimension of the plate with the expansion of the subject models of the experimental analysis by using the Ansys finite-element program.
