Abstrakt:

Brackets are used to transfer loads in steel structures where the load is offset from the support. This paper will focus on T‐shaped brackets. Although such bracket plates are often used, a reliable design guideline is missing. Several design methods are presented and their accuracy is evaluated. Details of 86 experimental specimens from four previous research projects were compiled. Numerical models of these specimens were created, linear buckling analysis (LBA) and materially nonlinear analysis (MNA) were performed to determine the buckling force and inelastic strength, respectively. Both analyses are simple to use, robust and fast‐to‐converge methods. The purpose of this research was to develop practical design guidelines for the buckling strength of bracket plates that can be implemented with LBA/MNA. Investigated triangular bracket plates are supported on two sides, the legs, and free at one side, the hypotenuse. Buckling curve for this case is unknown. A reliability analysis is presented for the determination of critical load multiplier to avoid buckling. The results of MNA, which disregards buckling, can be safely used when the critical load multiplier, based on LBA, is equal to or greater than 4.
