“…Thus, the gusset plates, which connect the two BRB ends to the frame, must be properly designed so that they can sustain the maximum axial force capacities developed from the BRBs. The behavior of the gusset plate subjected to tension forces in a steel truss bridge has been studied . For the gusset plate in a steel braced frame, the uniform force method (UFM) has been widely adopted for the gusset plate designs of steel braced frames as it provides a straightforward design procedure to obtain an economical and admissible force distribution .…”

SUMMARY The corner gusset plates in a steel braced frame can be subjected to forces not only from the brace but also from the effects of the frame actions. In this study, several finite element models are constructed to analyze the gusset‐to‐beam and gusset‐to‐column interface forces. It is found that the frame actions affect the gusset interface force distributions significantly. A simplified strut model to represent the gusset plate is adopted to evaluate the frame action forces. In addition, the generalized uniform force method is adopted as it provides more freedom for designers to configure the gusset plate shapes than using the uniform force method. In this paper, a performance‐based design method is proposed. The gusset interface force demands take into account the combined effect of the brace maximum axial force capacity and the peak beam shear possibly developed in the frame. The specimen design and key results of a series of full‐scale three‐story buckling‐restrained braced frame (BRBF) hybrid tests are discussed. The gusset interface cracks observed at inter‐story drift greater than 0.03 radians can be well predicted by using the proposed design method. The BRBF tests and analyses confirm that the proposed design method is reasonable. The effectiveness of varying the width of gusset edge stiffeners in reducing the gusset tip stress concentrations is also investigated. This paper concludes with recommendations for the seismic design of BRBF corner gusset plates. Copyright © 2013 John Wiley & Sons, Ltd.

“…Modelling of connectors (bolts and welds) is usually simplified or neglected. In spite of it this technique is able to pick main features of any stress distribution within gusset plates and thus it is applied pretty often (Crosti, Duthinh 2014;Kasano et al 2012;Kumar et al 2015;Lumpkin et al 2012;Roeder et al 2011).…”

Trussed structures in modern bridge building usually have “W” bracing. Structural joints are often based on application of gusset plates. Experimental tests of stress distribution in such gusset plates are rather sparse. Lab testing of scaled bridge truss girder was carried out in Poznań University of Technology in Poznań. Investigation into stress distribution in gusseted joint was carried out. Test results were put against results obtained from analyses of two finite element models: beam-element model and shell-element model. Normal stress and Huber-Mises equivalent stress distributions within gusseted joint were analysed. General conclusions are: a) normal stress distribution in gusseted joint cross-section, perpendicular to truss flange axis, is nonlinear and extreme stresses occur near cross-section edges, b) Huber-Mises equivalent stress distribution in the cross-section of gusset plate near its connection to truss flange is nonlinear and extreme stresses occur near centre of the cross-section, c) assessment of normal stresses in gusseted joints should not be carried out with an aid of beam-element modelling, d) it is possible to assess Huber-Mises equivalent stresses in gusset plate near its welded connection to rigid flange with an aid of beam-element modelling if non-uniform distribution of shear stress is taken into account, e) shell-element modelling of gusseted joint provides satisfactory accuracy of normal and equivalent stress assessment, f) beam-element modelling of friction grip bolts is sufficiently accurate for shell-element models of steel joints analysed within elastic range of behaviour.

“…A finite-element model of a gusset plate was developed and verified against experimental measurements in ( Crosti and Duthinh., 2014). The design strength equations for gusset plates in the various codes were surveyed and the pertinent strength equations for gusset plates of steel truss bridges were selected by (Kasano et al, 2012). The authors of this study also proposed a pair of strength equations for compression and shear block failure for gusset plates subjected to compressive force.…”

, collapsed, resulting in 13 deaths and 145 injuries. The cause of the collapse was a design flaw resulted in week gusset plate connection. This very tragic example showed us again that, gusset plate design and implementation on bridges have crucial importance. Designers should give significant consideration during the design of steel gusset plate connections. In this study, the buckling behavior of steel gusset plates was investigated. An automated finite-element analysis program (Higgins et al.,2016 ; Scott et al., 2008), was used to analyze the steel gusset plates behavior under compression load. An uniaxial stress strain plasticity model was considered in the analysis. The stress-strain relationship of the steel gusset plates was defined in three dimensions. Nonlinear static analysis of the gusset plates were performed. Different out of plane imperfection, different slenderness ratios, different element sizes were considered during the analysis. The effect of change in the fastener(bolt) location on the steel gusset plates were also examined. Normalization of the ultimate failure loads of the given gusset plate with the critical Euler's buckling load was defined. The variation of this normalization with respect to the change in the steel gusset plate parameters was analyzed. It was obtained that, imperfections have significant effect on the displacement capacity of the steel gusset plates under compression loads.
