Static Performance and Elastic Buckling Analysis of Stiffened Plates with Flat Flanges
Chengzhong Gui,Junqing Lei,Weiwei Lin,Chaoyi Xia,Zhi Duan 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.5
The present work investigates the static performance and stability of the thin-walled plates with fl at stiff eners under uniform compression. An experiment was fi rst performed to investigate the eff ects of the steel thin-walled box beam-column with intermediate fl at stiff eners on the static performance and stability. The test proved that the external fl ange could enhance the static load-carrying capacity, but the external fl ange’s local buckling predominantly aff ects the members’ buckling performance. The theoretical solution of the stiff ened plates can be focused on improving the buckling performance. The ideal formula for calculating the stiff ened fl ange’s elastic buckling coeffi cient with three simply-supported edges and one stiff ened edge is derived based on the potential energy method. The elastic constraint coeffi cients between the stiff ener and the stiff ened plate are also introduced and fi tted by regression with the 95% confi dence interval’s verifi cation to consider the eff ects of the boundary condition and double-sided arrangement of the stiff eners. The eff ects of the stiff ness ratio between the stiff eners and the stiff ened plates and the geometry parameters of the stiff ened plates and the stiff eners on the buckling coeffi cients have been analyzed. Based on the results, the simplifi ed equations suitable for determining the buckling coeffi cients for the plates with the four simply-supported edges, and the three simply-supported edges, and one free/elastic stiff ened edge, are also suggested. Research shows that the calculating results of the modifi ed equations are in good agreement with that of the fi nite element method, which is also applicable to the stiff ened fl ange without stiff eners.

The effects of the inclination angle on the buckling of continuous composite bridges (CCBs) with parabolic arch ribs remain to be elucidated. Static tests were conducted on an on-site prototype of a CCB with parallel arch ribs to verify the validity of proposed numerical finite element method models of CCBs with inward and outward arch ribs. We found that the expressions for the equivalent slenderness ratios and buckling coefficients should consider the interactions between the in-plane and outof- plane buckling, given the inclination of the arch ribs. With respect to the buckling modes, the arch ribs of all the models buckled in the first lateral mode. In addition, two types of interactions were observed between the buckling modes, namely, that between in-plane and out-of-plane buckling and that between global and local buckling; these were affected by the inclination angle, especially in the case of the CCB with the outward arch ribs.
