Influence of constructional details on the load carrying capacity of beams

Lateral–torsional buckling resistance of coped beams

“…According to previous research [1][2][3][4][5][6][7][8][9], the influence of the cope increases with increasing depth to span ratio. Therefore, most calculations were carried out on relatively stocky beams.…”

“…The ultimate buckling resistance is obtained by multiplication of the crosssectional capacity with the buckling factor, Eq. (8). For the sections considered, this crosssectional capacity is equal to the plastic moment resistance.…”

Beams

“…End connections such as partial end plates (Lindner, 1985) and coped ends (Yura and Cheng, 1985;Lindner, 1994) can influence the LTB resistance substantially. The influence of end copes should be considered when the depth of a cope is greater than or equal to 0.2d , where d is the total depth of the cross section.…”

Development and validation of a numerical model for buckling of coped beams

“…du Plessis [2], Cheng and Yura [9], and Lindner [10][11][12][13][14] carried out full-scale tests on coped beams for determination of the buckling resistance. These tests were carried out with connections to main beams as applied in practice, resulting in partial restraints to rotation about the weak and strong axes of the beam supports.…”
