Shear lag in composite box girders of complex cross-sections

A New Approach for Free Vibration Analysis of Thin‐Walled Box Girder Considering Shear Lag Effect

“…where A is the transformation matrix of u * l and δ, which can be obtained on the basis of equations (1), (8), (13), (16), and (24) and B is the transformation matrix of ω * l and δ, which can also be obtained based on equations (1), (10), (13), (21), and (25). e elements of matrix A and B are as follows:…”

“…During the past decades, much effort has been directed towards SLE analysis of the T-WBG. Among these methods [11][12][13][14][15][16][17][18][19][20][21][22][23][24], the energy variation method (EVM) and the FEM are considered to be two of the most widely used methods.…”

A finite segment model for shear lag analysis

“…[1][2][3][4]) on shear lag analysis. The developed methods can be grouped into four: (1) the exact methods based on the folded-plate theory [5], (2) the approximate method based on the bar simulation theory [6,7], (3) the energy method based on the variational principle [8][9][10][11][12], and (4) the finite strip method based on numerical theory [13]. The energy approach has been proven to be a simple and practical method in shear lag analysis [14][15][16][17].…”

Development of a multifunctional photovoltaic integrated insulated concrete sandwich panel

“…This paper represents the keystone for the shear lag analysis due to its simplicity and fairly accurate results. The shear lag model was then generalized to include multi-cellular structures (Evans et al, 1993). Kristek (2004) expanded the harmonic analysis model to account for the partial interaction between the concrete slab and steel box girder.…”
