Effect of Shear Lag on Buckling of FRP Box-Beams
2018Nowadays, FRP applications have been increased in the various engineering fields because of their numerous mechanical and physical properties, i.e., high strength, lightweight, corrosion resistance, and tailoring ability. The tailoring ability of FRP gives us flexibility to change the configuration and positions of fiber orientation in the laminate; it

A simplified method for the determination of the effective width due to shear lag effects
Journal of Constructional Steel Research, 1993Abstract While it is usually assumed in bending theory that plane sections remain plane after loading, this assumption does not hold for short span beams with wide flanges. Shear lag effects cause the stress distribution over the cross-section to be non-linear.

A hand calculation of the shear lag effect in stiffened flange plates
Journal of Constructional Steel Research, 1984Abstract A method of analysis is presented which enables the effects of shear lag in steel box girders with heavily stiffened flanges to be taken into account quickly and conveniently using hand calculations. The method idealizes the flange as a system of axial load-carrying bar members and shear-carrying sheet members and employs harmonic analysis ...

Shear Lag Analysis and Effective Width of Curved Girder Bridges
Journal of Engineering Mechanics, 1985The effective width of curved girder bridges is formulated by substituting the flange stress derived from present theory into the equation of effective width definition for the curved girders. The required information in formulating the effective width rule for design of curved girder bridges are provided.

Formulas for Shear‐Lag Effect of T‐, I‐ and Box Beams
Journal of Structural Engineering, 1990Based on an empirical matching of analytical results for stresses in wide flanges obtained using the plane stress elasticity given by Song, simplified empirical formulas and some diagrams for the determination of the shear-lag effect in simple beams under various loading with I, and box cross sections are presented.

Effect of Skewness on Shear Lag Effect in RC Box-Girder Bridges
2018This paper deals with 3-D linear elastic finite element analysis of box-girder bridges to study the influence of skewness on the longitudinal stresses and shear lag effect in simply supported box-girder bridges. In the present study, a 20 m span simply supported box-girder bridge with different degrees of skewness varying from 10 to 60° has been ...

Effective number of mega-bracing, in order to minimize shear lag
Structural Engineering and Mechanics, 2013In this paper, influence of geometric configurations of multi-story bracing on shear lag behaviour of braced tube structures is investigated. The shear lag of 24-, 36- and 72-story braced tube structures are assessed considering all possible configurations of overall X and Chevron bracing types.

Shear Lag Effect in Single Plane Cable-Stayed Bridge
Advances in Structural Engineering, 1998The shear lag effect in thin-walled trapezoidal box sections with inclined stiffeners within the cell is analyzed using the principle of minimum potential energy. Due to the combined action of axial force and moment in a cable-stayed bridge, the normal stress in the pylon is given by [Formula: see text]. The coefficient of shear lag can be written as [
