Time-Dependent Analysis of Shear-Lag Effect in Composite Beams

Journal of Engineering Mechanics, 2001
Taking into account the long-term behavior of the concrete, this paper proposes a model for analyzing the shear-lag effect in composite beams with flexible shear connection. By assuming the slab loss of planarity described by a fixed warping function, the linear kinematics of the composite beam is expressed by means of four unknown functions: the ...

Shear Lag Effects in Steel Tension Members

Engineering Journal, 1993
The non-uniform stress distribution that occurs in a tension member adjacent to a connection, in which all elements of the cross section are not directly connected, is commonly referred to as the shear lag effect. This effect reduces the design strength of the member because the entire cross section is not fully effective at the critical section ...

Shear Lag Effect in Box Girder with Varying Depth

Journal of Structural Engineering, 1988
A finite difference solution is presented for shear lag effect on the box girders with varying depth. The analysis is carried out according to Reissner’s method in which the spanwise displacement is assumed to be a quartic parabolic curve on the cross section instead of a quadratic.

Investigation of shear lag effect in tall tube-type buildings

Structures, 2021
Abstract The dominant structural systems used for high-rise buildings are tube-type systems. Tall tube-type structures act as a cantilever box girder and become prone to the shear lag phenomenon. This phenomenon causes nonlinear stress along the side of the tubular structures, while the beam theory assumes the stress to be linear.

Nonlinear Computation of Shear Lag Effect of Box Beam

2010 International Conference on Artificial Intelligence and Computational Intelligence, 2010
This paper presents an initial value solution of static equilibrium differential equations of thin-walled box beams considering shear lag, shear deformation and geometric nonlinear, which was used to establish the related element stiffness matrix, geometric stiffness matrix and equivalent nodal forces vector.

Shear Lag Effect in Welded Single Angle Tension Member

International Journal of Steel Structures, 2021
The typical failure of a welded single angle tension member is a gross section failure. The rupture strength of the single angle tension member is affected by the effect of shear lag. Full-scale tests on twenty-seven single angle specimens reported in this paper. Four different angle sections with four different section types were used in the test. The

Shear-lag effect in twin-girder composite decks

Steel and Composite Structures, 2003
The paper presents a model for analysing the shear-lag effect on the slab of twin-girder composite decks subjected to static actions, support settlements and concrete shrinkage, which are the main actions of interest in composite bridge design. The proposed model includes concrete creep behaviour and shear connection flexibility.

On shear lag effects in orthotropic composite beams

International Journal of Solids and Structures, 1974
Abstract Based upon the linearised theories of the bending and stretching of thin plates, an analysis is presented for the interaction between non-prismatic beams and an orthotropic concrete plate. It is shown that an exponential representation for the steel beam profiles provides a suitable basis for studying interaction in continuous non-prismatic ...

A flexoelectric actuator model with shear-lag and peel stress effects

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023
Flexoelectric materials are being extensively studied in recent years for potential sensing, actuation, energy harvesting and structural health monitoring applications. However, no analytical model exists in the literature to predict the stress transfer between a flexoelectric transducer and the host structure, considering bonding compliance.

Statistical shear lag model – Unraveling the size effect in hierarchical composites

Acta Biomaterialia, 2015
Numerous experimental and computational studies have established that the hierarchical structures encountered in natural materials, such as the brick-and-mortar structure observed in sea shells, are essential for achieving defect tolerance. Due to this hierarchy, the mechanical properties of natural materials have a different size dependence compared ...
