Elastic Critical Moment of Lateral-Distortional Buckling of Steel-Concrete Composite Beams under Uniform Hogging Moment

International Journal of Structural Stability and Dynamics, 2019
Great attention has been given in the last few years to steel–concrete composite beams due to the gains in strength that can be obtained with the small cost of installing a shear connection between the steel profile and the concrete slab. In continuous and semicontinuous composite beams close to the internal supports, hogging bending moments are ...

Continuous Composite Beams Stiffened with CFRP Sheet at the Hogging Moment Region

2017
The improvement in the flexural response and cracking resistance of steel-concrete composite beams stiffened with Carbon Fiber Reinforced Polymers (CFRP) sheets at the hogging moment regions is investigated experimentally and numerically in this study. The experimental program consists of two composite beams tested in an inverted position to simulate a

The Effects of Partial Shear Connection in Hogging Moment Regions of Composite Beams and Joints

Composite Construction in Steel and Concrete V, 2006
This paper presents the results of an extensive experimental program designed to consider the effects of partial shear connection for beams and joints subjected to hogging moments. The experimental program elucidates some important concepts and highlights the benefits that may be attributable when the use of partial shear connection is invoked.

Fatigue tests on straight steel–concrete composite beams subjected to hogging moment

Journal of Constructional Steel Research, 2013
Abstract This paper describes the fatigue behavior of composite steel and concrete beams subjected to negative bending moment. Fatigue tests with repeated load limited to initial cracking and stabilized cracking, were performed on two steel–concrete composite beam substructures respectively.

Effect of longitudinal reinforcement and prestressing on stiffness of composite beams under hogging moments

Journal of Constructional Steel Research, 2014
Abstract To investigate the stiffness of steel–concrete composite beams subjected to hogging bending moments and their enhancement through prestressing using external tendons, laboratory experiments were conducted on five steel–concrete composite beams.

Experimental study on inelastic mechanical behaviour of composite girders under hogging moment

Journal of Constructional Steel Research, 2010
Abstract Negative bending moments acting on the support regions of continuous composite girders generate tensile stresses in the concrete slab and compressive stresses in the lower steel profile. As a result, the mechanical behaviour of these girders becomes strongly nonlinear, which needs special study.

Behavior of Post-tensioned Steel-Concrete Composite Beams Subjected to Hogging Moments

American Society for Composites 2017, 2017
This study presents a detailed finite element (FE) analysis of the nonlinear flexural response of continuous steel-concrete composite beams strengthened with externally post-tensioned tendons. The initial post-tensioning (PT) force is introduced as an initial strain in the truss element that used to simulate the external tendons. The accuracy of the FE

Mechanical Behavior of Composite Girder with Perfobond Shear Connector under Hogging Moment

Advanced Materials Research, 2012
The mechanical behavior of the support regions for continuous composite girders with tensile stresses in the concrete slab and compressive stresses in the lower steel profile becomes strongly nonlinear under negative bending moments. A static test on four half-scale model of a steel and concrete composite girders with different shear connectors ...
