چکیده
This research investigated the flexural behavior of high-strength steel (HSS)—concrete composite beams. The effect concrete strength on load-deflection behavior, capacity, and ductility HSS—concrete beams was investigated. Four full-scale beam specimens were tested under static load. test results demonstrate that failure mode is member compression fracture at mid-span. exhibits good mechanical performance deformation behavior. ultimate bending improved with increased strength. theoretical simplified plastic method overestimates main reason only a small part bottom shows strengthening, which not enough to make up for loss caused by near neutral axis yield relative interface slip. nonlinear based material constitutive model could predict load-bearing capacity accurately. After analyzing 192 sample beams, modified, bearing proposed.

Nonlinear Time-Dependent Behavior of Composite Steel-Concrete Beams
This paper presents a mixed finite element model for the nonlinear time-dependant analysis of composite beams with partial shear connection. The key idea is to consider, as a first approach, a viscoelastic/plastic model for the concrete slab in order to simulate the interaction between the time effects of concrete, such as creep and shrinkage, and the concrete cracking. Creep is taken into acco...
متن کاملFatigue and Overloading Behavior of Steel-Concrete Composite Flexural Members Strengthened with High Modulus CFRP Materials
Due to corrosion and the continuous demand to increase traffic loads, there is a need for an effective system which can be used to repair and/or strengthen steel bridges and structures. This paper describes an experimental program, recently completed, to investigate the fundamental behavior of steel-concrete composite scaled bridge beams strengthened with new high modulus carbon fiber reinforce...
متن کاملFlexural Performance of High-strength Prestressed Concrete-encased Concrete-filled Steel Tube Sections
The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...
متن کاملFlexural Testing of High Strength Reinforced Concrete Beams Strengthened with CFRP Sheets
The objective of this study is to investigate the effectiveness of externally bonded CFRP sheets to increase the flexural strength of reinforced high strength concrete (HSC) beams. Four-point bending flexural tests to complete failure on six concrete beams, strengthened with different layouts of CFRP sheets were conducted. Three-dimensional nonlinear finite element (FE) models were adopted by A...
