Experimental and Numerical Investigation on Bending Capacity of Steel- concrete Composite Truss Girder
This article presents an experimental investigation on the bending capacity of steel-concrete composite truss girder (SCCTG). Four full-scale specimens named CB1, CB2a, CB2b and CB3 respectively, are tested and numerical analyzed. Stress distribution, load-displacement relationship, load-slip relationship and ultimate bending capacity of SCCTGs are investigated. The results show that SCCTG foll...
متن کاملBehavior of Steel–Concrete Composite Beams with Corroded Shear Studs Under Negative Bending Moment
The behavior of corroded steel–concrete composite beams under hogging moment was studied by experimental investigation and theoretical analysis. A total of eight specimens, six of which had corroded shear studs, were tested. The corrosion rate of studs ranged from 0 to approximately 50%. The constant-current accelerated corrosion method was adopted to accelerate the corrosion process. The loadi...
متن کاملExperimental study on bending constitutive relation of steel box-concrete combined member
According to the direct homogenization theory of inhomogeneous material, a single medium homogenization constitutive model of the confined concrete in the steel box-concrete combined member has been established, and model parameters have been determined by the measured data of the bending test. By analyzing the theoretical ultimate strength and overall process curve, the results obtained is con...
متن کاملTheoretical and Experimental Study on Natural Frequency of Externally Prestressed Box-Girder with Corrugated Steel Webs
Abstract: Based on the characteristics of box girder with corrugated steel webs, the existing prestressing force, the effect of shear deformation of composite girder on the deflection, “folding effect” in longitudinal direction of corrugate steel webs and the arrangement of external tendons were considered comprehensively. With the experiment results of five literatures integrated, N/fcA (the a...
متن کاملAerodynamic Admittance Research on Wide-body Flat Steel Box Girder
Abstract: Aerodynamic admittance is a key parameter affecting the analysis accuracy of the bridge buffeting response. However, few articles have covered the issue of the wide-body flat box girder with much smaller depth-width ratio (such as 1/12 studied in this paper). Therefore, to explore the real buffeting force of the wide-body flat box girder, experiments of the static force coefficients a...
