چکیده
Abstract This work aims at describing the behavior of high-strength reinforced concrete (HSRC) beams under short-term ultimate loads with compressive strengths higher than 50 MPa. A plastic approach besides a cross sectional analysis is employed to primarily trace nonlinear response nineteen HSRC simply supported for which experimental results are available. proposed theoretical able acceptably match data minor overestimation flexural moments. Closed-form expressions evaluate ductility indexes regarding deflections and curvatures as well rotation capacities also herein.

It found that member could be increased use high strength concrete. The maximum tension steel ratio guarantee minimum highlighted.

Flexural 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...
متن کاملFlexural Behavior of Reinforced HPFRCC Beams
High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...
متن کاملExperimental Study on Calculation Methods for Short-term Cracks in High-strength Reinforced Concrete Beams
Abstract: High-strength steel has increasingly become widely used among various engineering practices, but the relevant provisions of the codes lag behind its development. Six sets of experiments on simple supported beams reinforced with HTB600 and HTB700 rebars subject to bending loading were conducted in this study to 1) investigate the conditions of crack development, 2) contrast the calcula...
