چکیده
An experimental study was conducted to investigate the effectiveness of transverse reinforcing bars self-compacting concrete mix (PSCC) and hybrid glass fiber reinforced (HFRSCC) grade M 40 under monotonically increasing axial compression. performed for cylinders enclosed in . The behavior SCC surrounded by a circular ring having different volume ratios clearances compared In this work, we present mathematical model developed predict stress-strain FRSCC constrained unconstrained conditions validate using results. To develop SCC, Nan Su blending method based on filling rate 1.12 1.14, S/A ratio 0.50 0.57 is applied. steel usage mixture assumed be 1% 0.05% respectively. plain mixes glass/steel ratios, stresses, strains, elastic moduli, plasticity ductility unlimited strength ) has been evaluated experimentally. following conclusions can drawn from diagram: 1) Maximum load-bearing capacity strain at peak stress are higher his HFRSCC than PSCC. 2) presence fiberglass increases bearing allows it withstand greater loads loads. 3) If containment form lateral boundary, effect fibers almost negligible. This clearly shows that stronger confinement factor lower HFRSCC, suggesting offers superior with

Comparison of Different Stress-strain Models for Confined Self Compacting Concrete (scc) under Axial Compression
Self Compacting Concrete offers many advantages over conventional concrete. It is mainly used when a great fluidity is required (For example sections with high percentage of reinforcement). Self Compacting Concrete has excellent applicability for elements with complicated shapes and congested reinforcement. An experimental study was made on cylinders and specimens with square sections confined ...
متن کاملStrain and Damage Sensing Property of Self-compacting Concrete Reinforced with Carbon Fibers
Present paper investigated the strain and damage sensing property on concrete cubes embedded with carbon fibers. Concrete cubes of dimension 150 mm have been casted with different concentration of carbon fibers to study the strain and damage sensing property under cyclic loading that can be further used for health monitoring as non-destructive testing (NDT) approach. All the specimens were test...
متن کاملhybrid fiber reinforced self-compacting concrete: hardened properties
in most cases, fiber reinforced self-compacting concrete (frscc) contains only one type of fiber. the use of two or more types of fibers in a suitable combination may potentially not only improve the overal properties of self-compacting concrete, but may also result in performance synergie. the combining of fibers, often called hybridization, is investigated in this paper for a cimentetious mat...
