This paper reported the very earliest experimental and analytical studies on bonded Prestressed CFRP tendon enhanced Steel Reinforced Concrete (PSRC) members under eccentric tensile loads . Eight PSRC were tested monotonic loading, three (SRC) simultaneously for comparison. The load–deflection relationship, strain distributions as well crack propagation fracture of concrete investigated experim...

Al2O3 + 30 vol% ZrO2 matrix composites with 20 and cBN have been prepared the optimized processing route, using spark plasma sintering (SPS) at temperatures of 1400 °C 1250 °C. The influence addition on microstructure characteristics, micro/nanohardness, elastic modulus, crack-extension resistance their constitutions investigated scanning electron microscopy (SEM), statistical analyses individu...

Currently, numerous studies have focused on the differences in properties of self-compacting concrete with recycled aggregate (RASCC) and normal (NC), while less attention has been paid to application RASCC reinforced structures. In this paper, four-point bending loading tests were performed seven beams four NC beams, considering parameter reinforcement ratio, flexural analyzed compared. The re...

This paper presents an experimental study on damage assessment of reinforced concrete (RC) beams subjected to incremental cyclic loading. During testing acoustic emissions (AEs) were recorded. The analysis of the AE released was carried out by using parameters relaxation ratio, load ratio and calm ratio. Digital image correlation (DIC) technique and tracking with available MATLAB program were u...

The effect of the temperature variation on a unimorph piezoelectric cantilever is studied. Its influences on the thermal expansion, the piezoelectric constant, the transient part and the creep are experimentally analyzed. Afterwards, a H∞ controller is synthesized in order to reject the thermal disturbance and to reach performances required in micromanipulation. Finally, the closed-loop experim...

The objective of this study is to investigate the flexural behavior M30 grade PSCC, GFRSCC, SFRSCC and HFRSCC beams made with PF=1.12 s/a=0.53 PF=1.14 s/a=0.57 understand effect copper slag as partial replacement fine aggregate on its deflection characteristics cracking behaviour. yield ultimate load taken by optimum PF s/a ratios are higher than conventional RCC beam elements. deflections at c...
