Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

In the present study, stress-stain behaviour of confined concrete made with nano-silica (nano-SiO 2 ) were taken up. The stress-strain was studied for M30 and M50 grades mixes steel rebars. confinement given in form hoops cylinders, 3 (0.8%), 4 (1.1%), 5 (1.3%) 6 (1.6%). addition along enhanced compressive strength, indicating further effect concrete. It is observed that helpful lower confineme...

Carbon Fiber Reinforced Polymer (CFRP) reinforcement of reinforced concrete (RC) columns has become increasingly common. This work presents a finite element computational model capable representing the structural behavior CFRP-confined square RC columns. Data and results from experimental research available in literature are used to assess ability proposed represent test results. It is possible...

Stress-strain and moment-curvature behavior of the reinforced concrete (RC) square columns have been analytically investigated according to different confined models. The effect transverse reinforcement diameter, spacing grade on RC column models were investigated. For models, confinement effectiveness coefficient, effective lateral confining stress, compressive strength, strain at maximum stre...
