Assessing the Behavior of Steel Concrete Composite Columns under Lateral Load | Chapter 7 | Recent Developments in Engineering Research Vol.1

These days, composite areas of the steel and cement have been used and considered the world over, yet filled cylindrical sections require more thought. Wide assessment work has been done in Japan in the latest 15 years on this. This current endeavor shows a preliminary report on the presentation of Concrete Filled steel Tubular segments (CFT). The present research work portrays about implying the use of Concrete Filled steel Tubular segments (CFT) rather than Reinforced Columns and to decide the direct of composite segments. For this reason sixteen quantities of segments with different cross region and distinctive thickness of steel tube (8 short sections and 8 long segments) is exposed to outside pivotal prestress and horizontal burdens. The roundabout and square composite sections are casted with various L/D distribute and divider thickness. The solid utilized is M20. It is seen that Circular composite sections has less redirection and high burden bearing limit with conceded clasping while contrasted with the square composite segments.

Evaluation of Lateral Buckling Phenomenon Using R/C Prisms Detailed with an Ultra High Reinforcement Ratio | Chapter 6 | Emerging Trends in Engineering Research and Technology Vol. 3

The research described in this paper investigates the influence of tensile strain on lateral buckling in reinforced concrete seismic walls having an ultra high longitudinal reinforcement ratio. The present work is experimental. In the framework of the present research, 5 test column specimens of scale 1:3 simulating the extreme areas of ultra highly reinforced concrete walls were used. The test columns are of identical proportions and reinforcement content, with the only variable being the applied load history. All specimens were reinforced with the same ultra high longitudinal reinforcement ratio (6.03%) which was bigger than the maximum value prescribed by Codes. This was done deliberately for experimental reasons. The degree of tensile strain which was applied was different for each specimen and it took values equal to 0‰, 10‰, 20‰, 30‰ and 50‰. The present paper tries to investigate the influence of the degree of tensile strain to the ultimate bearing capacity of test specimens. Based on the results, it is apparent that the amount of tensile strain that reinforcing bars within the extreme areas of concrete walls are subjected to directly affects the buckling phenomena upon reversal of loading.
