A Research on Comparison of PT beam and RCC beam for cost and deflection

Abstract

PT not only give the problems beautiful solution, but he also showed us how to build it., Now a days, as architectural demand,structure become more slender and have a very long span ,by RCC we cannot fulfill architecture requirement,in some case RCC also fulfill architecture requirement for a certain span length but after span RCC structure become costly, so it's a research work which structure is economical for post tensioning,for a span, also high labour cost countries is to avoid external scaffolding, for low-rise structures to precast as far as practical and to prestress concrete, not only horizontally, but also vertically so as to resist lateral loads. In most structures today, the increasing use of prestressing has given new freedom to any concept of forms previously considered uneconomic or unfeasible or unduly bulky to resist loads. This research paper is focused on beam design for long span which is used at cinema, multipurpose hole, shopping mole. Pt beam is analysis and design by ADAPT-PT/RC 2015. RCC beam is analysis by STAAD.PRO v8i SS5 and design by manually. Here take beam with two span both span equal length, span of beam 5m to 20m at 3 m interval.
