Abstract
This study deals with a time-dependent analysis of reinforced concrete G+40 RC frame structures considering the construction sequence with the effect of creep and shrinkage analysis. Because of the non-mechanical deformations induced by the time-dependent deformations of concrete, concrete structures usually present different behaviors when the construction sequences are changed, despite having the same structural configurations. Therefore, the time-dependent effects of concrete such as creep and shrinkage must be taken into consideration to simulate the actual behavior of RC frame structures, in this study considered the static as well as dynamic analysis with the effect of creep and shrinkage analysis. The present work creep and shrinkage analysis is depends on the time dependent approach which is considered the 50 year of life span for that provide the appropriate result for the bending moment, axial shortening, deflection, displacement in structure due to proper load distribution by considering construction in sequence manner as per realistic approach. That time-dependent property is depends on the curing days for the structural elements in the buildings, that curing days considered 28 days according to the floor to floor, due to this consideration that sequential analysis is found out the analysis results according to the time dependent deflection after the 28 days on that particular story level, the 50 year life of span is considered in the staged operation were found out the final deflections and bending moments and that be the actual behavior in the structure after a 50 year of the building construction, that methods of analysis is must be consider for the serviceability criteria.
