CONSTRUCTION SEQUENCE ANALYSIS OF HIGH-RISE STRUCTURE WITH CREEP AND SHRINKAGE EFFECT
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 …
