Structural system yielding minimum differences between ordinary and staged analyses

Abstract Structural engineers should appropriately design concrete structures to resist lateral loads. Determining the adequate system for resisting expected loads is important control building drift. Choosing appropriate usually conducted assuming predicted forces are applied completed buildings at one step which commonly known as ordinary analysis ( OA ). Nevertheless, these constructed sequentially requires using staged SA ) instead of . In this paper, a comprehensive numerical model buildings, accounts time dependent effects, utilized well-validated commercial software. Six reinforced with 10 and 20 storeys analyzed developed model. Three various structural systems considered (Rigid Frame RF ), Shear Wall SW WF A comparison between displacements internal in beams slabs obtained from For 10-storeys building, maximum bending moment 29.9% higher than that The same conclusion was observed shearing force percentage 19.6%. Moreover, moments 20-storeys are, respectively, 35.0% 23.5% larger those provided minimum difference differential displacement analyses. produced least differences all studied buildings.
