EXAMINING THE G+2 REINFORCED CONCRETE FRAME'S STRUCTURE USING STAAD.PRO

Abstract

Reinforced concrete (RC) frame structures must undergo structural analysis as a first stage in their design to guarantee sufficient strength, stability, and serviceability when subjected to stresses. Engineers may now more efficiently and accurately model and analyze complicated structural systems in three dimensions because to advancements in structural analysis software. This research project details the STAAD-based structural analysis of a G+2 reinforced concrete frame. Professional V8i (SELECTseries 5) in action. Following the applicable Indian Standard standards, a three-dimensional analytical model was created with 87 structural members and 48 joints. The model accounted for the necessary material qualities, sectional dimensions, support conditions, and loads. All loads, whether dead or live, as well as the governing load combination of 1.5(DL + LL), were taken into account throughout the study. Support responses, bending moment, shear force, axial force, and vertical displacement were used to analyze the structural response. Selected STAAD results were used to confirm the computational model's correctness.Simplified manual computations grounded on classical structural analysis techniques were contrasted with Pro. The numerical model was shown reliable when the comparison revealed variances within acceptable engineering norms, with a maximum divergence of around 12%. All structural response characteristics fulfilled the serviceability standards defined in IS 456:2000, according to the study. According to the research, STAAD.Pro is a solid and efficient platform for conducting 3D analyses of reinforced concrete frame structures, which may greatly aid in engineering and structural design decisions.
