The large-span constructions, warehouses, and industrial buildings that make use of steel roof trusses do so because of its effective load transfer mechanism and high strength-toweight ratio. Safe and cost-effective designs can only be achieved with precise prediction of structural behavior, including member forces, support responses, and overall structural integrity. The purpose of this research was to use STAAD to model, analyze, and evaluate the performance of a steel roof truss with just one support.Professional Connect Edition. The result is a two-dimensional Pratt truss that uses 45 members and 24 nodes to achieve a span of 15.3 meters and a rise of 1.53 meters. The structure is examined under dead load, live load, and wind uplift scenarios in accordance with the Indian Standard, and all members are first given ISA 20×20×3 equal angle sections. In order to simulate real-world boundary conditions, the numerical model includes a pinned support and a roller support. Load combinations are developed in accordance with the design standards of IS 800:2007, whereas dead load, live load, and wind load scenarios are established according to the guidelines of IS 875. In order to get the nodal displacements, support responses, and member axial forces, linear elastic static analysis is run. Under dead load, the chosen ISA 20×20×3 section deforms excessively, with a maximum vertical displacement of 168.7 mm at the midspan, beyond the acceptable serviceability limit of span/300, according to the findings. Dead load causes the bottom chord's maximum compression force to reach about 60.37 kN, while the combined effects of gravity and other loads bring that force up to roughly 248 kN. Furthermore, the impact of wind uplift is assessed in the research, which leads to a total reversal of the behavior of the member forces when subjected to wind loads alone. According to the results, the original section selection was not feasible and has to be redesigned. For various member groups, we suggest appropriate replacement portions to enhance strength and serviceability performance. Proof that STAAD is effective is provided by the work.For the purpose of computationally analyzing steel truss structures and evaluating structural behavior, we recommend Pro CONNECT Edition.

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.
