While designing any type of structure some parameters may influence the design of the structure. This project evaluating the influence of different parameters in the design of steel structures. To find out the influencing parameters involves the analysis of simple 3-D frames by using a very popular software tool STAAD Pro.On this calculated all necessary loads and load combinations and applied all loads, and compared the results with software tool STAAD Pro. And manually calculated results. Detailing the material properties, like a different grade of steel, and compared the results. Compared...
