Project 2 - Review of Shear, Moment & Splice connections in StaadPro Connection Module
Design and optimize typical shear, moment and Splice joints in Staad Connection module for the following structure modelled in staadpro. Generate Report.
Design and optimize braced connection (use US standard connections) in RAM Connection.
Structure: A 2D portal frame fixed support spanning 15m with a pitched roof ridge height of 12m with eaves Height of 11.5m. A uniformly distributed load of 10kN/m is applied on the roof beams. Optimize the beams and columns for 85% utilization and consider splice joints at 6m from base and 3m from beam column joints. Consider a hanger beam shear connected with column support of 4m height at 3m from beam-column corner joint carrying 5kN/m vertical load and 5kN horizontal load, hanger beam end is tied with a brace to t
