Week 8 Challenge
Loading, Analysis and Design Procedure in STAAD Pro
1. Applying Load Exercise
For the structure modelled in previous exercise. Apply following loads
- Form a Load case as DL for Dead Load
- Apply Self weight
- Apply member load of 3 kN/m on the rafter
- Apply member load of 6 kN/m on the secondary beams
- Apply point load of 20 kN at node intersecting inclined member on the top chord.
- Form a Load case as LL for Live Load
- Apply member load of 4 kN/m on the rafter
- Apply member load of 7.5 kN/m on the secondary beams
- Form load combination 1.5DL+1.5LL
MEMBER LOAD 3KN/M ON RAFTER
MEMBER LOAD 6 KN/M ON SECONDARY BEAM

2. Find Maximum Force and Minimum Force for member and present the STAAD result.
Continue previous challenge, Run the analysis and find following results on the member mentioned
- Run the analysis
- Find the Maximum Moment in the Secondary beam for 1.5DL+1.5LL case
- Find the Maximum Axial force on the inclined bracing and identify the member having the maximum force for 1.5DL+1.5LL case
- Identify Bottom chord of Truss having Maximum shear Force & Maximum moment for 1.5DL+1.5LL case and present the values.

4. Design Parameter exercise
In continuation to challenge 1, Apply Design parameter for structure modelled for code IS800:2007.
- Effective Length Lx, Ly, Lz for beams, Truss elements
- Effective length factors Ky, Kz for Columns
- Apply other design parameters for respective members
