Week 8 Challenge
Q1) Application of loads
Go to general, then loads and definitions. Add all the required loads according to the structure.
- 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.
- 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
Stadd file attached below
Q2) Maximum Force and Minimum Force for member and present the STAAD result.
- Maximum Moment in the Secondary beam for 1.5DL+1.5LL case
- Maximum Axial force on the inclined bracing and identify the member having the maximum force for 1.5DL+1.5LL case
- Bottom chord of Truss having Maximum shear Force & Maximum moment for 1.5DL+1.5LL case and present the values.
Q3)Design Parameter exercise
- Effective Length Lx, Ly, Lz for beams, Truss elements
- Effective length factors Ky, Kz for Columns
