Week 8 Challenge
1.Answer
- going to loading option option in the load case details
- add load such as dead load and live load
- In member load put loads as per given data
- choose Y direction to apply load
- negative sign act as a downward direction
- assign load to selected member as per given data
- for nodal load go to add at Fy point
- assum load to selected nodal points
- for load combination go to load combination option
- selecting dead load ,live load and apply as per given data
2.Answer
- maximum moment for secondary beam 1.5DL + 1.5LL --- 54.26 knM
- maximum axial force for inclined bracing ------------------- 460.245kn
- maximum shear force for bottom chord----------------------263.335kn
- maximum moment for bottom chord ------------------------ 420.855kn
3.Answer
- going to give attachment
- open the model of structure
- after go run analysis option
- choose perform analysis and run the analysis
- see the warning in veiw option
- see the instability in the result layout option
- choose that and fix it
- after all warrnings fixed run the analysis and see the result
- for warning the joints 447 and 451 fix it
- afternthe run analysis we found that there is instability occured
- go to result veiw instability for the points
4.Answer
- going the analysis and design selected steel as material
- select IS-800:2007 code
- define design parameter
- apply it on beam and truss element
- here we take Lx-not applicable
- Ly-as a default use for applying to member
- LZ-as a dedfult use for apply to member
- KY-as a factor take as 1.2 as per IS 800
- KZ-as a factor take as 1.2 as per IS 800
- other parameter such beam apply to selected as 1.0
- Take utility ratio as 1.2 and apply to the structure.
