Gravity and Lateral analysis (Notional/Wind/Seismic) |
“Beam & Slab” buildings |
Flat slab and “Beam & Slab” buildings |
| Special Features |
- Pattern loading
- Automatic EC2 sway sensitivity assessment and sway amplification
- Automatically centralised analysis wires (improved rigid offsets / rigid zones)
- Option to mesh slabs in the 3D analysis
|
- Mimics traditional design approach (sub-frame analysis)
- Pattern loading
|
- Mimics traditional design approach (isolated floor analysis)
- Slab Pattern loading
|
| Benefits |
- Member Design considers sway and differential axial deformation effects.
- Caters for slabs that contribute to the lateral load resisting system
|
Member design based on traditional sub frame is considered simultaneously with that for 3D Analysis |
- Member design based on traditional sub frame is considered simultaneously with that for 3D Analysis
- Irregular slab panel design automatically catered for
|
| Analysis Model |
3D model of entire building:
- either meshed 2-way slabs,
- or, slab loads decomposed to beams
|
series of 3D sub models:
- all column and wall stacks immediately above and below the sub-model
- either meshed 2-way slabs,
- or, slab loads decomposed to beams
|
series of 3D sub models:
- all column and wall stacks immediately above and below the sub-model
- all 2-way slabs meshed
|
| Analysis Method |
Whole model in one pass |
Each sub model sequentially from top to bottom – chasing member loads down |
