2. Structural Analysis & Load Capacities
Structural analysis for 100,000 sq ft Heavy Assembly Plant utilizes 3D space frame modeling in STAAD.Pro and ETABS, incorporating non-linear P-Delta second-order effects. Connection designs utilize high-strength friction-grip (HSFG) ASTM A325 or Grade 8.8 structural bolts pre-tensioned using calibrated torque wrenches.
- Deflection Limit: Main roof beams and rafters limited to L/240 under full service live load, eliminating ponding risks.
- Lateral Drift: Column frames engineered to H/200 drift limits under maximum 50-year return period wind pressure.
- Thermal Expansion: Slotted expansion joint connections integrated at every 60m of continuous length.
