Technical Overview: Advanced Steel Structural System of Hotel
1. Structural System Design
The hotel employs a hybrid steel structure combining moment-resisting frames (MRFs) and braced steel frames to optimize lateral load resistance. Primary load-bearing elements utilize ASTM A992 high-strength steel (Fy = 50 ksi), with H-shaped columns (W14×132) and wide-flange beams (W18×40) designed per AISC 360-22 specifications. Secondary members integrate lightweight CFS (cold-formed steel) trusses for roof spans up to 18m, achieving a dead load reduction of 30% compared to conventional concrete systems.
2. Connection Technology
Critical joints feature slip-critical bolted connections (SCBL) with A325 bolts, ensuring seismic integrity in Zone 4 per ASCE 7-22. Prefabricated steel modules (accuracy: ±2mm) were assembled using robotic welding (AWS D1.8 compliant), reducing on-site labor by 40%. Diagonal eccentric braces (EBFs) with replaceable fuse elements enhance post-earthquake reparability.
3. Construction Innovation
The structure adopted a Design for Manufacture and Assembly (DfMA) approach:
