Gravity Load Support System
• Steel Deck with concrete topping
• Inclined Beams• Columns• Foundation
Lateral Load Support System
• Braces in multiple direction in west side, only lateral bracing in east side
• Concentric
• W- sections
• Round HSS
W- section Braces Round HSS Braces
Lateral Load Support System
• Better performance in buckling load• Larger radius of gyration reducing the
slender ratio
Horizontal Stability
• Concreted Steel sheet as rigid floor diaphragm
• Horizontal stiffener beams to support columns and beams laterally
Yellow – Load carrying Beam
Blue – Columns
Red – Lateral Stiffener Beams
Lateral Torsional Buckling
• Local Torsional Buckling of member
• occurs due to buckling of compression flange
Connection Details
• Steel deck sheet to beams
• Seat Type Connection
• Welded
• Bearing Length = 2.5”
Connection Details
• Brace Connections
• W-shapes• Bolted to gusset plate
• Gusset Plate Connection• Beam interface- Welded
• Column interface - Bolted
Connection Details
• Brace Connections
• Round HSS • Slit and welded to gusset plate
• Longitudinal Weld all around
• No augmentation
• Gusset Plate Connection• Beam interface- Welded
• Column interface - Bolted
Connection Details
• Beam to Concrete
• Seat Type to Concrete column
• Web stiffener right above the connection
• Embedded Plate Connection to Wall
• Shear transfer from beam to concrete wall
Connection Details
• Beam Splice Connection
• Web only connected but not flange
• Bolted to one beam and shop welded to the other for easy fabrication
• Web stiffener to prevent web crippling

Connection Details
• Column to foundation
• Column welded to base plate – fillet weld all around
• Base Plate anchored to the foundation
• Base plate designed for uplift of the column being an open structure
