Study Notes
Composite Floor System Design
-
Long Span Solutions: Composite trusses or fabricated tapered beams are used as girders for spans exceeding 16 meters. These options improve stiffness and strength , but have higher material costs and require skilled labor for installation.
-
Vibration Reduction: Increasing the concrete slab thickness and using stiffer steel girders/beams increases the composite floor system's stiffness. Adding viscoelastic damping materials (VDM) absorbs vibrations, improving occupant comfort. This relates to the serviceability requirements in the system's dynamic performance.
-
Column Connection Design: Composite connections between steel beams (like Universal Beams) and columns (like Universal Columns or composite columns) are cost-effective and practical. Design details for composite columns should address the concrete-filled hollow sections, ensuring proper load transfer and connection stability. Bolts, shear studs, and reinforcement are key elements of these connections.
-
Hogging Region Cracking: Additional steel reinforcement (like steel mesh) placed on top of the concrete slab in hogging regions (where beams connect to columns) prevents cracking from high tensile stress. This reinforcement enhances the durability and maintainability of the system.
Key Engineering Concepts
-
Structural Integrity: Long-span composite systems use trusses and tapered beams to distribute loads effectively.
-
Serviceability: Damping materials are used to reduce vibrations for improved occupant comfort.
-
Practical Connections: Composite connections between beams and columns offer cost-effective solutions.
-
Durability: Reinforcement in areas like hogging regions reduces cracking for longer system life.
