Study Notes
Question 1
- Composite trusses or fabricated tapered beams can be used for girders in composite sections
- Both solutions increase the second moment of area of the composite cross-section, aiding in serviceability and ultimate load requirements
- These solutions can be expensive and labor-intensive, needing well-trained technicians for installation
- Methods require careful installation
Question 2
- Controlling floor vibrations is part of structural serviceability
- Increasing composite section stiffness (e.g., by increasing slab thickness, or steel girder stiffness) or adding damping can be used to control vibrations
- Viscoelastic damping materials (VDMs) can effectively reduce floor vibrations
Question 3
- A cost-effective composite connection between steel beams or columns is a practical alternative
- A detailed explanation of this composite connection is available elsewhere
Question 4
- Adding reinforcing steel mesh to the concrete slab in areas where columns and beams connect (particularly in areas where the load is in bending) can improve composite floor systems.
