Overview

New composite beams and columns were adopted to reduce the beam height and the weight of the columns.

Issue and/or innovation

To reduce the beam height for bigger headroom.
To reduce the weight of the columns.

Reason for composite solution

The height of beam can be reduced by adopting TSC Beam without compromising the design capacity. PSRC system can reduce the column weight compared to typical RC columns.

Specific solution/technical details

Beam: Thin Steel-plate Composite beams (TSC beams)
Column: PSRC Precast Steel-Reinforced Concrete Composite Column (PSRC column)

Impact or effectiveness

TSC beams:
1. A more rigid member (as compared to a long and deep truss) during handling such as dilivery and installation
2. A more uniform surface area for application of cementitious fire-proofing
3. Inceased headroom
4. Connection to column is done in the factory and TSC beams are subsequently bolted on site.
PSRC Column:
1. Column do not require propping
2. PSRC columns comes prefabricated with left in skin-form to facilitate casting
3. Reduced lifting equipment requirements
4. Ease of connection works (bolted construction) for splicing between columns instead of full penetration butt welds
