摘要

A comprehensive experimental study was conducted on reinforced and steel fibre reinforced concrete (SFRC) continuous composite slabs to quantify crack width resulting from shrinkage and gravity loading. Sixteen full scale slab specimens were cast with different types of interface bond between the concrete slab and steel decking (e.g. greased, unembossed decking or standard decking) and different types and amounts of reinforcement in concrete (e.g. mesh, steel fibre or normal reinforcing bars). Each slab was continuous over the interior support and had a roller support at each end. Concrete shrinkage was measured and serviceability behaviour of slabs was studied over a period of 90 days.
