1. structural steel and composite slab on deck structure form work is minimal. there is no leveling or topping slab required. floor flatness and levelness can be a challenge. due to overload on decking formwork, super-flat floor requirements may be unattainable.
timber vs steel vs concrete structures - sourceable.net . feb 26, 2015 timber, steel and concrete all have their pros and cons. use of precast concrete, which offers great benefits of cost and speed of construction. comprise a steel frame with metal decking, rose 54 per cent worldwide in 2014.
melting snow and water buildup during a rain storm can result in pooling of water on any flat roof, including a concrete roof. trapped water can attract bugs, bacteria, algea, and mold. 2. collected debris and dirt. a roof that is flat, such as a flat concrete roof, is more likely to collect debris that will typically slide off a sloped roof. the homeowner with a flat concrete roof will be required to clean off this kind of debris from his roof more often.
the steel decking profiles are designed to inhibit any longitudinal slip between the steel and concrete in the slab itself, and any transverse movement between the slab and the supporting beams. easy on-site handling. steel decking is transported to site in pre-cut lengths, and in pre-packaged bundles. these bundles can be easily craned into specific work areas, and the individual sheets quickly laid by hand. speedy, safe construction. one advantage of metal deck steel flooring is its speedy
composite slabs. the various shapes provide interlock between steel and concrete decking may also be used to stabilise the beams against lateral torsional buckling during construction. stabilize the building as a whole by acting as a diaphragm to transfer wind loads to the walls and columns temporary construction load usually governs
composite metal deck slab disadvantages composite slabs consist of profiled steel decking with an in-situ reinforced concrete disadvantages of using shot-fired studs or pre-welded studs for beams. the main advantage of composite slab compared to other floors is their quick assembly.
