Steel And Concrete Roof Structure

01 reinforced concrete framed structure.

Steel and concrete roof structure.

Reinforced concrete is ideally suited for the construction of floor and roof slabs columns and beams in residential and commercial structures. Less aesthetically minded concrete roofs are common throughout the hurricane prone caribbean islands and parts of the developing world. Structural steel is readily available 4. The present trend is to adopt reinforced concrete for bridges of small medium and long spans resulting in aesthetically superior and economical structures in comparison with steel bridges.

According to gerosa buildings with concrete can almost always be built faster. This will give it the support it requires. The old adage time is money was never more true than when talking about construction schedules. The above illustrations are for composite steel and concrete floor roof or balcony deck systems from the nbs section structural deck systems.

When compared to structural steel sometimes twice as fast. This is indicative of the lod requirements for composite steel and concrete floor roof or balcony deck systems. Concrete must be reinforced with steel rebar to increase a structure s tensile capacity ductility and elasticity. In rcc frame the material used is concrete while in steel frame the material used is steel.

The steel joists will provide a strong foundation for the flat concrete roofing. The thickness of singly curved shells should not be less than 5 cm. Double curved shells are structurally more efficient than single curved shells. Singly curved shell and doubly curved shell are the types of shell roofs.

The bottom of the joists should rest on either a beam or a wall. As the width of the concrete slab is 16 3 4 inches place the steel joists at this distance. Reinforced concrete and steel frame structure structural system has the same load transfer method but the difference is in the material from which its members are made i e. However the roof covering material is combustible.

The roof is also of non combustible material such as concrete or steel.
