Steel And Concrete Roof Structure

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.

Steel and concrete roof structure. Concrete must be reinforced with steel rebar to increase a structure s tensile capacity ductility and elasticity. Singly curved shell and doubly curved shell are the types of shell roofs. When compared to structural steel sometimes twice as fast. In rcc frame the material used is concrete while in steel frame the material used is steel.

The shells roofs are lighter in weight and save reinforcing steel and concrete. Double curved shells are structurally more efficient than single curved shells. The old adage time is money was never more true than when talking about construction schedules. 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.

Type ii this type of building has steel or concrete walls floors and structural framework similar to type i construction. The above illustrations are for composite steel and concrete floor roof or balcony deck systems from the nbs section structural deck systems. The thickness of singly curved shells should not be less than 5 cm. Reinforced concrete is ideally suited for the construction of floor and roof slabs columns and beams in residential and commercial structures.

The steel joists will provide a strong foundation for the flat concrete roofing. This will give it the support it requires. Structural steel is readily available 4. This is indicative of the lod requirements for composite steel and concrete floor roof or balcony deck systems.

01 reinforced concrete framed structure. The roof is also of non combustible material such as concrete or steel. 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.

Less aesthetically minded concrete roofs are common throughout the hurricane prone caribbean islands and parts of the developing world.
