Steel And Concrete Roof Structure

The above illustrations are for composite steel and concrete floor roof or balcony deck systems from the nbs section structural deck systems.

Steel and concrete roof structure.

This is indicative of the lod requirements for composite steel and concrete floor roof or balcony deck systems. The old adage time is money was never more true than when talking about construction schedules. Concrete must be reinforced with steel rebar to increase a structure s tensile capacity ductility and elasticity. Double curved shells are structurally more efficient than single curved shells.

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

When compared to structural steel sometimes twice as fast. As the width of the concrete slab is 16 3 4 inches place the steel joists at this distance. These structures often consist of small cinderblock homes topped with rows of steel beams and blocks that are covered in a coat of concrete. The bottom of the joists should rest on either a beam or a wall.

According to gerosa buildings with concrete can almost always be built faster. The steel joists will provide a strong foundation for the flat concrete roofing. 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. The thickness of singly curved shells should not be less than 5 cm.

Type ii this type of building has steel or concrete walls floors and structural framework similar to type i construction. In rcc frame the material used is concrete while in steel frame the material used is steel. Structural steel is readily available 4. Reinforced concrete is ideally suited for the construction of floor and roof slabs columns and beams in residential and commercial structures.

Singly curved shell and doubly curved shell are the types of shell roofs.
