Frame Structure | Why Concrete Frame structures are preferred ?

FRAME STRUCTURE

A rigid frame structure is one made up of linear elements, typically beams & columns, which are connected to one another at there ends with joints that don’t allow any relative rotations to occur between the ends of the attached members, although themselves may rotate as unity.

In frame structure, the main loads are transferred to the foundations via the structural frame. The external skin serves to provide wide weather protection and aesthetic quality. The rigid joints that are made between vertical and horizontal members should be rigid enough to enable a framed structure to carry significant lateral loads. This joint rigidity impact a measure of stability against lateral forces.

PREFERENCE OF CONCRETE FRAMED STRUCTURE

Reinforced concrete framed structures are best suited to resist repeated earthquake loading. Repeated earthquake loading which require a high amount of resistance and ductility. Ductility is the ability of structural member to bend in response to earthquake induced forces awhile simultaneously continuing to support the loads it was designed to carry.

• Framed structures have greater flexibility.
• The greater joints rigidity, which enables the frame structure to resist lateral loads, & continuity of concrete frames, gives them more versatility.
• Economical.
• Aestheticism.
