Seismic behaviour of composite structures

Composite structure construction seeks involves the action of two materials i.e., concrete and light-weight steel. This combination has been used in constructing buildings and bridges over many spans.
The earthquake resistance properties of constructed structures include 1. Lower mass & high strength, rigidity and stiffness. 2. High toughness and ductility. and 3. High energy dissipation ability.
The base shear is more in the composite structure of typical low-rise buildings and so it is more vulnerable to an earthquake than the conventional RC building.
Storey drifts and overturning moments are also higher that is 80% and 85% in the case of composite building.
However, results and comparative study observations conclude that composite column design is not suitable when compared to conventional buildings.
