Comparative Seismic Analysis of Circular RC Slab and Dome Resting Over RC Structure

Earthquake is one of the most destructive of natural hazards. It is the sudden movement of earth cause due to the release of strain energy. About 54% of India’s region is prone to earthquake. Several earthquakes have occurred in India of magnitude 7- 9.1 in last century. Earthquake results in damage structural components of building Roof being tallest component of building is most vulnerable to earthquake as effect of earthquake increases with height. If the roof collapse it is a sudden unavoidable collapse and the people under it may get directly affected and the damage may be so severe that it may not only cause loss of property but also life. Behavior of reinforced concrete domes and circular slab under earthquake loads and the interaction between these domes and the adjoining structure is not well studied due to the scarcity of such structures worldwide. To assess the seismic vulnerability of buildings with domes and circular slab, the dynamic characteristics and behavior of large reinforced concrete domes need to be studied and their susceptibility to damage need to be evaluated.
