SEISMIC VULNERABILITY ASSESSMENT OF RC FRAME BUILDINGS USING RAPID VISUAL SCREENING
Earthquake is the sudden shaking of the surface of earth that causes damage to life and property. Damage to man-made structures puts millions of lives at stake in case of an earthquake. Therefore, an effort was made to study the effects of seismic events (i.e. earthquake) on structures. In this work, different types, features and factors affecting seismic performance of structures were examined/discussed in detail.
The basics of faults, seismic waves, magnitude and intensity of earthquakes were studied. The research on different types of structures such as Reinforced Concrete (RC), brick masonry, stone masonry and steel structures were studied in detail in consideration of the seismic safety point of view, which includes the critical structural elements, load distribution path and the effects of the seismic forces on the respective building typology. Various types of load-acting on the structure were also cognized. Critical features affecting the seismic performance of structures (such as pounding, setback, horizontal layout, reentrant corners, soft storey, heavy overhang, short column) were studied, while identification of these features in relation to the respective building type in the real world was also explored.
