  • Abstract:
  • India is prone to severe earthquakes in the last century. More than fifty per cent area in the country is considered prone to damaging earthquakes. There is nationwide attention to the seismic vulnerability assessment of existing buildings comparatively existing bridges have less attention towards it. However, bridges are essential and critical components of transportation networks in any country. The majority of the Indian bridges were inadequately designed to resist seismic and Wind forces as per outdated building codes. The design shear capacities for short piers is found to be smaller than the corresponding shear demand under condition of flexural over strength. In case of buildings, for high rise structure, as per the structural designer, wind and earthquake load is predominant. As height of building increases it is important to understand the wind profile. In the past, many researchers have carried out wind load analyses including dynamic wind effect on high rise structure. As the height increases, the rigidity and stability of structure gets affected and it becomes necessary to design the structure preferably for lateral forces, moments, story drift and total horizontal deflection at top most story level. There are lots of literatures available to design and analyze the piers. However, the discussion and study about an arrangement and seismic performance of metro bridge pier is not done. The various wind load combinations are applied to a pier of 20 m height located in zone III. The analysis is performed using STAAD-ProV8i software. Axial force, Shear force, bending moment and storey displacement are computed.
