Agrawal, Ankur (2012) Seismic Evaluation of Institute Building,NIT Rourkela. BTech thesis.
There are many buildings which do not meet the current seismic requirement and suffer extensive damage during the earthquake. In 1960 when the institute building of NIT Rourkela was constructed, the seismic loading was not considered. The building is only deigned to take the dead and live loads. Evaluating the building for seismic conditions gives an idea whether the building is able to resist the earthquake load or not. The objective is to evaluate an existing building for earthquake performance. Firstly preliminary evaluation is done and then detailed evaluation is carried out. For applying earthquake loads, equivalent static lateral force method is used according to IS 1893(Part 1):2002. The Demand Capacity Ratio (DCR) is carried out for beams and columns in order to evaluate the member for seismic loads. Since the reinforcement details of the building were not available as it is more than 50 years old, Design-1 is prepared applying only DEAD and LIVE loads according to IS 456:2000. This helps in estimating the reinforcement present in the building and in assuming that this much reinforcement is present. In Design-2 seismic loads are applied and from this demand obtained from design-2 and capacity from design -1, the DCR is calculated. If demand is more than capacity, the member fails and vice versa. STAAD-Pro V8i is used for loading and designing the building.
