| dc.description.abstract | In the current scenario of ever-increasing incidence of earthquakes around the world, we need to carry out a macro level study and review the causes of earthquakes and consequential effects of it and identification at Source and tracking it to the Society. Natural calamities cause severe and more often than not, indescribable suffering, loss of lives and livelihood, destruction of houses, properties, infrastructural installations and facilities, separation of humans and great many other losses. Thus the implications are multifaceted involving economic hardships, human sufferings and a great deal of severely adverse social effects. For ascertaining the structure responsiveness and resistance to earthquakes, the source/ path parameters and site features need to be studied and depicted scientifically to assess the geophysical as well as seismological effects. The buildings which were designed and constructed according to the old codes may not satisfy the requirements of the presently used seismic codes and design practices. Therefore, it is crucial to reassess the codes to prevent economic loss and loss to human life and property caused during earthquakes. Buildings damaged in the past earthquakes or the existing buildings deficient to resist seismic forces need to be retrofitted for better performance in future earthquakes. Seismic evaluation is the first step before retrofitting procedures to determine the most exposed and vulnerable members and deficiencies in a structure in order to protect them during an event of an unexpected earthquake. The seismic retrofit/rehabilitation procedure intents to enhance seismic performance of the structure and rectify the insufficiencies by enhancing stiffness, strength or deformation capacity and also improves connections. The present study deals with the seismic retrofitting of two structures located in diverse seismic zones. Each structure is retrofitted under two different schemes and the results are compared to find out a better method of retrofitting for both structures. After the analysis, the results were compared under time periods, base shear, and modal participating mass ratios, bending moments and shear forces for all beams and moment capacities and axial forces for all columns and were found satisfactory to withstand the design earthquake forces and results are tabulated in the report. | en_US |
