Retrofitting of a Multistoried Building with Earthquake-Resistance Design

Abstract

The predictable growth in economic actions during the twenty-first century is very huge in construction and in transportation. With the increase in population and globalization, there is very less land available for construction purposes; thus, the need of high-rise buildings which are capable enough to resist seismic forces is of much importance. Designing the members of such a high-rise building is being very repetitive and time-consuming, so the concepts of MACROS are widely used for design purposes and can easily eliminate these disadvantages. In this project, the structure is first analyzed by using STAAD Pro and members of the building are designed on the same. Manual calculations were compared with the STAAD Pro results. The structure, which was constructed as G+9, was required to be vertically expanded to G+13. Thereby redesigning and retrofitting measures were taken to modify the structure to withstand increased load.
