Feasibility of Redesigning and Retrofitting of a Structure for Vertical Expansion to Avoid Disasters
The main aim of the study was to find out how the existing building can be further extended to meet the functional requirement, without demolition of the original building by using retrofitting techniques. The existing structure is a residential G+4-storied building of RCC framed structure . In order to find out the structural system of the building, the design was carried out for G+4-storied building with STAAD Pro software, since original design details of the structure were not readily available. Then, redesigning was done for G+7-storied structures to find out the revised details of column and beams mainly. There was a need for retrofitting of the structure to strengthen the structure for the safety of the structure. The scope of work consists of designing/redesigning of the structure to find out the revised section of the structural elements. To determine the requirement of retrofitting of the structure, revised design of structure with increased load was carried out for three additional vertical extensions of building and was find out the overall requirement of retrofitting, to avoid disasters .
