Abstract
The design process of determining the optimal number of floors that may be added to an existing high rise building structure requires the thorough analysis of several important components. Various obstacles need to be considered when determining the addition of these floors. It is of high importance to evaluate how the addition of floors will affect the dead, live, wind, and seismic loading parameters of the building. Moreover, the loading capacity of the geotechnical soil properties, the existing footing, columns, shear walls, and beams in the initial design of the building need to be thoroughly analyzed. The aforementioned steps must be completed to ensure the building is as safe and economically feasible as possible. The addition of floors to an existing building design can add strain and stress to the structural components of the building and, therefore; need to be monitored. Implementing a health monitoring system in this high rise building would be very beneficial in detecting early damage to the structure. The health monitoring system will allow one to monitor, control and address any structural deficiencies before significant failure occurs. The monitoring strategy will include shrinkage, swelling, strain, deflection and creep. With the use of fiber optic sensors and external sensors, the building can be monitored to ensure that stresses and strains are recorded over the lifespan of the building. The main focus is to ensure that the building remains safe throughout its lifespan and allows owners to feel more assured in the safety of their building.
