High-rises are buildings that are 15m or above in height, irrespective of their occupancy as per the National Building Code of India. Other terms used for high-rise buildings are multi-storeyed buildings, tall buildings, and skyscrapers. A skyscraper has multiple floors of the order of 100 meters height or more, which make it a very high-rise building.
High-rise buildings are the outcome of technological innovations in engineering and material development. Technolo- gical advancements in structural systems, design, formwork, construction methods, elevators, lighting, heat and ventilation systems, building materials, energy efficiency, software design, and construction methods, have changed the overall concept of high-rise buildings and provided a platform to architects for undertaking creative designing of such buildings.
