ABSTRACT

 

This paper has provided a broad overview of different historic developments for concrete high-rise buildings.  The evolution of concrete skyscrapers from the first reinforced concrete high-rise, the Ingalls Building, which was 15 stories high to modern skyscrapers Petronas and the Jin Mao is discussed. How new innovations in construction technology such as the advances in formwork, mixing of concrete, techniques for pumping, and types of admixtures to improve quality have all contributed to the ease of working with concrete in high-rise construction is also briefly discussed in the paper.
