The use of high grade steel and concrete in high-rise buildings has increased significantly in the past 20 years mainly owing to improvement in all the materials, technologies and associated methods related to prepare, supply and pour the concrete. Cementations materials, admixtures, aggregates, pumping techniques, transportations and elevation methods…etc. all these enchased possibilities are illustrated by taking 150 story high rise structural model; analyzed and designed by using the software ETABS-2013, to withstand the gravity loads and also the lateral loads considering Wind 100 mph, Exposure-Seismic Zone-I, soil profile type SD, Occupancy category 1.0 and Ductility factor, R=5.5. The type of ultra-high strength concrete cylindrical strength has been considered as 107 MPa @ 28 days to bear the high load and straining action at lower portion of the core wall, Steel sections and plates are confirming to ASTM-A992-Gr:70 Ksi are considered for Built-up column sections and floor beams. In addition Shear Studs conforming to ASTM-A106-Gr:1020 with composite metal deck have also been considered to be have as rigid diaphragm to act as monolithic unit against the heavy lateral loads. This paper clearly would show that the Design and constructability considerations, serviceability requirements and international codes compliances such as ACI-318, ASCE-7, IBC-2011, UBC-1997, further it would prove that the combination of R.C. concrete and steel composite sections could be the best solution for such tall skyscrapers to meet the client interest and expectations.
