Review and Study of Structural Systems of High Buildings-A Case Study; National Telecom Corporate (NTC) Tower Analysis and Design

Abstract

This thesis deals with the study of structural systems of high-rise buildings and the analysis and design of vertical elements of NTC building in Sudan as a case study. The study comparison and display of some high rise buildings and addressing the general description of them, their structural systems and construction methods, and also discusses the possibilities of high- rise buildings construction in Sudan. Analysis of NTC building in Sudan was performed using the structural analysis and design program (ETABS) and the code UBC97 for earthquakes loads, the British code BS6399 for wind loads, and the British code BS8110-1: 1997 code design. The results were compared with those of the original design. This study concluded that the choice or the optimal structural system depends on the calculate of the horizontal and vertical elements and method of construction, taking into account the advantages and disadvantages of each system and previous experience in structural systems. It also concluded that for NTC building it was possible to use the system that contains columns and deep spandrels around the building and core in the middle for internal planning.
