Design of High Rise Reinforced Concrete Buildings

Abstract

Design of a high-rise reinforced concrete building, like any engineering design, is a complex multidisciplinary process with the objective to discover, detail and construct a system to fulfill a given set of performance requirements. The success of this process is highly dependent upon the cooperation taking place between the members of the design team. Although present-day engineering computer technology allows for precise analysis and design of the different subsystems of the high-rise building, it does not readily provide insight for choosing among alternatives of these subsystems to arrive at the best overall design. The thesis begins with a review of the design of high rise buildings and the conceptual design of it. Then the study is carried out to investigate some special structural problems. The configuration examined in this study was a square twenty eight (28) story reinforced concrete structure, for three (3) different structures: the first one is core wall structure without bracing, the second is core wall structure with bracing system and the third is shear wall structural system. These three different structures subjected to different load combinations, the final result is analyzed. The analysis of the structural form performed using ETABS software program by two methods of analyzing, equivalent static method (static analysis) & response spectrum method (dynamic analysis) and the results of the analysis compared such as, displacement, drift, shear force and moment between the three structures in each methods. The design results presented in tabular form.
