ABSTRACT
Advances in construction technology, materials, structural systems and analytical tools for analysis and design have facilitated the growth of high-rise buildings. The structural design of high-rise buildings is governed by lateral loads resulting from wind or earthquake. Lateral load resistance is provided by interior or exterior structural systems. Shear wall core and outrigger and belt truss are examples of interior structural systems, while tubular frame and diagrid are examples of exterior structural systems. Sometimes, the combined characteristics of two or more structural systems can be effectively used to satisfy the design criteria of high-rise buildings. This paper explores the shear lag effect in a hybrid structural system for a high-rise building: a G+60-story building with combined outrigger and diagrid structural systems is considered. Modeling and analysis of the building are carried out using ETABS software to evaluate the shear lag effect and compute the shear lag ratio for this hybrid high-rise structural system.
