Abstract
Structural systems for tall buildings have evolved to produce higher lateral stiffness more efficiently. This study investigates comparative structural efficiency between today's prevalent structural systems for tall buildings, based on lateral stiffness. Tall buildings of 40, 60, 80 and 100 storeys are optimally designed with braced tubes, diagrids and outrigger structures to meet the lateral stiffness requirements. The structural efficiency of each system is studied comparatively depending on building heights and height-to-width aspect ratios. More efficient system selection and design optimisation can substantially contribute to constructing sustainable built environments by saving building materials produced from our limited resources.
期刊介绍：
The International Journal of Sustainable Building Technology and Urban Development is the official publication of the Sustainable Building Research Center and serves as a resource to professionals and academics within the architecture and sustainability community. The International Journal of Sustainable Building Technology and Urban Development aims to support its academic community by disseminating studies on sustainable building technology, focusing on issues related to sustainable approaches in the construction industry to reduce waste and mass consumption, integration of advanced architectural technologies and environmentalism, sustainable building maintenance, life cycle cost (LCC), social issues, education and public policies relating to urban development and architecture .
