Sustainable structural engineering strategies for tall buildings

Sustainable structural engineering strategies for tall buildings are presented with an emphasis on stiffness-based material-saving design methodologies. The design methodologies are applied to the systems with diagonals such as braced tubes and more recently developed diagrid structures. Guidelines for determination of bending and shear deformations for optimal design, which uses the least amount of structural material to meet the stiffness requirements, are presented. The impact of different geometric configurations of the structural members on the material-saving economic design is also discussed, and recommendations for optimal geometries are made. The design strategies discussed here will contribute to constructing built environments using the minimum amount of resources. Copyright © 2008 John Wiley & Sons, Ltd.
