Abstract

This paper describes an integrated topology optimization framework using discrete and continuum elements for buckling and stiffness optimization of high-rise buildings. The discrete (beam/truss) elements are optimized based on their cross-sectional areas, whereas the continuum (polygonal) elements are concurrently optimized using the commonly known density method. Emphasis is placed on linearized buckling and stability as objectives. Several practical examples are given to establish benchmarks and illustrate the proposed methodology for high-rise building design.
