Design of high-rise buildings with arbitrary shapes for multi-directional wind

Abstract

This communication presents a high-fidelity procedure for the design for wind of high-rise buildings with any shape, and briefly comments on procedures used in current wind engineering practice. Main features of the high-fidelity procedure include: the development of accurate relationships between wind velocities and peak wind effects (demand-to-capacity indexes, inter-story drift ratios, accelerations), which allows the creation of extreme wind effect data samples; the use of those samples for the statistical estimation of N-year peak wind effects consistent with performance-based design requirements; full transparency, enabling thorough scrutiny of the procedure; and an effective integration of wind and structural engineering tasks that effectively streamlines the design iteration process.
