Abstract

In recent years, wind design, particularly for high-rise buildings, has seen a paradigm shift from a code-based descriptive method to a more specific performance-objective-based design. This new approach, known as the Performance-Based Wind Design (PBWD), aligns with community needs and goals. Achieving an economical and safe level of performance-based design necessitates a more rigorous data-driven analysis, as outlined in the PBWD Prestandard. NIST has developed a Database-Assisted-Design (DAD) method for tall buildings that reliably estimates peak combined wind effects and wind directionality at a building site by utilizing time-domain analysis and local climate data. The most recent improvement of the DAD method, a product from collaboration between NIST and industry partners, involves the integration of a Python-based platform and the use of ETABS. This development improves the practicality of DAD in design practice. Preliminary comparison results with the code-based method demonstrate the effectiveness of the DAD method and its significant potential for PBWD.
