Performance-Based Wind Design of Tall Buildings Considering the Nonlinearity in Building Response

Advancement in performance-based wind design :

“…However, most work to date has primarily focused on establishing the feasibility of carrying out nonlinear wind analysis and is based on direct integration approaches developed in seismic engineering. While recent advancements have occurred in this area-for example, the suite of methods that combine direct stochastic simulation with dynamic shakedown (Chuang and Spence 2019, the approaches based on reduced order models (Wu 2013;Wu and Kareem 2015;Zhao et al 2019;Li et al 2021;Li and Spence 2022a,b,c), and the methods that leverage machine learning (Li and Spence 2022a;Preetha Hareendran et al 2022)-much work remains to solve the problem of rapidly evaluating the nonlinear response of wind-excited structural systems in ways that are both robust to the complexity of the computational models that describe the nonlinear response of systems and compatible with general purpose uncertainty propagation schemes. Areas with promises in this respect are those related to metamodeling/surrogate modeling, reduced-order modeling, methods for leveraging massive parallelization through GPUs and supercomputing, and methods that leverage artificial intelligence (e.g., physics-informed and/or data-driven machine learning).…”

“…Most SPO applications have focused on analysis of transmission towers and offshore turbines (Bienen and Cassidy 2006;Banik et al 2010). With the increasing attention on PBWD, research on performance assessment for structures under wind loads has been developed and SPO has usually served as one of the assessment steps for tall buildings (Mohammadi et al 2019;Ghaffary and Moustafa 2021;Preetha Hareendran et al 2022). Huang and Chen (2023) applied modal pushover to wind analysis for a 60-story high-rise steel building.…”

“…In wind engineering, Ghaffary and Moustafa (2021) developed the SPO to wind analysis for a 20-story steel building with the loading distribution proportional to a value associated with story height, mass, and the building's natural frequency (Group 1, Method 1), which is the most widely used method in seismic analysis. However, most of the wind SPO developed for tall buildings directly use and scale the equivalent static wind load from the ASCE/SEI 7 (ASCE 2022) directional procedure based on Davenport's gust loading theory (Davenport 1967;Mohammadi et al 2019;Preetha Hareendran et al 2022). The purpose of developing the equivalent static wind load is to use the static method to predict the maximum dynamic response.…”
