Tall and slender buildings are sensitive to the dynamic effects of wind flow in both service and strength levels
The across-wind load typically governs the design load for tall and slender buildings, this paper focuses on the relationship between yield strength and aerodynamic force in the along-wind direction, which is an important aspect of inelastic design
Summary
Tall and slender buildings are sensitive to the dynamic effects of wind flow (commonly known as resonant load) in both service and strength levels. Buildings were designed under wind load to behave in the elastic range for both service and strength. Based on the criteria and philosophy, inelastic behavior under service load is considered unacceptable. No such criterion exists for strength-level load. To mitigate resonant load through the allowance of plastic deformation, inelastic wind design as part of performance-based wind design (PBWD) has recently received attention. Since tall buildings are typically designed for seismic load in addition to wind load, detailing and reliance on seismic available capacity is an option
