Title: Ultimate Capacities of Low-Rise Steel Frames in Turbulent Wind
Published: July 01, 2001
Abstract: This paper is a derivative of G2001-1392, Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames, by Jang, S., et al., intended for publication in the Journal of Structural Engineering.The original paper's abstract was:A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns (magnitude and distribution) established from aerodynamic databases on the one hand, and on patterns specified in the ASCE 7 Standard on the other. The estimated capacities are based on the assumption, verified by numerous sets of calculations, and also used in the development of the ASCE 7 Standard, that the most unfavorable wind load occurs at the instant in time when the peak knee-joint bending moment is attained. The estimates are obtained from detailed inelastic finite-element analyses of the frames with ultimate states associated with local and global instabilities. It is shown that the estimates based on the aerodynamic database are more realistic and risk-consistent and can therefore lead to safer designs at lower costs. These estimates represent a significant advance over the ASCE 7 Standard-based estimates.
