Uncertainties in codal recommendations for across-wind load analysis of R/C chimneys

This paper reviews the prevailing international codal procedures to evaluate the across-wind response of R/C chimneys. The disparities in the codal estimates of across-wind moments as well as the load factor specifications are examined from a reliability viewpoint. Conditions are also identified wherein the across-wind response, rather than the along-wind response, governs the design.
