Wind and Structural Engineering: Ensuring an Effective and Transparent Division of Responsibilities



Emil Simiu, Dong Hun Yeo


To help assure safe performance under loads that may occur during a structure s life, structural design practices are regulated by code provisions, and the design of the structure must be approved by a qualified public official. For the design and approval process to be effective, the design procedure must be (1) clear, (2) transparent, (3) sound, and (4) sufficiently well documented to allow careful scrutiny, as well as comparisons with results obtained by alternative engineering laboratories. Recent evidence suggests that achieving this goal on tall building projects, which entail strong interactions between wind and structural engineers during the design stage, requires improvements in wind and structural engineering practices. The first part of this paper attempts to show why, in our opinion, such improvements are necessary. The second part of the paper describes a procedure for the design of tall structures subjected to wind loads that satisfies the four requirements listed above, while clearly delineating the distinct responsibilities of the wind engineer on the one hand and of the structural engineer on the other.
