Abstract
This paper is primarily concerned with the design of various structures for wind forces from the viewpoint of the average structural engineer. The subject matter focuses attention on three important types of structural problems whose solutions are still so uncertain as to require considerably more study and research. The problems are: wind action upon structural frameworks during construction, with emphasis on the relatively large number of partial or complete failures, and the behavior of completed structures of relatively high frequencies when subjected to wind loads. Important factors here are the amount and characteristics of motion in high-rise buildings that will be accepted by the occupants, and some dynamic problems associated with wind forces acting upon structures of low frequencies such as tall chimneys and guyed towers. The above problems are discussed from the need for better design criteria and specifications, as well as more exact mathematical analysis and more refined wind measurements. The importance of the latter factor is recognized, but the many empirical factors in structural design also are considered in this paper.
