Description

This manual, Wind Tunnel Studies of Buildings and Structures (ASCE Manuals and Reports on Engineering Practice No. 67), is a revision of the first edition published in 1987, and provides guidelines intended to assist architects and engineers who may become involved with wind tunnel model testing of buildings and structures. Wind tunnel testing is desirable in order to improve the reliability of structural performance and to achieve cost effectiveness—both of the final structure and during the period of construction. This revised edition includes procedures required to provide representative information on wind effects experienced during certain wind conditions and methods for using such information to provide statistical predictions of full-scale behavior. New developments are presented in the wind engineering field and wind tunnel studies of the dispersion of pollutants around buildings and in urban environments.
