The Commonality of Earthquake and Wind Analysis
Earthquakes and wind loadings constitute dynamic effects that often must be considered in the design of buildings and structures. The primary purpose of this research
study was to investigate the common features of general dynamic analysis procedures
employed for evaluating the effects of wind and earthquake excitation. Another major
goal was to investigate and develop a basis for generating response spectra for wind
loading, which in turn would permit the use of modal analysis techniques for wind
analysis in a manner similar to that employed for earthquake engineering. In order to
generate wind response spectra, the wind loading is divided into two parts, a mean
load treated as a static component and a fluctuating load treated as a dynamic component.
The spectral representation of the wind loading constitutes a simple procedure
for estimating the forces associated with the dynamic component of the gusting wind.
Several illustrative examples are presented demonstrating the commonality.National Science Foundation Grants ENV 75-08456 and ENV 77-0719
