Abstract
As the application of post-frame buildings has increased, rigorous design methods have been developed to accurately model how these buildings perform under lateral loading. Such methods attempt to predict the force distribution interaction between the post-frames and roof diaphragm. This is a complex analysis that requires computer software that may not be necessary when designing all post-frame buildings. This paper describes a rational, simplified procedure for lateral design of post-frame buildings that conservatively ignores the contribution of frames to the lateral building stiffness, does not require costly computer software, and allows the designer to predict deflection, roof/wall shears, and maximum post bending moments. This simplified method was compared to what is considered the state of the art post-frame design methodology. Building wall heights of 12 and 16 ft, widths of 40 and 56 ft, and effective diaphragm shear moduli of 4.7 and 7.5 k/in. were examined for building aspect ratios ranging from 1:1 to 4:1. The simplified method gave conservative design values for unit shear, eave deflection, and maximum post moment compared to the more complicated procedure that accounts for frame-diaphragm interaction, and proved it can be conservatively substituted for a simplified design of post-frame buildings.
