Rigid Portal Frames
This chapter presents an application of the DAD approach to the design of portal frames, wherein time‐domain methods allow wind effects to be calculated by using large numbers of stored time series of measured pressure coefficients, and wind effect combinations are performed objectively and rigorously via summations of time series. It presents an updated version of this approach and a case study that calculates peak demand‐to‐capacity indexes (DCIs) directly used by the structural engineer to size structural members of gable roof building frames. Aerodynamic databases contain time histories of simultaneously measured pressure coefficients at large numbers of taps. Climatological databases consist of directional or non‐directional extreme wind speeds that account for the building's directional terrain exposure, and cover periods in the order of typically tens of years of measured data or as many as thousands of years of synthetic data.
