Modeling of wind loads on low-rise buildings is complicated by their variety of geometries and surroundings and remains a very challenging issue which is critical for cost-effective design and reduction of wind-induced losses. Current design practice often requires the transformation of spatiotemporally varying wind loads to the equivalent static wind loads (ESWLs). This paper addresses the analysis of wind load effects and modeling of ESWLs on low-rise buildings based on the full scale dynamic pressure data of the Wind Engineering Research Field Laboratory (WERFL) building at Texas Tech University. The ESWLs for different peak wind load effects of building frames under both alongwind and acrosswind excitations are examined using a number of approaches with a focus placed on developing physically meaningful and convenient wind load models for potential design applications. The results of this study demonstrated the advantage of the gust loading envelope approach for improved modeling of wind loads on low-rise buildings. Copyright ASCE 2006.
