This Excel sheet offers a simplified tool for wind load analysis of low-rise buildings per ASCE 7-98. It assists in determining wind pressures on walls and roofs depending on inputs such as building height, wind speed, exposure type, and importance factor.
ASCE 7-98 Wind Load Methodology for Low-Rise Buildings
ASCE 7-98 (Minimum Design Loads for Buildings and Other Structures, 1998 edition) introduced an envelope procedure specifically for low-rise buildings — defined as those with a mean roof height not exceeding 18 m (60 ft) or the least horizontal dimension, whichever is smaller. This simplified method was developed because the general analytical method overestimates wind effects on low-rise structures.
The envelope procedure uses pseudo-pressure coefficients (GCpf) that capture the worst-case combined wind loading from any wind direction, reducing the complexity of directional analysis.
