| Description |
Open latticed steel towers are used widely in a variety of civil engineering applications. Along the east coast
of India, many latticed towers, located in cyclone prone zones, have collapsed during cyclones with lesser wind
speeds than the design basic wind speed. Dynamic effects of wind for design of lattice towers are simplified by
most of international codes of practice with the use of Gust Effectiveness Factor (GEF). The application of gust
effectiveness factor have been evaluated as per various international codes of practice and are compared in this
paper. Case studies of failure analysis to identify the causes of possible failure of two microwave latticed towers,
which collapsed in cyclonic wind conditions, are presented. Characteristics of a measured cyclone wind turbu-
lence spectrum are used along with a practiced gust effectiveness factor approach or equivalent for the dynamic
analysis
