Abstract
Predicted dynamic characteristics of one 15 feet high and two 30 feet high lattice mast structures are presented and compared with experimental data. Large general purpose finite element computer programs were used to calculate mode shapes, natural frequencies and transient responses under air blast loading. Methods used to determine the loading functions for transient response analysis are described.
