Wind Analysis for Trussed Tower Based on ASCE 7-16
Wind analysis for trussed tower sheet examines structural forces present in a four-sided truss tower modeled as a
support system for a wind turbine. Case l examined only forces due to the weight of the nacelle and rotor, while Case ll
also incorporated lateral wind force. All forces were idealized as concentrated forces and theoretic analysis was
completed using static equilibrium concepts and truss/frame analysis techniques A PASCO Structure kit was used to
construct a model and validate theoretical findings. Weights were applied to the model and the resulting axial forces
were measured using load cells. Experimental data concurred with the theoretical analysis within the measured
uncertainty, indicating the tower was accurately analyzed as a frame/truss structure.
