| Abstract | Dynamic response of two free-standing steel towers subjected to real and pseudo wind records are studied. Pseudo wind records are generated with time-varying mean velocities. Dynamic effects of higher modes and viscous damping are included in the analysis. The maximum deflections obtained from real wind records, pseudo wind records, and the actual dynamic response are compared. It was found that taking two modes in dynamic analysis will give reasonable accuracy in the displacement prediction. Available methods for determining the natural frequencies and modes of the multi degree system are reviewed, and a method of reducing the number of lumped masses is developed. This method modifies both the
mass values and interval of lumping of a system, and yields good accuracy to the fundamental mode. |
