Abstract/Description: Truss towers form a vital part of the communication infrastructure, and the control of responses for such structures during adverse events such as an earthquake is of significant importance. The objective of this research venture is to combine the linear quadratic regulator (LQR) algorithm for optimal design of supplemental dampers of buildings with the bi-model method for a truss tower. Damping coefficients are calculated for the 3D truss model by analyzing the dynamically equivalent 2D lumped mass model which is developed using the bi-model method. The dynamic responses of the structure for given seismic loads are computed for the conditions with and without dampers. The results are then compared to determine the efficiency of the method to design passive fluid viscous dampers (PFVD) to control the excess vibrations due to seismic loads in towers.
