This study quantitatively clarified how slip deflections of shear bolted joints contributed to damping characteristics by static loading tests, free vibration tests, and non-linear numerical response analyses of trussed towers. It was proved that static load-deflection characteristics of towers could be calculated by sum of characteristics of elements such as members and bolted joints. It was clarified that each maximum damping ratio of two full scall towers at first natural free vibration tests was greater than 4 %. And damping ratios were estimated from static load-deflection characteristics. Accuracy of dynamic response analytical method incorporated with bolted joints converted to non-linear spring elements having simplified slip characteristics was proved by comparing with free vibration tests. Non-linear responses used damping ratios varied according to amplitudes were compared with linear seismic responses used fixed equivalent damping ratios. Therefore it was clarified that the equivalent damping ratios were equal to about half of damping ratios in first natural free vibration.
