Evaluation of effect of tuned liquid dampers and modified tuned liquid dampers on seismic response of steel moment resisting frames

Severe damages of structures during large earthquakes and the loss of national wealth has made it extremely important to reduce the vibrations of structures against wind and earthquake. One of the efficient ways to reduce these vibrations, is to use the tuned liquid damper (TLD). The tuned liquid da...
