This paper presents a simple displacement-based seismic design method for RC frames with steel damper column. As numerical example, two 10-story frame building models are shown. The results of nonlinear time-history analysis show that the peak displacement at equivalent height is close to target displacement. strength demand beam ends connected columns, and beam-damper column joints, calculated...

Serviceability of buildings is affected by excessive acceleration experienced at the top floors in wind storms that may cause discomfort to the occupants. To ensure functional performance of tall buildings it is important to keep the frequency of objectionable motion levels below the discomfort threshold. This paper addresses a new approach that facilitates mitigation of wind induced motion of ...

earlier studies have shown conclusively that a tuned liquid damper (tld) is effective for controlling vibrations in structures subjected to narrow-banded wind excitations. a recent numerical study has shown that if the design parameters of a tld are properly set, this device could also be very effective for controlling structural vibration to broad-banded earthquake excitations. here the result...
