摘要 本文依規範設計韌性抗彎矩構架，加裝加勁阻尼構架於梁柱構材內，以提高整體系統的勁度及強度做為抵抗地震力的第一道耐震的防線。其設計加勁阻尼構件的原則，為原韌性抗彎矩構架於設計地震力下的各樓層相對位移能控制於所訂的層間變位值。另外控制各樓層加勁阻尼裝置的降伏位移，以確保加勁阻尼裝置於設計地震力下能提供足夠勁度，保護梁柱構材。 依設計程序設計實際設計出低、中、高三種加勁阻尼構架，並且依照不同的樓層相對位移折减率 及 ，設計加勁阻尼構架作為比較。本文亦探討各設計實例於地震下行為的表現。 ABSTRACT A design procedure for steel frames installed with TADAS devices is presented in this study. The aim of the design is to control the story drifts of steel frames to some specific limits. Following the proposed design procedures, six TADAS steel frames with different story numbers and different reduction factors on story drifts were designed according to the seismic design code of Taiwan. For comparison purposes, three bare frames with different story numbers were also designed. Comparative studies of the nine designed structures using inelastic static and dynamic analyses have shown that the seismic behaviors of the moment resisting frames can be amended significantly when the TADAS devices are used. It is also observed that, even the TADAS steel frames were shocked by the near fault earthquakes records, none of beam and column elements yields. The results also confirmed that the proposed design procedures for the TADAS steel frames is validated for mitigating structural damages from strong earthquake shocks.
