| dc.description.abstract | 本研究中提出一種新型阻尼器，並將其命名為「切縫鋼管挫屈束制阻尼器」。此阻尼器同時結合了鋼管與挫屈束制斜撐的特性，在結構物受側向力時，有效展現良好的消能能力。在此消能器中，以最外層鋼管提供束制作用，並利用填充之混凝土控制內層切縫鋼管之後挫屈行為。內層鋼管的切縫設計，可提供不同的結構消能能力，此切縫鋼管的塑性行為可對整體結構提供穩定的消能表現。
研究中針對一系列切縫鋼管挫屈束制阻尼器及配置此阻尼器之半剛接構架進行反覆載重試驗。試驗結果發現，若在阻尼器內層鋼管內做適當的切縫，斜撐構架可在位移比2.5%內展現良好的強度表現和消能能力。由試驗結果比較中得知，加裝切縫鋼管挫屈束制阻尼器的斜撐構架，能有效地提升整體構架在強度、勁度、變形及能量消散上的能力，因此，此阻尼器應為有效之結構耐震性能提升設計。 | zh_TW |
| dc.description.abstract | A new energy dissipation device that combined the BRB and pipe damper systems to form the buckling restrained slit pipe dampers (BRSPD) is proposed. This device incorporates a slit pipe damper that is limited by the inner tube. The outer tube was used as a restraining mechanism. Slit in the pipe is used to control energy dissipation and deformation capacity. This damper is designed to provide adequate hysteretic performance through core yielding under both tension and compression.
A series of cyclic loading tests were conducted on the BRSPD and semi-rigid frames with the proposed devices. It was found that the BRSPD sustained significant strength and energy dissipation capability before reaching 2.5% drift ratio, if adequate number of slits in the core pipe was used. Comparisons of the test results showed that the frame strength was increased when the buckling restrained slit pipe dampers were adopted. Significant gains in strength, stiffness, deformation capacity and energy dissipation for framed structures with BRSPD justified the effectiveness of the proposed design. | en_US |
