摘要(中) 抗彎框架具有顯著的延展性從而在抗震設計是常用的。然而,由於較低的剛度和結構強度過度變形限制了系統的適用性。提高了系統的結構性能,一個鋼彎曲阻尼器,提出了這項研究。彎曲的阻尼器設計成能放置在梁到塔的區域。風門行為是由它的兩端之間的長度和角度的約束。為了更好地理解上的結構性能的增強彎曲阻尼器的效果,一系列循環載荷試驗進行的。結果發現從試驗結果可知,阻尼器強度較高時風門的角度較小。也有人從結果的比較觀察到,在強度,剛度和能量耗散顯著改進時所提出的彎曲阻尼器加入到該抗彎幀得以實現。最後,彎曲阻尼器的有效的設計建議,提出了工程實踐。
摘要(英) Moment resisting frames possess significant ductility thus are commonly used in the earthquake-resistant design. However, excessive deformation due to lower stiffness and strength of the structures limits the applicability of the system. To improve the structural performance of the system, a steel curved damper is proposed in this study. The curved damper is designed to be placed at the beam to column regions. The damper behavior is governed by its length and angle between the two ends. To better understand the effect of curved dampers on the enhancement of structural performance, a series of cyclic loading test were conducted. It was found from the test results that the damper strength was higher when the angle of damper was smaller. It was also observed from result comparisons that significant improvements in strength, stiffness and energy dissipation were achieved when the proposed curved dampers were added to the moment resisting frames. Finally, effective design recommendation of curved dampers is proposed for engineering practice.
