摘要: The capability of seismic resistance is the most important factor of structures in Taiwan. To improve the function of shock-resistant, the energy dissipators, isolated-resistant and specific structural forms for earthquake resistance are very much in vogue research. In this paper, the experimental methods are used to investigate the property of low yield steel. The component of Carbon for LYS is lower than the other steels; the ultimate stress is three times as large as the yield stress. The ratio of the ultimate elongation is about 62% and the ductility is 2~3 times of the A36 steel. Rhombic steel plate of energy dissipator test using LYS, indicates that the LYS is stable to dissipate or absorb the input energy of the earthquake. It is very useful to apply this device to the plastic hinge, plastic shear link bar and the other energy absorption and dissipators.
對位於地震帶的臺灣而言,結構體之耐震能力,顯得十分重要;為增進結構物對 地震之防災功能,因此制震、減震、隔震等控制,一直是熱門的研究課題之一。本文將以 實驗方法探討低降伏強度鋼板之特性,發現其含碳量低於其他鋼材,機械性質具良好應變 硬化特性,極限應力可達降伏應力之三倍,而極限伸長率約為62﹪,其延展性更為結構用 鋼材(A36)之2~3倍;實際應用於新研發之菱形鋼板,進行消能試驗,發現其確實能發 揮金屬制震器應具有之穩定消能的效果,有利於塑性鉸、塑性剪力連桿或其他消能機制之 控制。
