摘 要
近年來高層鋼骨建築在國內日益普遍,有鑑於美國洛杉磯北嶺地震(1994)與日本版神地震(1995)的嚴重災難,鋼骨結構的耐震能力也因此受到國人的重視。在北嶺地震中抗彎構架接頭焊接與設計的不良反應,同樣存在於偏心斜撐(EBF)連桿梁接柱接頭中。在北嶺地震後,世界各國已有許多實驗針對抗彎構架的接頭進行研究。然而,對於受力與變形需求較高的EBF連桿梁接柱接頭所做的探討仍極為有限;本研究就偏心斜撐構架連桿梁接H型鋼柱接頭進行試驗,以中等長度之連桿作為探討對象,分為五組試體兩種設計長度,分別為e=1.4m M1系列試體三組與e=1.6m M2系列試體兩組。連桿梁腹板與柱接合之細節亦分為兩種方式:(1)以螺栓接合剪力板與連桿梁腹板與(2)以全滲透焊接合梁腹板與柱面。藉由這五組試體來比較分析中等長度之連桿梁,因長度、腹板接合方式及翼板加勁、切削之差別,在模擬地震力之反覆載重作用下,其梁柱接頭之行為及破壞模式,以供後人設計之參考。因為試驗時程延遲,本文只呈現其中一支試驗試體試驗成果。
ABSTRACT
In recent years tall steel buildings have been increased day by day in Taiwan.Owing to serious calamities resulted from Northridge earthquake and Kobe earthquake,seismic resistance of the steel frames have got more attention recently in Taiwan.
Many of the design and welding conditions responsible for the poor performance of moment frame connections in the Northridge earthquake are also presented in the link to column connections in the Eccentrically Braced Frames(EBFs). A large number of experimental investigations on the performance of weld moment connections have been conducted in the US after the Northridge earthquake. However, the experimental data on the performance of link-to-column connections in EBFs are seldom found.
This research aims at investigating the cyclic performance of middle length link-to-H column connections. There are five specimens divided into two different link length categories. Three specimens are designed with the link length of =1.4m (M1-Series),and the other two of =1.6m(M2-Series). Two different link beam web-to-H column connections details are tested.One is connecting the beam web to the shear tab by bolts. the other is connecting the beam web to the column by groove welds.
Based on the test performance of five specimens, difference in the behaviors and failure patterns of middle length links beam-to-H column connections under cyclic load, resulted from different link length﹐beam web to column connections and beam flange to column connection such as flange cover plates and Reduced Beam Sections (RBS) may be distinguished﹐for the reference of future design.
However﹐test results of only one specimen are displayed in this research due to the delay of the tests.
