[提要] 通過(guò)介紹與分析美、日兩國(guó)在諾斯里奇和阪神地震后研究的鋼框架梁柱節(jié)點(diǎn)連接方式與施工方法，
總結(jié)出兩國(guó)梁柱節(jié)點(diǎn)的改進(jìn)措施雖不同，但其目的都是為了避免地震時(shí)梁翼緣與柱翼緣焊接部位的開(kāi)裂，并提出了選擇梁柱節(jié)點(diǎn)連接方式的設(shè)計(jì)建議，供參考。
[關(guān)鍵詞] 鋼框架 梁柱節(jié)點(diǎn) 抗震性能 設(shè)計(jì)建議
The retrofit research work on the design and construction of the steel frame beam-to-column connection, which were practiced respectively in U.S.and Japan after the Northridge earthquake and the Hyogoken-Nanbu earthquake,is introduced and analyzed. Although the improvement measures of two countries are different, their goals are to aviod the welding spot crack on the joint between the beam flanges and the column flanges under the seismic load. Some reason-
able advices are presented for design reference.
Keywords: steel frame; beam-column joints; seismic resistance; design suggestion參 考 文 獻(xiàn)
