【摘要】：焊接作為超高層鋼結(jié)構(gòu)建筑的主要連接形式,焊縫形式和等級(jí)正確與否對(duì)整個(gè)建筑的安全至關(guān)重要。節(jié)點(diǎn)區(qū)是各種焊縫的交匯區(qū),根據(jù)世界震害實(shí)錄分析表明,許多鋼結(jié)構(gòu)都是由于節(jié)點(diǎn)焊縫首先破壞而導(dǎo)致建筑物整體破壞的,因此對(duì)節(jié)點(diǎn)區(qū)焊縫形式和等級(jí)的選用需審慎。通過(guò)對(duì)各節(jié)點(diǎn)的受力情況進(jìn)行分析,來(lái)確定各部位的焊縫形式;同時(shí)結(jié)合《鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范》GB50017—2003第7章關(guān)于焊縫等級(jí)的選用,來(lái)確定各處的焊縫等級(jí)。
[Abstract]:Welding is the main connection form of super high-rise steel structure building. Whether the weld form and grade is correct or not is very important to the safety of the whole building. The joint zone is the intersection zone of all kinds of welds. According to the analysis of the earthquake damage in the world, it is shown that many steel structures are destroyed as a whole because of the first destruction of the joint welds, so the selection of weld forms and grades in the joint zone should be careful. Through the analysis of the force of each joint, the weld form of each part is determined, and the weld grade is determined according to the selection of weld grade in Chapter 7 of GB50017-2003.
