钢框架结构的震害及其原因
|
摘要
在美国的北岭地震和日本的阪神地震中,钢框架结构发生的震害引起了各国学者注意。震害主要发生在梁柱焊接节点处。在阪神地震中还发生了钢柱的脆断和柱脚的破坏。结合各国学者的研究,对北岭和阪神地震震害进行比较,分析震害发生的原因。
The damage to steel frame buildings in the Northridge Earthquake and Kobe Earthquake has arisen out of the interest of scientists.The main damage observed after the earthquakes was the fracturing of beam-to-column connections of steel frames.The brittle fracture of steel columns and the damage to column bases were found in Kobe Earthquake.With the reseasched results of many scientists,the damage among the beam to colwmn connections and the column bases and the brittle fracture of the steel frames in Northridge Earthquake and Kobe Earthquake is compared,and the causes of the damage are analyzed.
