17日发生的神户地震。1995年,在神户市地区造成大量建筑物广泛而严重的破坏。地震后,许多钢结构采用焊接结构与焊接底座的框架焊接连接方式建造。然而,这些焊缝在地震中吸收能量的能力很小。因此,认为在采用焊接接头的钢结构设计中,必须特别对钢焊接基础的接头提供较强的抗震性能。此外,这些焊缝在地震中吸收能量的能力很小。因此,在设计采用焊接接头的钢结构时,必须特别对焊接底座的接头规定较强的抗震性能。此外,结构监测将是必要的。本文通过简单的动态测量和仿真,利用压电接头传感器对角焊缝结构的阻力和位移特性进行了评估。
The Hyogoken Nanbu earthquake (Kobe earthquake) that occurred on January 17. 1995, caused extensive and severe damages to a large number of buildings in Kobe city area. After the earthquake many steel structures were constructed using frame welded joint of welded construction and welded base. However, the capacity of these weld joints to absorb energy during earthquakes is small. For that reason, it is believed that in the design of steel structures that use welded joints, strong earthquake resistant characteristics must be provided in special for those joints of the steel welded bases. Moreover, these weld joints have little capacity to absorb energy during earthquakes. Therefore, for designing steel structures incorporating welded joints, strong earthquake-resistance characteristics must be specially provided for those joints of steel welded bases. Furthermore, structural monitoring will be necessary. Using simple dynamic measurements and simulations, this report evaluates the resistance and displacement characteristics of fillet welded construction by piezoelectric joint sensors.
