Crack Damage Distribution of Concrete Filled Steel Tube Frame under Extremely Strong Ground Motion
Abstract eng: Seismic response and crack damage of concrete filled steel tube frame (CFT-frame) under strong ground motion are numerically analyzed and the damage ratio and damage distribution in the frame are investigated. In order to prevent the damage concentration, the design condition of CFT-frame expressed by the strength ratio of concrete to steel tube is derived from the numerical results of seismic response and damage ratio distribution. CFT-frames are designed on the basis of the proposed design condition and the calculations of the seismic response and damage of them have been carried out. From the calculated results, it is ascertained that the proposed design condition of CFT-frame is useful to prevent the damage concentration in CFT-frame under strong ground motion.
