Abstract
Strength reduction was investigated when a double-skinned composite tubular (DSCT) member was exposed to welding heat. And a method for a DSCT member to maintain its original strength against the welding heat when modular DSCT members are composed. Welding causes the heat of 20,000°C on the weld zone and the heat of 1,300°C around the weld zone. The strength of concrete nearby the weld zone decreases by high temperature. In this study, the concrete strength cases were investigated when arc welding and electro slag welding were used as the welding methods. Through heat transferring analysis of welded DSCT members, a preventing method preventing concrete strength reduction was proposed. The proposed method showed it prevented concrete strength reduction and it was verified by finite element analysis (FEA).

N2 - Strength reduction was investigated when a double-skinned composite tubular (DSCT) member was exposed to welding heat. And a method for a DSCT member to maintain its original strength against the welding heat when modular DSCT members are composed. Welding causes the heat of 20,000°C on the weld zone and the heat of 1,300°C around the weld zone. The strength of concrete nearby the weld zone decreases by high temperature. In this study, the concrete strength cases were investigated when arc welding and electro slag welding were used as the welding methods. Through heat transferring analysis of welded DSCT members, a preventing method preventing concrete strength reduction was proposed. The proposed method showed it prevented concrete strength reduction and it was verified by finite element analysis (FEA).
