Many steel structures have been constructed with high-strength steels and ultra-thick steel plates in accordance with the development of steel materials. Steel structures such as steel bridges have to be connected with bolts or welding. The bolted joints are more frequently used in the field due to easy management. Domestic KS(Korea Standards) reads that bolted connection must be at least 75% of strength of member; however, it seems to be very conservative. This study aims to examine appropriateness of the conservative KS(Korea Standards) by analyzing formation of bridge under construction. Furthermore, more economic and efficient way without degrading any strength of bolted connections was suggested here.
