A STUDY ON EFFECT OF APPLYING LARGE DIAMETER BOLTS ON FABRICATION COST

概要

論文の詳細を見る
High strength bolted connections have been designed for four types of steel bridge using F10T class bolts with 22, 30 or 36mm in diameter (M22, M30 or Ml6), the number of bolts (the number of holes) and the weight of splice plates have been calculated, and then the material cost (bolts and splice plates) have been estimated. Working time for opening the holes and tightening the bolts have been also estimated for the designed connections. On the basis of these results, the influences of bolt diameter used on the material cost and working time have been indicated for each type of bridge.
