Jan 08,1993·Bolted connection is more frequently used than other connection methods.They are very easy to operate and no special equipment is required.This is in particular due to the development of higher strength bolts,the easy to use and strong structural steel connections become possible.In the bolt design,two kinds of forces including tension and shear forces should be considered. results for this questionHow are bolts used in steel?How are bolts used in steel?Bolts are most commonly used in structural steel connections where the line of action of the load is perpendicular to the bolt axis as shown.In this condition the principal force in the bolt is shear.Sometimes the bolts are placed such that their axes are parallel to the line of action of the load.Bolted Connection Principles,Assembly and Strength Civil results for this questionWhat are the Bolts in a butt splice joint?What are the Bolts in a butt splice joint?The bolts in a butt splice joint with two cover plates are in double shear with two shear planes.Shear capacity of each bolt is twice that of the same diameter in a lap joint.Fig.4.7 shows the bolt connection for a hanger.A hanger is shown connected to the bottom flange of a girder.In this connection the bolts are in tension.Bolted Connection Principles,Assembly and Strength Civil

BOLTED TANK DESIGN REVIEW - Tank Connection

As shown,the bolt holes and joint connections are the high stress (in red) problem areas,which is why glass coatings can fracture in the bolt connection area.The steel panel under stress yields in a ductile manner,whereas brittle glass coatings do not.The reinforced tank design utilizes external bands stiffeners to lower stress failure.Bolted Connection Principles,Assembly and Strength Assembly of Bolted Connection All parts of bolted members shall be pinned or bolted and rigidly held together during assembly.The component parts shall be assembled and aligned in such a manner that they are neither twisted nor otherwise damaged and shall be so prepared that the specified camber,if any is provided.Holes in Assembly:CONNECTIONS IN TIMBER STRUCTURES - FITConnections Page 1 of 17 30/01/2006 CONNECTIONS IN TIMBER STRUCTURES 6.1 Introduction The competitiveness of a timber structure,relative to other building materials,may be determined by the efficiency of the connections.In most cases the fastening of timber to timber requires little skill or knowledge of design.
