Strength bolt connection
High strength bolt connection of steel structure is a new form of connection, it has the advantages of simple construction, good mechanical performance, removable, fatigue and under dynamic loads without loosening and other advantages, is a promising method of connection. It is widely used in modern steel structure building.
Rivet connection
