What is the difference between rigid connection and hinge in steel structure?. Are all high strength bolts connected just now?
In fact, steel joints are generally difficult to be made of pure rigid joint or pure hinge. Likewise, different arrangement of different performance such as rigid hinged pillars generally stiffened column base, anchor bars in the bottom edge is more rigid. If the steel column base section reduced, ribbed or not and anchor bar closer to the section is more biased hinge. Whether the beam has been joined or not, the simpler way is to see if the flange is welded. If welding is partial to the line, if it is not welded, it will hinge on the hinge.
Is to see the node connecting column or beam can rotate around the node, not rotating, that is articulated, can not rotate, that is, consolidation. The simply supported joint is the hinged support, and the rigid joint is the rigid joint of the joint. High strength bolts are not rigid, in the beam web connection, is articulated, ideal for Web Center is a bolt, you can think about it if the middle of the beam stress, beam can rotate around the bolt, but the flange has high strength bolts or welding flange. Do you want to look at the beam can rotate around the node? You understand that, and it's easy to understand when all the bonding is done.
The difference between the rigid connection and the hinge is whether the support passes the bending moment. Rigid transfer moment, hinge not transfer moment. Simply supported is hinged, solid support is rigid. High strength bolts are mainly used for shearing, and whether they are connected directly or not.
