in the past of structural bolts in niches industrial and petrochemical complexes, and structures used in the oil and gas industry use it was. But now the application of these structures in residential buildings, office and commercial, that in cities, also can be built from day to day are increasing. In this paper, by screw connections, steel structure, bolts it instrument.
specifications Bolt and nut steel structure
structures, steel structure collection&drop of components, structures, Whoa, that means connections are connected to each other are . Screw used in structures, the steel structure has three major parts, screws etc. bolts, nuts, gaskets, each of which is through standards international identifiable, production, and use. connections if the correct design stocked for Ring weak the link accordingly, safety and service this building will suffer from risky, can formation and ... calculate and plan the details of a connection, if from plan members, the main important building more is not, at least in the same degree of importance are located. Each metal structure the combination of members apart, can that is, these members have to go through a decent to each other are connected.
performance connecting reinsurance
in action steel structure bolts O reject the reinsurance., the screw inside the hole pages, connect the place a bead pack can be. When the that the load external to the enter be., the parts connection, slip can find that in effect it, a compressive force to the edge of the connection enter that convert to a shearing force in the screw, can crafted. This connection is only for mode share ثقلی can is in plan seismic not this kind of performance in the connection used. In this connection, no force, the prestressing in the screw, do not create and for the implementation of this connection. only tighten the screws to the means the worker adequacy, can does.
performance connector frictional
when the that screw into the hole in the junction plates are placed in. Additionally the nut should be of the gasket is also used. It should be noted that the gasket used in the connection, the friction should not be of the type, washer, bouncy is. Based on the topic tenth in the design of seismic only have the performance of the design in the connection used. In other words, in the design of all the connections frame, the flexural and frame dual and also fitting بادبندی and patching the column Barber side frame simple have this kind of performance used. In this type of connection, in addition to tightening the first bolt, you have to make some that design, specify is the force of prestressing is also in the Bolt created.
