Abstract
A beam-to-column connection is suitable for connecting an H-beam to a column surface. The connection is defined at an end of the H-beam which has a web plate and a pair of flange plates. The connection comprises a web plate member integrally formed with the web plate of the H-beam; and a pair of flange plate members, each of which is integrally formed with the flange plates and has a tapered zone.
Claims8
An apparatus for connecting an H-beam, to a column surface, said apparatus comprising:
- the H-beam having a pair of flange plates and a web plate positioned between the flange plates, a plastic moment capacity and a demand moment capacity;
- a web plate member disposed at an end of the H-beam integrally formed with said web plate of said H-beam;
- and
- a pair of flange plate members also disposed at an end of the H-beam respectively integrally formed with said flange plates, each of the flange plate members including means for reducing the plastic moment capacity of said H-beam to an amount of 90%.about.95% of the demand moment capacity of said H-beam, said reducing means comprising a tapered zone that is non-uniform.
An H-beam comprising a web plate connected to a pair of flange plates, each of the flange plates having a width, the H-beam having a plastic moment capacity, a demand moment capacity and, at an end of the H-beam, a region having a tapered zone of non-uniform width in the flange plates to reduce the plastic moment capacity of the H-beam to about 90 to 95% of the demand moment capacity of the H-beam.
An H-beam having a plastic moment capacity and a demand moment capacity and a tapered zone at an end of the H-beam which is adapted to form a connection to a surface, wherein the tapered zone is non-uniform to provide the plastic moment capacity of the H-beam which is about 90 to 95% of the demand moment capacity of the H-beam.
