| 摘要 |
The present invention relates to a hybrid beam which has an end part, which is reinforced with reinforced concrete, which adheres to the reinforced concrete or a reinforced concrete column and, more specifically, to a prestressed end-reinforced hybrid beam capable of continuing the beam by reinforcing at least end part of an H-shaped structural steel main body with reinforced concrete and inducing a prestress in a reinforced concrete reinforcement part by a post tension method. The prestressed end-reinforced hybrid beam according to an embodiment of the present invention includes: the H-shaped structural steel main body which comprises an upper flange, a lower flange which is parallel to the upper flange at an interval, and a length material in which a web connecting the upper and lower flanges forms an H-shaped cross section shape by being arranged to be vertical to the upper and lower flanges; an end reinforcing concrete which reinforces the cross section of both end parts of the H-shaped structural steel main body by being formed to surround the H-shaped structural steel main body in a predetermined section of both end parts of the H-shaped structural steel main body; and a sheath tube which is symmetrical to the upper part of the web of the H-shaped structural steel main body in the both upper sides of the cross section of the end reinforcing concrete, penetrates the end reinforcing concrete by being laid in the longitudinal direction of the H-shaped structural steel main body in parallel, and enables a PS strand to be inserted inside. |
