Abstract
The utility model discloses an RSC combined node continuously cut on a web and partially cut on flanges. The RSC combined node comprises a reinforced concrete column and a steel beam vertically penetrating through the reinforced concrete column, wherein the steel beam is formed through vertical connection of a steel beam web and the steel beam flanges at two end portions of the steel beam web. The reinforced concrete column is composed of a longitudinal steel bar, a plurality of layers of horizontally-distributed stirrups attached to and surrounding the periphery of the longitudinal steel bar, and poured concrete in the column. The steel beam flanges vertically penetrating through the reinforced concrete column are partially cut, the stirrups penetrate through a node web connected with the steel beam web, and two ends of the node web are vertically provided with surface bearing plates. A core node is formed by the longitudinal steel bar in the reinforced concrete column, the stirrups around the longitudinal steel bar, the two surface bearing plates, the node web and the partially-cut extending ends of the steel beam flanges. A steel web of the core node mainly bears shearing force, and the extending ends of the steel beam flanges and the surface bearing plates limit core node concrete so that shearing-resistant bearing force is greatly improved.
Description
Technical field
The utility model relates to the Steel concrete combining structure, particularly a kind of reinforced concrete post-girder steel combined joint, namely web continuously, the RCS combined joint of edge of a wing Partial Resection.
Background technology
Reinforced concrete post-girder steel composite frame structure (composite frame consisting of Reinforced Concrete column and Steel beam, be called for short RCS) different materials of having given full play to steel concrete and steel member advantage separately is a kind of low cost, high efficiency form of structure.Reinforced concrete post-steel beam structure system is a kind of succession and the development of pure steel structure and reinforced concrete structure, has more excellent stress performance and economy.Generally speaking, compare with pure steel structure, the compressive property of reinforced concrete post is good, and rigidity is large, and durability and refractoriness are good, thus saving steel, the stability of increase structure; Compare with reinforced concrete structure, the anti-bending strength of girder steel is good, and quality is light, easy construction, and the sectional dimension of members less, thus can increase effective usage space, accelerating construction progress.Can also alleviate simultaneously the superstructure deadweight, reduce the caused structural internal force of geological process etc.Yet because connected node structural form and stress performance in this form of structure are all more complicated, only the U.S. and Japan allow to adopt this form of structure in Practical Project at present.Also do not adopt the case history of RCS composite frame structure in the civilian construction structure of China.Analyzing reason, is mainly present RCS combined joint or the mode that adopts girder steel to connect, and namely girder steel continues to pass through reinforced concrete post, because the girder steel edge of a wing area of this node is larger, make the vertical muscle effective force in post, must bore a hole on the edge of a wing, cause constructional difficulties; And the larger edge of a wing also can cause concrete cast difficulty, also can affect construction speed; It is the mode that post connects, node is passed in the longitudinal reinforcement perforation that is reinforced concrete post, girder steel takes adequate measures (welding or bolt connect) to be connected in node both sides, because the girder steel of this node is discontinuous, often easily causing the Sudden failure of weld seam or the catastrophic failure of bolt, is not all desirable ductile fracture.Therefore, how research improves the structural form of RCS combined joint, can guarantee globality and the power transmission validity of joints, can facilitate concrete cast again, accelerating construction progress just becomes and applies reinforced concrete post-girder steel composite frame structure problem demanding prompt solution.
Summary of the invention
