STRONG COLUMN AND WEAK BEAM NODE STRUCTURE OF REINFORCED CONCRETE FRAME
The utility model discloses a strong column and weak beam node structure of reinforced concrete frame, comprising a reinforced concrete frame beam, reinforced concrete frame columns, and frame beam end reinforced sections, wherein the frame beam end reinforced section is the part where the beam section of the reinforced concrete frame beam close to the reinforced concrete frame column in a certain range is locally enlarged and the reinforcing bars is locally reinforced; the local enlargement of the beam section refers to the enlargement in the width of the beam section and the enlargement in the height of the beam section within the range; the top surface of the end reinforced section is flush with the top surface of the connected frame beam. The advantageous effects of the invention are: the concrete frame node can be strengthened; the frame beam has a relatively weakened bearing capacity at the section; under the action of a large earthquake, the plastic hinge position of the frame beam leaves the node area, forming a beam hinge failure mechanism, so as to achieve the design purpose of "strong column and weak beam".
