Special-shaped concrete filled steel tube column-I-shaped steal beam framework node
The invention discloses a special-shaped concrete filled steel tube column-I-shaped steal beam framework node. The invention aims at solving the problems of strict anti-seismic design requirement and poor anti-seismic performance of a conventional reinforced concrete special-shaped column framework node, improving design indexes of the maximum use height and the column shaft compression ratio of a special-shaped column structure house and further promoting the use of the special-shaped column structure in a high-fortification-intensity region, and provides the special-shaped concrete filled steel tube column-I-shaped steal beam framework node. In order to reduce the relatively high steel consumption of the special-shaped concrete filled steel tube column and framework node and solve the local buckling problem of a column steel tube and a node steel plate, construction measures of installing pulling steel bar reinforcing ribs inside a special-shaped steel tube and installing vertical rib plates in beam column connecting positions are used; the constraint effect of the special-shaped steel tube on the concrete is improved; the bearing capability of a special-shaped concrete filled steel tube is further improved; meanwhile, the capability of the node for transmitting the internal force of the beam post is improved; and the anti-seismic capability of the special-shaped column framework node is further improved.
