Background
In the anti-continuous collapse design of the structure, the node is the most important part, after the vertical bearing component is damaged, no matter the 'alternative path method' paying attention to the overall performance or the 'tie strength method' paying attention to local components, the node plays an important role in the anti-continuous collapse of the structure, whether the node is effective and reliable or not is determined, whether an effective internal force redistribution path is arranged inside the structure or not is determined, and whether the 'suspension cable effect' can be effectively formed in the structure in a large deformation state or not is determined to redistribute the internal force, so that the combined node in the existing building and the newly-built building needs to be reinforced to improve the anti-collapse capability of the structure. When a traditional combined node is reinforced, the bearing capacity and rigidity of the node are improved by increasing the section size of a component so as to achieve the purpose of improving the collapse resistance of the node, but the improvement of the bearing capacity of the node is particularly to improve the rigidity of the node, so that the rigidity of the reinforced node is changed, the performance of the reinforced node is not matched with that of the node which is not reinforced, and the internal force distribution of the structure under normal use load is influenced. Therefore, a strengthening method which does not affect the rigidity of the node is needed.
