Problems solved by technology
As the key load-bearing components of building structures, nodes often meet the requirements of strong nodes and weak components according to seismic codes. However, in traditional building structures, nodes are often the first to yield and produce plastic hinges under seismic loads, thereby consuming seismic energy. The structure is more prone to damage or even collapse

Embodiment Construction
[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] Such as Figure 1 ~ Figure 4 As shown, a buckling-resistant mild steel second-order reinforced steel beam-column node includes a horizontally arranged node steel beam 16 and a node steel column 14 that is vertically arranged and fixedly connected with the node steel beam 16, and the node steel beam The two ends of 16 are connected wit...

The invention discloses a anti-buckling mild steel secondary reinforced steel beam-column joint. The anti-buckling mild steel secondary reinforced steel beam-column joint comprises an arc-shaped middle anti-buckling steel pipe, wherein arc-shaped outer anti-buckling steel pipes are arranged at two sides of the middle anti-buckling steel pipe respectively, and the middle anti-buckling steel pipe and the two outer anti-buckling steel pipes are connected into a whole through low yield point perforated mild steel; a built-in I-steel is installed in the anti-buckling steel pipe, one end of the I-steel is fixedly connected with the steel beam, and the other end of the I-beam is connected with a fixed cylinder sleeve, limited rubber is installed in the fixed cylinder sleeve, and mortar is injected into the anti-buckling steel pipe. According to the anti-buckling mild steel secondary reinforced steel beam-column joint, energy is consumed by plastic deformation of the low yield point mild steelat the initial loading stage, and when the I-steel reaches the limiting rubber constraint position, the arc-shaped anti-buckling support starts to carry out secondary energy consumption. The beam-column joint is convenient to process, easy to install and disassemble, environment-friendly, the production efficiency is improved, the structural form is simple, the energy dissipation capacity of thejoint is obviously enhanced, and the earthquake resistance and collapse resistance of the structure are improved.
Description
technical field [0001] The invention relates to a beam-column joint, in particular to a buckling-resistant mild steel second-order reinforced steel beam-column joint. Background technique [0002] In recent years, prefabricated structures have been widely used in industry development due to their advantages of high production efficiency, convenient assembly, green energy saving and environmental protection. At the same time, passive damping devices are widely used in building structures at home and abroad because of their low cost and good damping effect. As the key load-bearing components of building structures, nodes often meet the requirements of strong nodes and weak components according to seismic codes. However, in traditional building structures, nodes are often the first to yield and produce plastic hinges under seismic loads, thereby consuming seismic energy. As a result, the structure is more likely to be damaged or even collapsed. [0003] Therefore, how to desi...
