Description
技术领域technical field
本实用新型属于工程结构技术领域，具体涉及一种装配式钢结构半刚性节点。The utility model belongs to the technical field of engineering structures, in particular to an assembled steel structure semi-rigid node.
背景技术Background technique
随着近几年经济的发展，钢结构在国内有了很大程度上的发展。相比较于传统混凝土来说，这种结构具有重量轻、延性大，抗震性能好以及施工速度快等优点而得到了广泛的应用。节点设计在钢结构的设计中具有很重要的地位，通常钢结构的节点连接采用的是刚性连接或者铰性连接。铰性连接构造简单，适用于受力较小的情况下，其特点是在节点处能够自由转动，传递节点的竖向剪力，但不能传递弯矩。而对于刚性连接来说，省工省时使得材料能够充分利用，结构的整体性较好，在受力较大时，钢柱不只承受竖向剪力，还要承受弯矩。With the development of the economy in recent years, steel structures have developed to a large extent in China. Compared with traditional concrete, this structure has the advantages of light weight, high ductility, good seismic performance and fast construction speed, and has been widely used. Node design plays an important role in the design of steel structures. Usually, the node connections of steel structures are rigid connections or hinged connections. The hinged connection has a simple structure and is suitable for situations where the force is small. Its characteristic is that it can rotate freely at the node and transmit the vertical shear force of the node, but it cannot transmit the bending moment. For rigid connections, saving labor and time enables full use of materials and better structural integrity. When the force is large, the steel column not only bears the vertical shear force, but also bears the bending moment.
虽然刚性连接和铰性连接在很大程度上对分析和设计进行了简化，但实际情况节点的连接处于刚性连接和铰性连接之间。刚性连接延性大，产生较大的焊接残余变形和严重的残余应力或应力集中，容易发生脆性破坏，而铰性连接达不到“强节点，弱构件”的要求，浪费材料且不安全。Although rigid and hinged connections simplifies analysis and design to a large extent, the actual connection of nodes is between rigid and hinged connections. Rigid connections have high ductility, resulting in large welding residual deformation and severe residual stress or stress concentration, and are prone to brittle failure, while hinged connections cannot meet the requirements of "strong nodes, weak components", waste materials and are unsafe.
通过大量实验和数据表明，处于刚接节点和铰接节点之中的半刚性节点，具有较强的抗弯刚度，转动能力和变形能力，能够延长结构的自振周期。因此研究钢结构的半刚性节点的新形式，实现节点的延性就显得尤为重要。A large number of experiments and data show that the semi-rigid joints among the rigid joints and hinged joints have strong bending stiffness, rotation capacity and deformation capacity, and can prolong the natural vibration period of the structure. Therefore, it is particularly important to study the new form of semi-rigid joints of steel structures and realize the ductility of joints.
目前的半刚性节点一般为端板螺栓连接，在施工时需要将端板与梁端进行焊接，因而焊接质量将严重影响到节点的承载能力。The current semi-rigid joints are generally connected by end plate bolts. During construction, the end plates and beam ends need to be welded, so the welding quality will seriously affect the bearing capacity of the joints.
