Description
技术领域 technical field
本实用新型涉及一种梁柱节点，特别涉及一种适用于多高层框架钢结构工程的装配式耗能型梁柱节点，属于建筑结构工程技术领域。 The utility model relates to a beam-column joint, in particular to an assembled energy-consuming beam-column joint suitable for multi-high-rise frame steel structure engineering, and belongs to the technical field of building structure engineering.
背景技术 Background technique
近几年，随着建筑科学技术的发展，钢结构以其优异的性能广泛应用于多高层结构、大跨空间结构及桥梁结构中。由于地质灾害的不断发生，专家学者对钢结构建筑的抗震性能越来越关注和重视，因此，在结构的设计阶段，对结构采取合理必要的防震措施显得尤为重要。在多高层钢结构建筑中，最为薄弱和危险的部位通常是梁柱节点处。当结构遭遇地震时，尤其是烈度较大的破坏性强震时，结构中的梁柱节点部位常因刚度较大，不能够吸收和消耗地震能量，而造成节点处产生过大屈曲变形，甚至发生脆断，严重威胁人们生命和财产安全。 In recent years, with the development of building science and technology, steel structures have been widely used in multi-high-rise structures, long-span space structures and bridge structures due to their excellent performance. Due to the continuous occurrence of geological disasters, experts and scholars pay more and more attention to the seismic performance of steel structure buildings. Therefore, it is particularly important to take reasonable and necessary anti-seismic measures for structures in the design stage of structures. In multi-story steel structure buildings, the weakest and most dangerous parts are usually the beam-column joints. When a structure encounters an earthquake, especially a destructive earthquake with high intensity, the beam-column joints in the structure are often unable to absorb and consume seismic energy due to their high stiffness, resulting in excessive buckling deformation at the joints, even Brittle fracture occurs, which seriously threatens people's life and property safety.
目前，在实际钢结构工程中，钢结构梁柱节点的设计基本上依旧遵循过去国内外遵循的设计原则“强节点弱构件”，通过焊接、高强螺栓或焊接及螺栓结合的形式，将梁柱节点制作成刚性连接或者铰接。该种形式的连接节点不具备较强的变形和耗能能力，无法确保变形耗能区域转移到梁端部位。同时，由于梁柱节点部位存在严重的应力集中现象，当承受地震荷载时，极易发生脆性断裂破坏，造成结构的垮塌。尽管目前国内外专家学者针对以上问题提出了许多针对性措施，如：削弱两端截面或端部采用扇形构造等方式，但以上方式不但造成结构的整体承载力下降，同时还可能引发梁端部的局部稳定问题。 At present, in the actual steel structure engineering, the design of beam-column joints of steel structures basically follows the design principle of "strong joints and weak members" in the past at home and abroad. Through welding, high-strength bolts or welding and bolts, the beam-column Nodes are made as rigid connections or hinges. This type of connection node does not have strong deformation and energy dissipation capabilities, and cannot ensure that the deformation energy dissipation area is transferred to the beam end. At the same time, due to the serious stress concentration phenomenon at the beam-column joints, when subjected to earthquake loads, brittle fractures are prone to occur, resulting in the collapse of the structure. Although experts and scholars at home and abroad have proposed many targeted measures for the above problems, such as: weakening the cross-section at both ends or adopting fan-shaped structures at the ends, the above methods not only cause the overall bearing capacity of the structure to decrease, but also may cause beam ends to be damaged. local stability problem.
