Description
技术领域 technical field
本发明属于建筑技术领域，特别是涉及一种混凝土框架节点的型钢加固方法及加固结构。 The invention belongs to the technical field of construction, and in particular relates to a method for reinforcing a section steel of a concrete frame node and a reinforcing structure.
背景技术 Background technique
节点是框架结构传力的枢纽，起着传递和分配内力、保证整体性的作用。在地震作用下，节点核心区经受着很大的水平剪力，一般约为柱子剪力的4～6倍，易产生剪切脆性破坏。另外由于反复荷载的作用导致钢筋粘结退化，发生钢筋锚固破坏，从而大大降低节点的强度、刚度和耗能能力。节点一旦破坏，会使结构处于极为不利的受力状态，甚至导致整个结构的倒塌。为了避免节点先于梁柱构件而破坏，钢筋混凝土框架结构抗震设计中以“强节点弱构件”作为设计原则。当框架节点由于设计、施工不当，或是使用功能、使用环境发生改变，或是对结构抗震要求提高等原因造成承载力不足，延性、刚度不够，或是抗震性能不足时，需对其进行加固补强。 Nodes are the hubs of force transmission in frame structures, which play a role in transmitting and distributing internal forces and ensuring integrity. Under earthquake action, the core area of the joint is subjected to a large horizontal shear force, generally about 4 to 6 times the shear force of the column, which is prone to shear brittle failure. In addition, due to the action of repeated loads, the bonding of steel bars is degraded, and anchorage damage of steel bars occurs, which greatly reduces the strength, stiffness and energy dissipation capacity of joints. Once the node is damaged, the structure will be in an extremely unfavorable stress state, and even lead to the collapse of the entire structure. In order to avoid the failure of joints before beam-column members, the design principle of "strong joints and weak members" is adopted in the seismic design of reinforced concrete frame structures. When the frame joints have insufficient bearing capacity, ductility, stiffness, or insufficient seismic performance due to improper design and construction, or changes in the use function and use environment, or the increase in the seismic requirements of the structure, it needs to be reinforced. reinforcement.
目前工程上对钢筋混凝土框架结构的抗震加固，通常是加大梁柱截面或粘贴补强材料等增大梁柱构件承载力，而很少或很难对结点进行加固，这种加固方法对框架结构抵抗“大震不倒”几乎没有任何作用。 At present, the seismic reinforcement of reinforced concrete frame structures in engineering is usually to increase the beam-column section or paste reinforcing materials to increase the bearing capacity of beam-column members, but it is seldom or difficult to reinforce the nodes. Resisting "survival after a big earthquake" has almost no effect.
加大截面加固法是采用增大混凝土框架节点的截面面积，以提高其承载力的一种加固方法。该方法提高了节点核心区的抗剪截面积，从而提高抗剪强度和刚度；加强了梁纵筋在节点区的锚固，能有效地避免梁端出现锚固破坏这一脆性破坏形式。在不影响使用功能的前提下，通过加大截面来加固节点是非常有效的，但其主要缺点是：梁柱表面均要凿毛，且湿作业多，加固施工难度大。 The method of enlarging the cross-section is to increase the cross-sectional area of the concrete frame joints to improve its bearing capacity. This method increases the shear cross-sectional area of the joint core area, thereby increasing the shear strength and stiffness; strengthens the anchorage of the beam longitudinal reinforcement in the joint area, and can effectively avoid the brittle failure form of anchorage failure at the beam end. On the premise of not affecting the function of use, it is very effective to strengthen the joints by enlarging the section, but its main disadvantages are: the surface of the beams and columns must be chiseled, and there are many wet operations, so the reinforcement construction is difficult.
粘贴碳纤维加固法即是在混凝土构件外部粘贴碳纤维材料，以提高承载力和满足正常使用的加固方法。其明显的技术优势主要体现在：高强高效，充分利用FRP高强度、高模量的特点来提高结构及构件的承载力和延性，改善其受力性能、耐腐蚀性能及耐久性；FRP材料的化学性质稳定，不与酸碱盐等化学物质发生反应，不增加构件的自重和体积，便于施工。 The carbon fiber reinforcement method is to paste carbon fiber materials outside the concrete members to improve the bearing capacity and meet the normal use. Its obvious technical advantages are mainly reflected in: high strength and high efficiency, making full use of the characteristics of FRP's high strength and high modulus to improve the bearing capacity and ductility of structures and components, and improve their mechanical performance, corrosion resistance and durability; It has stable chemical properties, does not react with chemical substances such as acid, alkali and salt, does not increase the weight and volume of components, and is convenient for construction.
有关试验研究表明，粘贴碳纤维加固节点时碳纤维对节点受力性能的作用主要表现在以下两个方面： Relevant experimental studies have shown that the effect of carbon fiber on the mechanical performance of nodes when pasting carbon fiber reinforced nodes is mainly manifested in the following two aspects:
首先，约束了节点核心区混凝土的横向体积膨胀，限制节点核心区混凝土的开裂和裂缝的进一步发展，给核心区混凝土以环向压力，间接提高混凝土的抗压强度。 First of all, it constrains the lateral volume expansion of the concrete in the core area of the joint, limits the cracking and further development of the concrete in the core area of the joint, gives the concrete in the core area a hoop pressure, and indirectly increases the compressive strength of the concrete.
其次，直接承担外荷载，参与节点的抗剪，限制节点核心区混凝土的剪切变形。节点的剪切变形同梁纵筋的粘结滑移变形一样，会使得荷载位移滞回曲线产生捏缩，耗能能力降低，使结构的位移加大。大量试验证明，在钢筋混凝土框架结构的层间位移中，节点的剪切变形要占到40%～60%，因此，无论从耗能还是减小变形的角度来考虑，都应该限制节点的剪切变形。 Secondly, it directly bears the external load, participates in the shear resistance of the joint, and limits the shear deformation of the concrete in the core area of the joint. The shear deformation of the joint is the same as the bond-slip deformation of the longitudinal reinforcement of the beam, which will cause the load-displacement hysteretic curve to pinch, reduce the energy dissipation capacity, and increase the displacement of the structure. A large number of tests have proved that in the interstory displacement of reinforced concrete frame structures, the shear deformation of joints accounts for 40% to 60%. Therefore, no matter from the perspective of energy consumption or deformation reduction, the shear deformation of joints should be limited. Cut deformation.
粘钢加固法是在构件表面用特制的建筑结构胶粘贴钢板，以提高结构承载力的一种加固方法。采用粘钢加固梁柱节点，即在梁柱组合体节点区域的梁端、柱端或核心区粘贴有抗弯、剪的钢板或角钢，以提高节点区的抗剪承载力或改善节点核心区的受力性能。 The bonding steel reinforcement method is a reinforcement method that uses a special building structure adhesive to paste steel plates on the surface of components to improve the structural bearing capacity. Beam-column joints are reinforced with bonded steel, that is, the beam end, column end or core area of the beam-column combination is pasted with bending-resistant, shearing steel plates or angle steels to improve the shear bearing capacity of the joint area or improve the joint core area stress performance.
该加固方法具有以下优点：被加固构件基本不受损失，可以充分发挥原物件的作用；外粘钢板厚度小，加固后自重增加小；加固后构件的外形尺寸变化不大，对建筑功能影响较小。同时，粘钢板加固也存在以下缺点：钢材为解决防腐蚀问题，表面应作一定厚度的面层，从而也改变了构件截面尺寸，给装修带来困难；钢板搭接锚固较为麻烦，工程量较大。因此开发混凝土框架节点加固方法加固的简单有效方法十分必要。 This reinforcement method has the following advantages: the reinforced components are basically free from loss, and can give full play to the role of the original object; the thickness of the externally bonded steel plate is small, and the increase in self-weight after reinforcement is small; the external dimensions of the reinforced components do not change much, and have little impact on building functions. Small. At the same time, there are also the following disadvantages in the reinforcement of bonded steel plates: in order to solve the problem of anti-corrosion, the surface of the steel should be covered with a certain thickness, which also changes the cross-sectional size of the component and brings difficulties to the decoration; big. Therefore, it is necessary to develop a simple and effective method of strengthening concrete frame joints.
