Description
技术领域technical field

背景技术Background technique
装配式钢-混凝土组合连梁是一种新型的连梁结构形式，其中的工字型钢梁和钢筋混凝土板均为预制构件，可在现场直接安装，施工速度较快且构件制作质量高。通过拧紧螺帽对两端带螺纹的拉杆进行张拉，可以保证两侧钢筋混凝土对工字型钢梁的腹板形成有效的侧向支撑，从而使得在大震作用下，工字型钢梁的腹板剪切屈服而不发生屈曲现象，大大提高工字型钢梁的剪切耗能能力。通过在拉杆和钢筋混凝土板间设置橡胶管，使得工字型钢梁在受力时与钢筋混凝土板间可产生一定量的界面滑移，保证了钢筋混凝土板在面内不受力，只对工字型钢梁腹板产生侧向约束作用。The prefabricated steel-concrete composite coupling beam is a new type of coupling beam structure, in which the I-shaped steel beam and the reinforced concrete slab are prefabricated components, which can be directly installed on site. The construction speed is fast and the component production quality is high. By tightening the nuts and tensioning the threaded tie rods at both ends, it can be ensured that the reinforced concrete on both sides forms an effective lateral support for the web of the I-shaped steel beam, so that under the action of a large earthquake, the I-shaped steel beam The web shear yields without buckling, which greatly improves the shear energy dissipation capacity of the I-shaped steel beam. By setting the rubber tube between the tie rod and the reinforced concrete slab, a certain amount of interface slip can be generated between the I-shaped steel beam and the reinforced concrete slab when the force is applied, ensuring that the reinforced concrete slab is not stressed in the plane, only for The I-shaped steel beam web produces lateral restraint.
传统钢连梁在荷载作用下钢板极易发生屈曲导致承载力迅速降低，而传统混凝土连梁在往复荷载作用下易开裂且耗能能力不足，因此研制装配式钢-混凝土组合连梁来同时克服传统钢连梁和传统混凝土连梁的缺点具有重要的意义和应用价值。The steel plate of the traditional steel coupling beam is prone to buckling under load, resulting in a rapid decrease in bearing capacity, while the traditional concrete coupling beam is prone to cracking and has insufficient energy dissipation capacity under the reciprocating load. Therefore, the fabricated steel-concrete composite coupling beam was developed to overcome the The shortcomings of traditional steel coupling beams and traditional concrete coupling beams have important significance and application value.
