一种用于建筑物的预应力框架结构
本发明属于预应力钢框架建筑结构技术领域，具体涉及一种用于建筑物的预应力框架结构；主梁、副梁和立柱设置成平行四连杆机构，并在主梁与副梁之间设置预应力锚索；四连杆机构能够在振动时产生形变，避免刚性破坏，预应力锚索能够在静态下使框架保持稳定，并能够在框架变形后驱使框架复位；由于预应力锚索设置在主梁与副梁之间，因此只要二者产生相对位移，预应力锚索就能够被拉伸以抵抗侧向载荷，不受框架倾斜方向限制，充分利用了锚索的载荷能力；另外，本发明用液压阻尼器代替机械阻尼器，阻尼大小更容易控制，且避免了阻尼器的机械磨损，提高了使用寿命。
The invention belongs to the technical field of prestressed steel frame building structures, and particularly relates to a prestressed frame structure for a building. The main beam, the auxiliary beam and the stand columns are arranged to be a parallel four-bar mechanism, and the pre-stressed anchor cables are arranged between the main beam and the auxiliary beam. The four-connecting-rod mechanism can deform during vibration, rigid damage is avoided, and the pre-stressed anchor cables can keep the frame stable in a static state and can drive the frame to reset after the frame deforms; due to the fact that the pre-stressed anchor cables are arranged between the main beams and the auxiliary beams, as long as the main beams and the auxiliary beams generate relative displacement, the pre-stressed anchor cables can be stretched to resist lateral loads and are not limited by the inclination direction of the frame, and the loading capacity of the anchor cables is fully utilized. In addition, the hydraulic damper is used for replacing a mechanical damper, the damping size is easier to control, mechanical abrasion of the damper is avoided, and the service life is prolonged.
