Problems solved by technology
If the shell element simulation is directly used, the analysis of a single component is acceptable, but the analysis of the overall structure will be extremely difficult
On this basis, some scholars proposed to use multiple nonlinear connection elements for combined simulation, but it is necessary to set the shear force-lateral displacement relationship, axial force-axial displacement relationship, and bending moment-rotation angle relationship separately, and the parameter calculation is complicated. The implementation in general finite element software is cumbersome

The invention discloses an analysis method for simulating a shear type coupling beam damper. Four rod units are used for simulating the shear type coupling beam damper, one rod unit is used for simulating the shear stress performance of a core plate of the shear type coupling beam damper, two rod units correspondingly simulate the axial stress performance of an upper flange plate and a lower flange plate of the shear type coupling beam damper, and one rod unit is used for simulating the axial stress performance of the core plate of the shear type coupling beam damper. According to the analysis method for simulating the shear type coupling beam damper, only four rod units are adopted to simulate the shear type coupling beam damper, the unit type is simple, the number of the units is small, and the calculation speed is high.
Description
technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption in a building structure system, in particular to an analysis method for simulating a shear type coupling beam damper. Background technique [0002] The energy dissipation and shock absorption of building structures refers to the installation of appropriate energy dissipation components in the building structure. The energy dissipation components can be composed of energy dissipation shock absorption supports, steel plate dampers (walls), viscous dampers, etc. and supporting components. [0003] Coupling beams are widely used in shear wall structures and frame-tube structures, and are used as the first line of seismic defense for energy dissipation. Traditional reinforced concrete coupling beams have disadvantages such as low ductility and difficulty in repairing after damage. The engineering community proposes to use coupling beam dampers instead of traditional coup...
