The invention relates to an energy dissipation device based on tensile yield deformation control and a working method, and belongs to the field of seismic resistance of constructional engineering structures. The energy dissipation device comprises a shell, a piston arranged in the shell, a push-pull rod connected to one side of the piston and extending out of the shell, a reset mechanism connected to the other side of the piston and energy dissipation elements connected to the two sides of the piston and connected with the shell; when an earthquake occurs, the energy dissipation elements can be pulled to yield so as to reduce the earthquake action input to a wood framework, and the reset mechanism can generate pulling force or pressure to reset the energy dissipation element. In the whole stage, the wood framework is always kept in an elastic state and is not damaged. The energy dissipation device is installed at the included angle of the beam-column connecting joint of the wood framework, and the purposes of
