The invention discloses a shear parallel round hole mild steel plate high-
ductility mortar energy dissipation and shock absorption device and a manufacturing method. The device is composed of an upper connecting steel plate with round holes, a lower connecting steel plate, a lower connecting steel plate, a lower connecting steel plate, a lower connecting steel plate, a lower connecting steel plate, a lower connecting steel plate and a lower connecting steel plate, wherein the upper connecting steel plate is connected with a lower
flange of an H-shaped
steel frame beam; the soft
steel plates are welded between the upper connecting steel plate and the lower connecting steel plate and used for blocking
skin dog bone holes on the left side and the right side, the sheared parallel round hole soft steel plate, the front blocking soft steel plate and the rear blocking soft steel plate, the high-
ductility mortar is poured into a cavity between the soft
steel plates, and the upper connecting steel plate and the lower connecting steel plate are connected with the
steel frame-supporting structure through the high-strength bolt
system. Under the action of a strong earthquake, the front and rear plugging mild
steel plates-the sheared round hole parallel mild steel plates-the high-
ductility mortar cooperate to
resist earthquake, and after the high-ductility mortar is damaged and consumes more
earthquake energy, the front and rear plugging mild steel plates-the sheared round hole parallel mild steel plates shear, bend and deform to consume the
earthquake energy, so that the energy dissipation and shock absorption effects of the device can be effectively improved; and two anti-seismic defensive lines are provided.
