Shear Metal yield damper (MYD_V) is a displacement type damper that uses the plastic deformation of the steel in the plane to dissipate energy. It is generally composed of a core plate and a constrained steel plate. The constrained steel plate provides out-of-plane constraints for the core plate to ensure the core When the plate is subjected to in-plane shear, no out-of-plane buckling occurs.

Product advantages:
(1) MYD has a small yield displacement and enters a state where it can yield under small earthquakes. Energy consumption and the damper itself have certain rigidity, so it can provide a structure with both rigidity and damping;
(2) MYD is small in size, can be flexibly arranged between walls and windows, full of cultural atmosphere, and does not affect the use and function of the building facade;
(3) MYD not only consumes energy during small earthquakes, but also guarantees the hysteretic energy dissipation capacity under the design displacement of large earthquakes, with stable performance, good durability, and easy absorption of large earthquakes.

The connection between the energy dissipater and the main structure can generally be divided into wall type, support type, column type, portal type, and armpit type, etc., of which wall type connection and support type connection is commonly used.

Wall connection: set a piece on the upper and lower two floors of the main structural beam concrete cantilever wall, the cantilever wall (lower) and the upper (lower) beam are rigidly connected, (upper) embedded parts and connector plates (or steel members), damping The device is welded by buried connecting plates (steel members), and connected with the cantilever wall by bolt connection.

Takes the form of culture type connection arranged flexibly, can close to the main column side decorate, also can decorate in the two main pillars. Facilitate the hole in the doors and windows in the same box cloth or reserve, more easily in harmony with the architectural use requirements. Plug type connection of the body weight relative to a few bigger, additional load relative to a freshman Point, the wall of concrete, the construction cycle length. Wall connected to apply the new or existing concrete structures, especially in the layout of doors and windows when using demand.

Supporting type connection: two nodes at the bottom of the main beam position along the inclined above each stretch out bevel steel, the other end of the two steel support by connecting plate, forming a set of herringbone support, one end of the damper with herringbone support connection plate connection, the other end of the beam connected with the upper body. Also can adopt the way of extending from the upper nodes form V type support form, or in the steel beam-column node position up and down all the extended support, connect with the top of the damper in the upper part of the steel, the bottom connection in the lower steel support, the formation of x type connection.

Supporting type connection faults: decorate a form is relatively fixed, no coordination in architectural space using Pearson type connection. Advantage: use steel members join form, the construction period is shorter, lighter connection components, installation is convenient. Supporting type connection applies to the concrete structure, steel structure.
