Abstract:In the research and design of energy dissipation structures, the out-of-plane mechanical characteristics of energy dissipation devices are often neglected, which may be a potential safety hazard of energy dissipation structures. Deformation modes of energy dissipation devices under bidirectional seismic were analyzed and the requirements for mechanical properties of energy dissipation devices at home and abroad, related regulations and design manuals were introduced. The advices are as follows: mechanical properties and failure modes of all kinds of energy dissipation devices under bidirectional seismic should be studied. The influence law of some key mechanical indexes on the out-of-plane stability of energy dissipation devices needs to be found, such as out-of-plane stiffness of energy dissipation devices. Design method for out-of-plane stability of all types of energy dissipation devices should be established to guide the analysis and design of energy dissipation structures. The flexible connection construction measures that can release the external force or deformation of the energy dissipation devices should be studied.
