［摘要］消能減震結(jié)構(gòu)研究與設(shè)計(jì)中，往往忽略消能部件平面外的力學(xué)特性，可能為消能減震結(jié)構(gòu)埋下安全隱患。分析了雙向地震下消能部件的平面外變形模式，介紹了國內(nèi)外研究情況和相關(guān)規(guī)程、設(shè)計(jì)手冊(cè)對(duì)消能部件平面外力學(xué)特性的要求，給出以下建議：研究各類型消能部件在雙向地震作用下的力學(xué)特性及破壞模式，找到如消能器平面外剛度等關(guān)鍵力學(xué)指標(biāo)對(duì)消能部件平面外穩(wěn)定性的影響規(guī)律；建立各類型消能部件平面外穩(wěn)定性設(shè)計(jì)方法，以指導(dǎo)減震結(jié)構(gòu)分析和設(shè)計(jì)；研究能釋放消能器平面外受力或變形的柔性連接構(gòu)造措施。

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.

Keywords:energy dissipation device; connection; out-of-plane; stability
