［摘要］支墩型连接是消能减震结构常用的连接方式。针对消能子结构设计方法不统一、不可靠及设计结果不合理的问题，对支墩型消能子结构提出弹性设计方法。建立子结构弹性设计验算关系式，给出弹性设计验算关系式中各参数的取值方法，推导阻尼器对支墩型子结构产生的附加内力。以某框架结构为例，对弹性设计方法及新疆、云南设计方法设计的子结构进行构件极限承载力验算。结果表明：满足弹性设计验算关系式的消能子结构可以满足《建筑消能减震技术规程》（JGJ 297—2013）第6-4-2条关于子结构设计的有关要求；仅提高设计准则的中震设计方法和提取大震下构件内力进行承载力复核的方法没有全面考虑《建筑消能减震技术规程》（JGJ 297—2013）第6-4-2条有关规定，设计结果不满足要求。

Abstract:Pier-type connection is a common connection method of energy-dissipated structures. Aiming at the problems that the design methods for energy-dissipated substructures are not unified and unreliable and the design results are unreasonable, elastic design method of pier-type energy-dissipated substructures was proposed. Elastic design check relationship formula of substructures was established, and the methods of determining each parameter in the relationship formula were given as well, and the additional internal force generated by the damper to the substructures with pier-type connection was deduced. A reinforced concrete frame was taken as an example to conduct ultimate bearing capacity check of substructures designed by the elastic design method and design methods of Xinjiang and Yunnan Provinces. The results indicate that the energy-dissipated substructure that satisfies the elastic design check relationship formula can meet the relevant requirements of the substructure design in Article 6-4-2 of Technical specification for seismic energy dissipation of buildings (JGJ 297—2013). The design method which only improves the design criteria under the fortification earthquake and the method which extracts the internal force of components under the rare earthquake to check the bearing capacity do not fully consider the relevant provisions of Article 6-4-2 of  Technical specification for seismic energy dissipation of buildings (JGJ 297—2013), and the design results do not meet the requirements.
