为实现预制混凝土框架梁柱节点构造简单、性能可调、抗震性能良好，提出了一种新型干连接旋转摩擦耗能梁柱节点（DRFDBJ）。为了验证在PC框架结构中引入DRFDBJ的优点，提出了带DRFDBJ的PC框架（NPCF），并将其作为研究对象。本研究的重点在于（1）验证DRFDBJ和NPCF的优点，（2）揭示NPCF的关键设计参数，（3）开发NPCF的高效设计方法。通过对300个NPCF算例和3个钢筋混凝土整体框架算例的参数分析，重点研究了NPCF的抗震性能。在此基础上，确定了NPCF的关键设计参数为滑矩比ρ和滑矩分布型式SMDP。建议采用均匀累积SMDP作为NPCF抗震设计的合理SMDP。文中还提出了层数与ρ值之间的定量关系。在此基础上，提出了一种高效、兼容的NPCF设计方法，并成功设计了两种NPCF，进一步验证了DRFDBJ的优点和设计方法的可靠性。
To realize a beam-to-column joint for precast concrete (PC) frames with simple details, adjustable performance, and desirable seismic performance, an innovative dry-connected rotational friction dissipative beam-to-column joint (DRFDBJ) is proposed in this study. To validate the advantages of introducing DRFDBJs into PC frame structures, PC frame with DRFDBJs (NPCF) is proposed and considered as the research object. This investigation highlighted on (1) validating the advantages of the DRFDBJ and NPCF, (2) revealing the critical design parameters of the NPCF, and (3) developing a high-efficiency design method for the NPCF. Based on parametric analyses of 300 NPCF study cases and three monolithic reinforced concrete frame study cases, the seismic performance of NPCF is investigated with emphasizing on the control effect. Based on the results, the critical design parameters of the NPCF are identified to be sliding moment ratio (ρ) and sliding moment distribution pattern (SMDP). The rational type of SMDP for the seismic design of NPCF is recommended to be the uniform cumulative SMDP. The quantitative relationship between number of stories and rational value ofρis also recommended. Subsequently, a design method with high efficiency and compatibility is proposed for the NPCF, and two NPCFs are successfully designed using this method, thus further validating the advantages of the DRFDBJ and the reliability of the proposed design method.
