摘要
研究设计２个无粘结部分预应力扁梁节点，并进行低周反复加载试验。根据试件的裂缝开展过程，纵筋和箍筋的应变发展，预应力筋应变增长，以及试件的实测Ｐ－Δ曲线，着重研究了无粘结部分预应力扁梁节点梁端和核心区的受力特性以及抗震性能。
Two partially unbonded prestressed flat beam column end joints were designed,and the low reversed loading test was carried out.The cracking process of the members, the strain development in non prestressed bars and prestressed tendons and the P Δ curves were measured to analyze the shear strength and seismic behavior of the end joints.
