摘　　要：基于前期研究及《预应力混凝土结构设计规范》（JGJ 369—2016）的编制,主要介绍了后张有粘结预应力型钢混凝土框架梁的抗弯承载力、刚度、裂缝计算方法、规范中计算公式的来源以及基于延性控制的竖向抗震设计方法。在塑性及延性性能基础上给出了型钢、预应力筋及受力筋配置量的参考值,对于该结构基于性能的优化设计具有参考作用。最后对该结构形式的不足与发展提出建议,以期对其推广起到积极作用。Based on previous studies and the preparation of the Code for design of prestressed concrete（ JGJ 369—2016）,the follows of bonded post-tehsioned prestressed steel reinforced concrete（ PSRC） frame beam were introduced including the calculation method of flexural capacity,stiffness and crack,the calculation formula adopted in the code,and the vertical seismic design method based on ductility control. On the basis of ductility and ductility performance,the configuration reference values of steel,prestressed tendons and ordinary reinforcement were given,which may provide a reference on optimization design based on performance for PSRC frame beam. Finally,some suggestions were mentioned on the shortcomings and the development of PSRC structure,which can play a positive role in promotion.
