摘　　要： 通过4组8个混凝土结构足尺试件的单调静力加载试验,进行了新型装配整体式混凝土结构叠合主次梁节点及现浇对比节点的模型试验研究。试验表明:试件截面应变基本满足平截面假定,破坏源于节点区附近次梁的受弯破坏,叠合试件中预制部分与现浇部分之间基本未出现滑移,按规范公式计算叠合试件抗裂能力和抗弯承载力是安全的。 Monotonic static tests were conducted on the four groups of full-scale cast-in-place（RC） nodes and composite（PC） ones of beam-and-girder which were composed of precast inverted T-girder.The contrast experiments indicated that both of the PC and RC nodes failed in beams bending;the assumption of plane section was basically fulfilled in every kind of PC beams throughout the whole testing process;the values of crack-resisting and bending-resisting bearing capacity.Which were calculated according to China codes were safe.
