摘　　要：在建筑结构中采用混凝土 (RC/PC)开孔梁 ,使各种管道、线路等从构件孔中穿过 ,可以有效地节约建筑空间 作者在前期工作的基础上 ,通过 1 0根足尺混凝土 (RC/PC)开孔梁的实验研究 ,对混凝土 (RC/PC)开孔梁的强度、刚度、变形、裂缝开展等特性进行了详细的探讨 研究中考虑了静定梁、超静定梁、单孔、双孔、普通混凝土梁、预应力混凝土梁、对比试验、仿真试验、实测试验等多种情况 。Concrete (RC/PC) beams with large openings through which all kinds of accessory facilities are installed are used in architectural structures.They make it possible to lower the height of architectural structure and to lighten the weight of it, so as to achieve good economic and social benefits. Based on the work experience of the authors,this paper analyzes the characteristics of concrete (RC/PC) beams with large openings in strength, rigidity, deformation, and cracking through an experimental study of 10 concrete (RC/PC) beams (the cases of single opening, double openings, and etc. considered) .Some proposals for designing and calculating methods of concrete beams with large openings are given.
