摘　　要： 通过对8片体外预应力混凝土简支梁的静力加载试验,分析转向块及预应力筋形式不同对混凝土简支梁的提载效果影响,同时对其受力过程、破坏形态、承载力和变形情况进行全程记录及分析。试验结果表明,单转向块折线形体外预应力简支梁的提载效果较理想。 Eight simple supported concrete beams with external prestress were designed and tested. Effect of carrying capacity of external pre-stressed concrete beam in the difference of form of deviator and prestressed reinforcement was analyzed. The stressing process, recorded and analyzed throughout the mission.The unidirectional block and mansard was the ideal failure capacity, flexural capacity and deformation were test showed Beam of externally prestressed tendons with
