中文摘要：
为了考察预应力内置H型钢混凝土简支组合梁的承载力，裂缝分布与开展及变形发展情况，进行了5根预应力内置H型钢混凝土简支组合梁的设计、制作和试验，根据考察内容获得了相关试验数据，通过分析试验数据，提出了该种组合梁的正截面受弯承载力计算公式、裂缝宽度及刚度计算公式。
英文摘要：
In order to get the carrying capacity, distribution and growth of crack as well as the deformation of simple prestressed H-steel reinforced concrete beam, 5 specimens were designed, manufactured and tested in this paper. Relative data were obtained and analyzed. The calculation formulas of carrying capacity, crack width and stiffness for the beam were presented based on the analysis of these data.
