| 摘 要： | 给出了20根矩形截面无粘结部分预应力砼迭合梁(其中2根为对比梁)极限承载力的试验成果.在此基础上,结合无粘结部分预应力砼梁及普通砼迭合梁的已有成果,提出了一套无粘结部分预应力砼迭合梁正截面承载力计算公式.经试验结果验证可知,这些公式计算精度较高,可满足工程设计要求.

| Abstract: | This paper presents the experimental results of the ultimate moment of 20 unbonded partially prestressed concrete composite beams with rectangular cross-sections. According to the research results, an ultimate moment calulation method of unbonded partially prestressed concrete composite beams is proposed. Com-pared with the experimental results, the offered formula is in highly precision. Therefore, it can be used in engineering design directly. |
