| 摘 要： | 通过20根无粘结部分预应力砼梁(板)的试验,分析了影响无粘结部分预应力砼矩形截面受弯构件短期刚度的主要因素,根据试验结果,采用线性回归方法,得出了实用的短期刚度计算公式,经31根梁(板)59个试验值的验算,符合良好。

| Abstract: | Tests were performed on unbonded partially prestressed beams(slabs).The main factors which effecting short-time stiffncss for unbonded partially prestressed con- crete rectangular section flexural members are analysed in this paper.By the test results,the parctical short-time stiffness formula is proposed by means of linear regression analysis.The calculated results and 59 test results of 31 beams(slabs)comparcd show good agreement. |
