| 摘 要： | 在养护期内,钢筋混凝土梁中钢筋应力受到很多因素的影响,通过试验表明各种因素综合的结果是使钢筋产生压应力,主要原因是混凝土收缩导致钢筋受到压缩,且压应力的最大值可达17.6 MPa。

| Abstract: | The steel stress of concrete beam during construct procedure is influenced by many factors.The test data shows that the final effect of the factors result in steel compressive stress.The main reason is that shrink of the concrete makes the steel compressed,and the maximum compressive stress value can reach to 17.6 MPa. |
