| 摘 要： | 本文先介绍了受一定荷载作用的钢筋混凝土简支梁进行高温火烧试验及其残余力学性能测定等情况;然后将这些梁与常温下的同类简支梁进行比较.文中分析和探讨了荷载、高温等因素对钢筋混凝土梁的强度、变形和裂缝等性能的影响.研究表明,受较大荷载作用的梁,在经受较高的温度以后,强度与变形等力学性能将有较大的改变.

| Abstract: | In this paper, the tests of high temperatures on simply supported reinforced concrete beams under loads are presented at first. After the tests, residual mechanical behaviors of these beams have been measured and compared with those of the same kind of beams at ambient temperature. Effects of the factors, such as load, temperature, and so on, on the strength, deformation and crack, are analysed and discussed. It is showed that, when a beam is subjected to a higher temperature under a bigger load, the changes of its mechanical properties are notable. |
