摘要
本文从跨高比与挠度的关系入手,分析了用跨高比控制挠度目前尚存在的一些不合理因素,提出了根据钢筋应力来核算、修正跨高比的较为准确的计算方法,对实际工程具有一定的借鉴价值。
By dissecting the relation betwwen a ratio of span to height and deflection and analysing some non -rational factors in using span to height ratio to control deflection. this text puts forward the accurate counting method, based on the reinforcing bar stress. to check the ratio of span to height. It has some reference value to actual engineering a ratio of span to height deflection reinforcing bar stress concrete beam section.
