By fitting of the original formula, a more scentific and reasonable simplified formula was presented.Keywords:reinforced concrete; circular section flexural member; reinforcement calculation; polynomial fitting作者簡介:吳明軍,教授,高級工程師,Email:346116459@qq.com。參考文獻[1] GB50010—2002混凝土結(jié)構(gòu)設(shè)計規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2002.[2] 徐建. 一、二級注冊結(jié)構(gòu)工程師專業(yè)考試應(yīng)試題解[M].2版.北京:中國建筑工業(yè)出版社,2006.[3] 孫芳垂.一級注冊結(jié)構(gòu)工程師專業(yè)考試復(fù)習(xí)教程[M].3版.北京:中國建筑工業(yè)出版社,2004.
