引言钢筋混凝土四边支承矩形板,在工程实践中应用颇广。设计时如考虑内力重分布的特性,按极限平衡法计算,较按弹性理论计算,钢筋用量可节省20～25%以上。我国早在五十年代即已采用这种先进的计算方法,收到了良好的效果。在过去流行较广的一些结构静力计算图表[1]和设计手册[2]中,有白文炳同志以格沃兹捷夫近似公式为基础所编制的钢筋面积计算表[4],在实 Introduction Reinforced concrete supports rectangular plates on all four sides and is widely used in engineering practice. When designing, consider the characteristics of internal force redistribution, according to the limit equilibrium method, compared with the elastic theory calculation, the amount of steel bars can save more than 20 ~ 25%. As early as the 1950s, China adopted this advanced calculation method and received good results. In some structural static calculation charts[1] and design manuals[2] that were popular in the past, there was a steel bar area calculation table [4] compiled by Comrade Bai Wenbing based on Gwastzeve’s approximate formula.
