一、前言直角式悬挑楼梯(以下简称悬梯)因造型轻巧、美观,故在大型公共建筑中应用较为广泛。《建筑结构》1983年第3期曾介绍过筒井助幸写的关于《钢筋混凝土直角式悬梯的应力计算方法》一文。该文发表后,广大设计工作者颇感兴趣,曾进行过一些分析和研究。笔者认为,该文将梯台与梯段之间的折线梯板简化为直线梯板计算,却大大影响了实际内力的数值,有个别内力(如:M_T见后面例题)的某些断面甚至误差达6倍以上。笔者曾对类似的
I. INTRODUCTION Right-angled cantilevered staircases (hereinafter referred to as cantilevered ladders) are more widely used in large-scale public buildings due to their lightweight and beautiful appearance. In the 3rd chapter of the “Architecture Structure” (1983), he introduced the article “The Method of Calculating the Stress of the Reinforced Concrete Right-Angle Ladder” written by Tsutsui Tsutomu. After the publication of this article, the majority of design workers were interested and had conducted some analysis and research. The author believes that the paper simplifies the calculation of the line-ladder between the terrace and the ladder to a straight-line ladder, but it greatly affects the value of the actual internal force, and there are certain sections or even errors of individual internal forces (such as: M_T see later example).
