摘要
对于钢筋混凝土结构 ,现行规范通常采用以截面为分析对象的极限状态法 (即截面内力法 )进行设计。此方法对于结构的有些区域比较适用 ,但对有些区域就不合理 ,甚至不能用此方法设计。近年来 ,欧美国家提出一种在有限元分析基础上适用于混凝土结构各部位配筋设计的拉压杆模型法 ,但国内对此方法还缺乏系统研究。该文主要介绍它的设计原理、一般准则及具体步骤 ,以引起国内学者的关注与兴趣 ,共同研究与探讨 ,推动我国在此方面的研究工作。
In current Chinese code, reinforced concrete structures are normally designed with the limit state design method in which critical cross sections are analyzed. The method is applicable and rational for certain parts of structures very well, but it is not suitable for some parts of structures, and even some parts of the structure can not be designed by means of this method at all. In recent years the Strut-and-Tie model method is proposed and applied in the European and American codes, which is based on the finite element analysis and is suitable for all types and all parts of structures. However, there is few study of this new method in China. In order to evoke domestic scholars` interest in this topic, the design principle, general criterion and general design procedure of this method are introduced in this paper.
