摘　　要：结构局部区域(应力、应变被干扰区域)常常是结构的关键部位。采用压杆-拉杆这种宏观力学模型方法可避开复杂的有限元计算,就可明确这类区域的主导传力路径,进而采取相应的构造处理措施,保证结构安全。本文论述了压杆-拉杆模型方法的基本概念、基本原理、建立方法、计算方法和应用示例,为解决结构局部区域钢筋合理布置提供了一种有效手段。The structural disturbance regions where the stress and strain distribution is significantly nonlinear are usually key positions of the structure. We can confirm the passing force dominant route of those regions using the method of macro mechanics modef （namely strut-and-tie model） ,and we may adopt corresponding detailing measures to guarantee the construction safety. The paper discusses the basic concept and principle, establishing and calculation methods of the strut-and-tie model, and gives its application examples. So the method of strut-and-tie model provides the effective means to solve reasonable reinforcement scheme of the structural disturbance regions.
