传递矩阵法在建筑工程中的研究现状

On Transfer Matrix Method in Construction Engineering

传递矩阵法是上世纪七八十年代兴起的由初参数法逐渐发展而来的一种简单有效的结构分析方法.它依据结构单元导出微分方程,再利用矩阵的简单相乘原理对结构进行动力学特征分析.由于建筑结构可以简化为链式结构,可以用传递矩阵法对建筑结构进行动、静态以及稳定性等分析,加之传递矩阵法的易编程,快捷,精度高等特性,因此传递矩阵法在建筑工程领域应用十分广泛.

Transfer matrix method evolved by the initial parameter method arose in the 1970 s. It is a simple and effective method for structural analysis. Based on the structural unit derived from differential equations,the structural dynamic characteristics are obtained from simple multiplying principle of the matrix. Because the building structure can be simplified to chain structure,dynamic and static state of building structure can be analyzed.Therefore,the transfer matrix method is widely used in construction engineering.
