【摘要】 提供两个高效而实用的FORTRAN程序(例行子程序形式),用于对称三对角矩阵的两个计算问题(其一是线性代数方程组的求解,其二是广义特征值问题的计算)。在工程应用中,它们可用于多层建筑的振动特性分析、反应谱法地震变形计算、Pushover静力推覆分析和时程法地震反应分析等问题中。更多还原

【Abstract】 This paper provides two FORTRAN subroutines for the two computational problems of the symmetric tridiagonal matrix (solution of the system of liner algebraic equations, and computation of the generalized eigenvalues and eigenvectors). The two subroutines can be utilized in the analysis of vibration characteristics of multistory buildings, and their seismic deformation computation by the response spectrum method, the push-over analysis, and the seismic response analysis by various time history methods. The two subroutines adopt special computational methods. Therefore, they have high efficiency and are very practical.更多还原
