RANDOM VIBRATION ANALYSIS OF LARGE COMPLICATED ENGINEERING STRUCTURES

摘要

In this paper, a calculation method of the random vibration for engineering structures is first studied. Furthermore, a program RVIBA that is used for analyzing the random vibration of large and complicated engineering structures is developed based on the finite program SAP84. The results of calculation examples show that the developed program possesses high precision and reliability. It provides an effective tool for the random vibration analysis of large structures and a valuable reference for developing the program of the random vibration analysis based on other large finite element programs.
