Abstract:

The elementary principle, the structure of the program, the main functions and characteristics as well as its running environment about the linear fluid-solid interactiondynamic analysis program-FSIAP 92 are shortly introduced in this paper. A simpleflow chart for the program is drawn to explain the relations between each principal function blocks of subroutine. Two numerical examples, a one-dimensional fluid pressure wave problem transmitting along a water pipe of 100m long and a dynamic response problem of a dam-water system excited by a given horizontal ground motion, are presented to demonstrate the applications of the program-FSIAP 92. Comparisons of thecomputational results with the corresponding theoretical solutions show that the FSIAP92 are very attractive.
