【Abstract】 This paper presents the analytical formulas of random responses of systems with finite free degrees under multisupport interference by applying the theory of random vibration and space- interrelated ground motion model. Examples show that in large -span systems with finite free degrees there is a great difference between the response under the identical ground motion and that under the space -interrelated ground motion. Therefore, the differential motions among supports of large -span systems can not be neglected.更多还原
