摘要
选用实际工程中应用较为普遍的K6型单层球面网壳作为重点研究对象,计算了多种工况(不同的矢跨比、荷载、支座条件)对网壳结构自振特性的影响,对K6型网壳结构的自振特性做了较为系统的研究,以得到K6型网壳结构的自振规律。
Taking K6 single-layer spherical shell which is common used in practical engineering as main research object, this paper calculates the influences of various operating conditions as different rise-span ratio, load and bearing condition on free vibration characteristics of shell structure, and systematically studies free vibration characteristics of K6 single-layer spherical shell, in order to gain free vibration rule of K6 shell structure,
