单层网壳的动力稳定
|
摘要
随着单层网壳的科研研究与工程应用,对其静力研究已趋完善,但对其动力性能特别是动力稳定的研究甚少,由于动力稳定研究远远滞后于网壳工程应用,因而其研究是当务之急,而对结构动力稳定研究本身仍是前沿课题.据此本文概述了结构动力稳定的研究及单层网壳的动力稳定发展,然后基于单层网壳失稳的特点,回顾了现有动力屈曲准则及其局限性,同时指出其发展方向.
With the scientific study and engineering appliance on single-layer reticulated spherical domes,study on static has been satisfactory,but not on dynamics especially dynamic stability.Due to its research lagging behind the appliance,study is urgent and the structure dynamic stability itself is premonitory thesis.In this paper the state of the arts is summarized about dynamic stability of the structure dynamic stability and single-layer reticulated spherical domes.Based on its feature of dynamic buckling,the review on existing criteria of dynamic stability and their limits is presented,and then its orientation is pointed out.
