For the traditional calculation model of wind column, the top is fixedhinge. It means that the longitudinal stiffness of workshop is infinite.
传统的抗风柱计算模型为上端不动铰，即认为厂房纵向刚度为无穷大。

The design of the shell with two bearings which were fixedhinge bearing and flexible hinge bearing was introduced. The process of the stability analysis and the eigenvalue analysis were given.
为了保证设计安全，分析时采用弹性支座和固定铰支座形式，分别进行了特征值以及整体稳定分析。
