critical buckling coefficient of thin-walled steel plate in biaxial stress is obtained by interaction analysis of steel tube and concrete.
通过对方钢管与混凝土相互作用的分析,得出薄壁钢板在双向应力下的临界屈曲系数。
using buckling deformation function that satisfies the restraint boundary condition of the plate, an explicit solution of buckling coefficient is obtained.
