In order to investigate buckling mode, buckling load and failure mode of structure, shear experiments were conducted for stiffened thin-walled composite plate. Finite element method was also used to analyze the buckling behavior of that composite structure. Analysis results reveal buckling mode and buckling loading of finite element analysis are accordable with experimental results.

The buckling failure measured includes: the relationship between controlled cyclic curvature and ovalization at buckling, and the relationship between the controlled cyclic curvature and the number of cycles to produce buckling.

力學行為包含有：彎矩－曲度的關系及橢圓化－曲度的關系夜夜草AV，而皺曲損壞包含有：控制循環(huán)曲度－到達皺曲橢圓化的關系及控制循環(huán)曲度－循環(huán)至皺曲圈數的關系。

Elastic buckling and inelastic buckling of arch with and without out-of-plane brace under full span distributed load and concentrated load are investigated The effects of the brace to the out-of-plane buckling load of arch are studied.

對拱結構在全跨均布荷載和跨中集中荷載作用下的平面外屈曲性能進行了研究囯片产av无码毛片一级，其中考慮了屈曲前變形路徑的影響和面外支撐情況一级a性色生活片厕所偷拍，為工程設計提供了有參考價值的建議。

Aiming at the problem of buckling stability capability of box section hoist boom of wheel crane, a complete section of hoist boom is taken as analysis object and buckling instability of the webs is analyzed and researched with the booms of different sectional shapes by applying finite element analysis method. Compared with crane design code (GB3811-83), one piece of plate is taken to calculate buckling stability, the method is easier and more accurate and calculation and analysis of complicated sectional shapes are easy to conduct.
