This paper describes the experiments on three reinforced concrete portal frames under variable repeated loading. The results obtained are almost consistent with the theoretical shakedown values. Thus it can be concluded that the shakedown theorem is also applicable to reinforced concrete structures.This paper points out that with the equal magnitude of loading the variable repeated loading is more disadvantageous than a simply applied load to a structure. In the design of a structure there is a region where...

This paper describes the experiments on three reinforced concrete portal frames under variable repeated loading. The results obtained are almost consistent with the theoretical shakedown values. Thus it can be concluded that the shakedown theorem is also applicable to reinforced concrete structures.This paper points out that with the equal magnitude of loading the variable repeated loading is more disadvantageous than a simply applied load to a structure. In the design of a structure there is a region where the structure may be safe under simply applied load but doesn't shakedown for variable repeated loading. So it is necessary to give a new meaning to the safety of a structure loaded by a variable repeated loading.

This paper inferred the geometry firm degree formation which influence clasticity con-struction,in depth alternately each other,transport load acting. From general highly theoryof impetus instability,we not only consider the affection of shear effect when firm degreeformation is formed,but also consider it when geometry firm degree formation is listed.Asaresult,the construction about shear and infleet firm degree which are almost indistin-guishable, has an accurate instability edge,especially shear alter,the result accuracy ofwhich greatly increased. Through practical calculation, the effect,which acts on geometryfirm degree formation by shear effect and the difference ignoring this kind of influences,provided the relevant impetus instability region.The calculating result is as same as the the-oretical analysis.For those engineering practical constructions which shear firm degree aresmall,the infuence which acts on geometry firm egree by shear effect should not be ignored.

从一般的高等动力失稳理论出发,推导了影响弹性结构在纵向交变荷载作用下的几何刚度阵。不仅在形成刚度阵时考虑了剪切效应的影响,而且在列出几何刚度阵时就已经考虑了这一效应,使得那种剪切和弯曲刚度相差无几的结构有了确切的失稳边界,尤其是那种以剪切变形为主的梁,使其结果的精确度大大提高。通过实际计算,分别考虑了剪切效应对几何刚度阵的影响与忽视这种影响的差别,给出了相应的动力失稳区域,计算结果与理论分析是一致的。对于那些剪切刚度比较小的工程实际结构,不应忽略剪切效应对几何刚度阵的影响。
