On the basis of comprehensive analyses and studies, now the centrifuge concrete filled thin - walled steel tubular is regarded as one of the ideal substitutes of the traditional concrete poles, and there has been a practical call for the researches on it unfortunately, present evidence is all for the capabilities of the tube under single load but there is hardly any datum relating to those under the combined loads of bending and shearing torsion that many members applied in electric power projects inevitably bear to different extent. this paper intends to improve this situation with the experimental researches and related theoretical analyses done on the subject
在電力工程結構中，由於使用功能要求，許多結構中不同程度地存在著受扭工作狀況，及彎扭、剪扭聯合作用工作狀況，然而迄今為止，國內外對離心鋼管混凝土結構的工作性能的研究大多局限在單一荷載工況情況下，尚未見組合荷載作用的研究，因此，能否深入了解離心鋼管混凝土構件的扭轉和在組合作用下的受力特性，成為影響該結構形式能否進一步推廣應用和發展的關鍵技術問題。 -
