摘要
本文回顾了国内外混凝土结构扭转理论的历史发展,尤其是最近十几年来的进展。文中就有代表性的斜弯理论和空间桁架理论进行了述评。并按照结构构件受纯扭、弯扭及弯剪扭联合作用等加载方式,对于素混凝土、钢筋混凝土和预应力混凝土结构扭转的计算方法进行了归纳。最后对我国开展混凝土结构扭转理论的研究提出了建议。
The paper reviews historical development of torsion theory research for concrete structures both at home and abroad, especially, its development in the last ten years.Skew bending theory and space truss theory are discussed briefly in the paper. The paper summarizes the torsional calculating methods for plain, reinforced and prestressed concrete structures according to different loadings: (1) pure torsion; (2) torsion combined with bending; (3) torsion combined with bending and shear.Finally, some proposals are made concerning the further researches on torsion theories for concrete structure in our country.
