PROGRESS IN TORSION THEORY RESEARCH FOR CONCRETE STRUCTURES

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...
