摘要
研究预应力混凝土受纯扭作用时的机理 ,运用变角空间桁架原理 ,考虑混凝土的软化效应 ,并把预应力度引入到计算中 ,提出了新的抗扭强度计算公式。
The principle of prestressed concrete in pure torsion is investigated, by using the space truss theory with variable inclination, considering softening of concrete, and introducing the prestress degree into the calculation, puts forward a new theoretical method for ultimate torsional strength.
