Abstract: Torsional resistance of a single prestressing tendon was derived on the basis of the theorem of virtual work to control the torsional rotation by nonequal prestressing forces on both sides of the webs of a flexural member. ...

Abstract: Anisotropy due to directional loading in concrete has been observed not only in the postpeak range, but also before the peak strength is reached. The traditional isotropic description of a self-similar loading surface ...

Abstract: Torsional resistance of a single prestressing tendon was derived on the basis of the theorem of virtual work to control the torsional rotation by nonequal prestressing forces on both sides of the webs of a flexural member. ...

Abstract: The nonlinear behavior of concrete is complex and is governed by a variety of parameters. As a result, there exist a number of constitutive models that try to predict concrete behavior beyond the linear elastic limit. A ...

Abstract: When a prestressed double-T beam is subjected to torsion, a pair of prestressing tendons resists torsional rotation because of the restoring action of the displaced prestressing tendons. A comprehensive formulation to ...
