Plastic collapse load analysis of undefected pipe bends under the loads of internal pressure and torsion;

Based on Von Mises yield condition, the plastic collapse load equations for the pipe elbows under the loads of internal pressure and torsion, and the loads of internal pressure, bending and torsion are derived.

We present a new method for analyzing the plastic collapse load of undefected pipe elbows under inner pressure based on twin shear unified strength theory,and the unified solutions for plastic collapse load are obtained.

Based on the twin shear unified yield criterion, the plastic limit loads of simply supported circular plate under uniform annular load are given.

The principle is as follows: Find the plastic limit load by the elastic adjustment-QR method; Establish limit state expression in terms of plastic limit load; Find reliability index of structures; Find system reliability by reliability index.

The elastic and plastic limit loads of circular silos are studied.
