IN-PLANE STABILITY OF DEEP CIRCULAR ARCH UNDER UNIFORM RADIAL PRESSURE

The in-plane stability of a deep circular arch under uniform radial pressure is studied by using the small deformation theory solutions and the numerical solutions of the finite element software ANSYS. The application examples indicate that the stability of the arch under radial pressure is superior to that under hydrostatic pressure with small central angle and is inferior to that with a large central angle.
