yield lines

EK97

The area bounded by the yield lines and supports are called a panel. The significance of the assumption that panels are plane surfaces is that it defines the geometrical relationships […]

EK89

It is assumed that each of the panels formed by the supports and yield lines is a flat plate. The bending deformation within the panels is ignored because the overall […]

EK88

Have a rectangular slab simply supported along each edge, carrying a uniformly distributed load throughout. The slab is assumed to be of constant depth and reinforced in each direction parallel […]

EK79

If we assume that the uniformly distributed load is that which causes a full pattern of yield lines to be produced, i.e. a collapse mechanism, we have an ultimate load […]
