This work investigates the compressive load carrying capability of experimentally tested reinforced steel panels
with a large lightening opening. A series of experiments have been carried out on reinforced panels with circular
and elongated circular opening of different sizes. The effect of different opening shapes, different opening sizes
as well as different initial imperfection shapes and amplitudes, on the loading carrying capacity are studied. The
resultant collapse modes are presented and both initial and post-collapse shapes are analysed and the sequential
occurrence of the post-collapse deformation shapes have been analysed. The experimental results of forcevertical/
lateral displacements relationships, strain energy density and stress-strain relationships are presented
and analysed. Finally, the experimental results have been compared with other experimental ones for unstiffened
plates with elongated circular opening subjected to uniaxial compressive load.
