If you really have plane strain, this obviously makes no sense because you canot deform your material in the third direction. However, Abaqus allows to use generalised plane strain elements, where the whole structure deforms in the third direction by the same amount. As far as i know, you can apply a load in the third direction in this case - consult the manual under "generalized plane strain".
