    Description :
    _____________

    The procedure LIMEMECA allors to determine the limit state of
a structure defined by the model MODL1 and the elementary collapse 
mechanismes TAB1 and TAB2 resulting from the operator MESM. The plastic
characteristics of the structure are contained in the field-by element 
MCHML1. The structure is subjected to a varrying load defined by the 
field-by-point CHPO1. However a constant loading (CHPO2) may be also 
considered. 

    FLOT1 is a coefficient (default 1.) which should be increased if 
the optimization is not complete (the logical LOG1 is then equal to 
FAUX). The limit state is defined by the loading coefficient FLOT2, 
the collapse displacement mechanism CHPO3 and the plastic state MCHML2.

    Note :
    ______

    The field MCHML1 is constant by element and given at the nodes
('NOEUD'). It should contain the following components: 'MZ1+' and 'MZ1-'
(positive and negative plastic moment at the 1rst end of the element),
'MZ2+' and 'MZ2-' (positive and negative plastic moment at the 2nd end
of the element), and, eventually, 'F2+ ' et 'F2- ' (traction and 
compression plastic forces in the element).
