PLASTIC ANALYSIS OF SLABS
PLASTIC ANALYSIS OF SLABS
SLAB: Structural element contained in a plane (the third
dimension is much smaller than the other two).
The load direction is perpendicular to the structure plane

PLASTIC ANALYSIS OF SLABS
YIELD LINES: líneas de rotura (plástica)
YIELD LINES = ROTATION LINE
YIELD LINES METHOD
7. STRUCTURAL ANALYSIS II
PLASTIC ANALYSIS OF SLABS
VERY IMPORTANT: DRAW THE CROSS SECTION!!!!
Based in the VIRTUAL WORK PRINCIPLE: Wext = Wint
8. STRUCTURAL ANALYSIS II
PLASTIC ANALYSIS OF SLABS
YIELD LINES: BISECTRICES
YIELD LINES CAN BE POSSITIVE OR NEGATIVE
1.- Yield lines divide the slab into rigid regions which remain plane through the
collapse;
2.- Yield lines are straight;
3.- Axes of rotation generally lie along line of supports and pass over columns;
4.- Yield lines between adjacent rigid regions must pass through the intersection point
of the axes of rotation of those regions;
5.- Yield lines must end at a slab boundary;
6.- Continuous supports repel and a simple support attract yield lines.
