Pushover: Hinges with Piles in Tension

Pushover: Hinges with Piles in Tension

Pushover: Hinges with Piles in Tension

(OP)
I have a pushover model where the piles on one row of my structure will always go into tension when there is a lateral push. When I define my hinge, the pile that's in tension does not follow its defined behavior (all piles in compression do follow their correct hinge properties). I understand that when the pile is in tension, the moment capacity has reduced incredibly. What I've done is defined the hinge for the pile at the tension level I see at my worst load case, so the moment capacity is roughly 1/5th of the compression piles; however, the tension piles still refuse to follow the defined hinge property.

The only way I've found for the tension piles to follow is defined hinge property is by limiting the tension in the pile to 0-kips. Is this safe? Would I be inaccurately modeling this case?

Thanks in advanced,
ceky

RE: Pushover: Hinges with Piles in Tension

Why don't you consider using a PMM hinge, as you would do in case of columns?
