Thrust Forces / Scissor Trusses
Thrust Forces / Scissor Trusses
(OP)
Is it safe to assume that there would be no thrust forces (or the forces would be released) on individual square concrete footings with base pedestals supporting "Scissor Trusses" with pin-pin connections? It is an open roof structure with wind loads on all directions.

It is inaccurate to say there is no thrust, but provided the footing and pedestal are correctly designed to resist said forces, it would be accurate to say they were relieved.

If pin-pin the thrust forces are transferred to the pedestal, to the footing, to the soil. The soil ultimately resists the thrust forces.
