load combination for pipe rack foundation design
load combination for pipe rack foundation design
(OP)
When i study a piperack design example, i found the load combination is 0.5 times friction load added anchor load for the piperack foundation design. Who can tall me why the combination factor 0.5 is considered? As per PIP-STC01015,the load combination is Ds+ Do+ Ff+T +Af and the factor is 1. Is this example wrong?






RE: load combination for pipe rack foundation design
Also, you should identify your terms better. I would presume the following:
Do = operating load of equipment and pipes
Ff = Friction load
T = Thermal load
Af = Anchor load
Though my assumptions could easily be incorrect.

For foundation design, thermal friction csncels or only minimal is considered because they act in oppoaite direction.
You need to refer to your company design guide for piperack if you have one.
