infill wall model

Post by jackjo »

Hi everybody
I modeled a infill wall by considering the presented model by Dr. Mosalam and Dr.Gunay that exists in OpenSees page, My model is 2D and assigned it to a 2D one story frame (one bay) and units are SI. When I run this model, I encountered a warning as follows:

WARNING invalid A
Elastic section: 12
expected floating-point number but got "<107994050.4424561.4424*4.9453741294264075>/<1220372038"
while executing
"section Elastic $sectionpin $Em $AreainfM 1e-7 "

By attention to above warning, this error display because of being a problem in making elastic section for pin connection. This part (elastic section for pin connection) stated in opensees page presented by Dr Mosalam and Dr Gunay.
Please guide me to solve this warning.
Thanks so much

Opensees is telling you : I want a floating-point number but you give me this, whatever it is " <107994050.4424561.4424*4.9453741294264075>/<1220372038 ".
Make sure you enter your numbers in the following way :
To enter 1, enter 1.0
To evaluate a expression (such a multiplication) use the command [expr ] like : [expr 1.0+1.0] (the answer will be 2.0).
To get a non floating number (like when you define a node tag number) use the command int() inside the [expr] command :
[expr int(1.0+1.0)] will yield 2, not 2.0.

Hope it helps.
