modelling of infilled wall with truss element

[Sangwook]

Hello, I selected truss element to present the infilled wall.
Thus, I have to insert the information about the $matTag in truss element using hysteretic material.

However, in tension part, I couldn't make up my mind.
Is it right to insert a zero-value? because typically, infilled wall is vulnerable to tension.

Thank you.

Hashemi and Mosalam (2006) used truss element and Concrete01 material to model an infill wall as a diagonal strut and obtained reasonable match with the shake table results. In that sense, it can be considered as a simple enough and reliable approach. Concrete01 has 0 tension capacity.

hello, fmk. Thanks to your reply.
I could refer to that research due to you.

However, as you can see the manual, concrete01 just permits the concrete compressive strength and crushing strength.
If I want to input the yielding point, ultimate point and crushing point into the concrete01 except for crack point, concrete01 isn't proper?
Then, in this case, should I use the hysteretic material and insert a zero-value in tension field?

Thank you!

you can.

Hello ,
Now I am trying to use Concrete 01 material to define the truss element. Eventhough I assigned the concrete o1 as a struct element, the strength of infilled masonry wall is still as the same of the bare frame result? Why? Can someone give me an advice?
