Mansory muti story

[mjoflor]

Hi i have a multi story building ( 3 levels) in mansory walls, any documentation, example or tutorial , can help me, thanks

Neither masonry parameters (orthotropic material properties) nor their design are not supported in the current version of Robot and you have to decide what kind of the simplified approach you would like to use. You can define e.g. the orthotropic thickness reducing the stiffness in the horizontal direction, apply linear releases at the vertical edges so that  the horizontal tension force is not transferred, replacing masonry walls with loads.

thanks, any example, or tutorial or documentation can help me, ???????

How can i get this:"apply linear releases at the vertical edges so that the horizontal tension force is not transferred, "?????

 What type of masonry buildings are you refering to? Are you talking about reinforced type (with hollow blocks e.t.c) or about stone masonry buildings?

  Both are intersting (and quite difficult to figure out) issues.. One of the main objective is to take into account the out of plane responce of masonry walls too. I suppose Artur is talking about the first case ("orthotropic naterials"), it will be interesting to see some kind of example about what he proposes.

See the attached picture.

Thanks for all, but I have the next question it´s valid for cortain wall, or only for shell element, i mean the linear releases

[Artur.Kosakowski · Accepted solution]

As the curtain wall panel calculation model means that there is no mesh you cannot apply linear releases. On the other hand such panel (curtain wall) is just intended for load transfer with no structural role in a model.

HI

On the other hand such panel (curtain wall) is just intended for load transfer with no structural role in a model.

The curtain wall facade does not carry any dead load weight from the building other than its own dead load weight.The wall transfers horizontal wind loads that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, sway induced by wind and seismic forces acting on the building, and its own dead load weight forces.

Hi Artur

Please find the attached file. Can you explain the parameters for nonreinforced masonry wall in Orthotropic==> Constant thickness reduced stiffness dialogue box?

[HoshangMustafa]

Sorry

Please find the attached file.

Hi

I guess f is the membrane stiffness and k is the flexural stiffness, but I couldn't find in the help menu these parameters so I wrote this post to be sure of it. What about v parameter?

Hi Artur

Thanx u very much. Why aren't these parameters explained in Help menu?
