Cladding option

[giyotd]

I am trying to use the cladding option but there are some points that i didnt understand in the help :

What is the difference between these 3 types of load distribution (if i have uniform load on my floor which type should I use)

The list field displays 3 available types of load distribution based on the load direction:

            
• Two-way - isotropic
• One-way X - anisotropic: parallel to the local x axis of a panel
• One-way Y - anisotropic: parallel to the local y axis of a panel and perpendicular to the local x axis of a panel.

2) i couldnt ubderstand what's the problem of the truss with cladding (" Use the Do not take truss bar into account option by selecting objects on which loads from               a cladding are distributed.")

Note The trapezoidal and triangular method is used to distribute loads for all cladding types. Because distribution methods are limited to this method, you cannot define               new types of load distribution. Use the Do not take truss bar into account option by selecting objects on which loads from               a cladding are distributed.

hey Rafal,

I have a one way deck slab in the X direction,

so what i have done is using clading with the load distribution in the x direction.

but after checking the results i figured out that some trusses have a very low axial forces comparing to others (like bar 268,332,488,479) in my robot file below.

No you did not

Even if you set One-Way-X please check local CS of cladding.

Almost all of beams are not parallel to local X of cladding so they will be loaded

Can you give me a hint what to do

Maybe you want this:

Rafal ,

I have done what you requested, but my question is why on certain truss bars like (268,332) the axial force is very low comparing to others

Thanks again for your help

Your model is inaccurate

1 delete all meshes

2 correct nodes coordinates as shown below:

Nodes  105 106 117 302 306 331 437 438  should have  Y=351,38010

Nodes 19 20 56 103 104 116 519to525 should have    Y= 338,45950

Nodes 23 24 58 101 102 115 should have  Y=311,61050

Nodes  27 28 59 97 98 113 257 263 284 289 298 305 318 452to462   should have Y= 299,69429

Nodes  29 30 33 34 60 61 242 245 247 251 256 262 269 288 293 439to451 should have  Y=290,37611

Nodes 331 437 438  should have  X =197,37518     Y=351,38009

Node 60 coordinates : X=187,99256         Y=290,37611       Z=21,87500

Add nodes on crossing points as indicated on screen shot below

Thanks Rafal for your help

 Hey Rafal,

I am facing the same problem on some beams number(231,213,209,204,199,337,225,345,16,19,189) i am not having bending moment (My) on these beams

I have tried the  fix the nodes as you have mentioned before but it didnt work,

i would really appreciate if you can help me also this time

Update your Robot with Sp4

[giyotd]

is it better to update it to this version or 2014,

since my company didnt buy yet 2015 version

regards,

George

[Rafal.Gaweda]

is it better to update it to this version or 2014,

Your choice but it is always better to use the newer possible version.

If you will use 2014 please update it with the latest SP also.
