    HILTI Profis Anchor software - design resistance of anchors

    Ok. It's explained on page 43 of "Hilti fastening technology manual".

    HILTI Profis Anchor software - design resistance of anchors

    Hello! I did just a trial calculation in Hilti Profis Anchor software. I used only one anchor HST-M10 and loaded it with both max. resistance tensile NRd = 6 kN and shear VRd = 18.8 kN load (values are for cracked concrete). See screenshot. Utilization is: Tension: 100% Shear: 100% -> both...

    Load set options / Solver parameters _ in Nonlinear Static Analysis

    Can somebody explain me what the numbers marked red in the attached picture mean. And give me some example. I´m not sure if I get it right. First, for solver parameters. There are 100 steps with 0,02 time increment. So those two numbers multiplied give us 2. Does 2 represent the total applied...

    BAR/BEAM element in Advanced Nonlinear Analysis

    Hi, Blas! Thanks for replying. The contact has been set exactly the same way as in the previous simple model that we discussed before. I will attach the new model here. Regards, Edhttp://uploading.com/files/a24d44b6/edinov_spoj_03.MOD/

    BAR/BEAM element in Advanced Nonlinear Analysis

    Hi! Can somebody, please, explain why the top bolt is moving out of the hole? That´s happening to two other bolts on the other side of the part. The simulation runs without errors (but stresses in all parts are negligible so I guess there´s some problem in analysis). Bolts have following...

    BAR/BEAM element in Advanced Nonlinear Analysis

    UPDATE: I just found in Advanced Nonlinear Theory and Modeling Guide that: ´´Both small and large displacement formulations can be used for the bolt’s beam elements. Any cross-section available for the beam element can be used, but only the isotropic elastic material model can be used.´´ I...

    BAR/BEAM element in Advanced Nonlinear Analysis

    Hi! I changed my model´s property and material. Analysis still won´t run if I use Nonlinear Elasto-Plastic material. Attached is the model file. Bolt shank material is ID 2 (Nonlinear Elasto-Plastic) and property is ID 4 (Nastran ROD, PBEAML/PBARL). The results can be obtained from linear...

    BAR/BEAM element in Advanced Nonlinear Analysis

    Thanks a lot, BlasMolero. I ve never used this NASTRAN cross section before. I guess that s what I was missing. I think it should work now. I m on holidays now, but will try that next week and let you know if it works. Regards, Ed

    BAR/BEAM element in Advanced Nonlinear Analysis

    Yes, I found that in the Advanced Nonlinear manual, but how to set that up? I made a BEAM element property with CIRCULAR BAR cross-section and it doesn't work. And how to set up the bilinear plastic material?

    BAR/BEAM element in Advanced Nonlinear Analysis

    Thanks, I know that, but it should be possible to use non-linear plastic material for BEAM (not BAR - maybe in this model it's BAR element, but it doens+t work with BEAM either) element in Advanced Nonlinear Analysis. I have to do that because I'm modeling 10.9 bolt material. This here is just a...

    BAR/BEAM element in Advanced Nonlinear Analysis

    thanks for reply, but that's not an issue. i am aware of everything. the bolt shank will be just axially loaded and i want to avoid contact between shank and the hole in plates. i just need to run analysis which can handle both contact and preloaded bolt.

    BAR/BEAM element in Advanced Nonlinear Analysis

    Hi! I´m trying to model a preloaded bolt which connects two metal plates. The plates and bolt head/nut are 3d SOLID and bolt shank is a preloaded BAR/BEAM element which is conectid with spider curves to bolt head/nut. Since there´s a contact between elements I have to use Advanced Nonlinear...
