It is a free standing frame to support roller door. What would be the basic car impact load?
Is it F=0.5*M*V^2/(deflection of column + deformation of vehicle), how much speed should I take?
What if there are no walls, if we consider it as a free standing frame with roller door. Can I consider it as free standing wall then? Yeah, it sounds abnormal to consider vehicular impact load, but what will be the appropriate load according to Australian Standard.
I have to design a structural frame for garade door, made of shs column and pfc channel section. How do I calulate the wind load on the frame? Can i considered it as free standing wall and calulate the load? Is it necessary to calculate vehicular impact load on the column, it is a residential...
I used contact for both rebar. The answer seems incorrect, what might be the reason? Shouldn't there be more stress at the middle wire where the load is applied ?
I was trying to test reinforced wire mesh on point load . I modelled the rebar as wire element and assigned it as beam section . I applied tie constraint on horizontal and vertical rebars. The load is only transferred to the applied wire and it is not transferred to adjacent wire. what is the...
When the plate element slenderness is less than yield limit λey, it is non-compact. Why are not we checking λe<λep plastic limit? If λe<λey, while it is not slender, but it still can be non-compact section, whereas if λe<λep, the section will be fully compact
If the section is compact, it won't...
"At a composite beam cross-section, the web(s) of the steel beam will normally be subject to
combined vertical shear and bending. The design moment capacity of such a cross-section is
assumed to be reduced once the shear stresses in the steel web(s) are sufficiently large. Shear
reduces the...
Thank you so much for all the replies. That's the file. I wanted to ask you one more thing; Do we need to create a separate static step for pressure and a dynamic step for impact, or we can create a dynamic step for both pressure and impact?
In my case I kept the time period as 0.05 and space between the target surface and the impact object is 100mm and velocity of the object is 22m/s. 0.05 time period is enough for impact. I changed my time period to 0.1 or 0.01 which is also enough for the impact but why do i get different stress...
I am new to abaqus so I am having a lot of difficulties. It shows element distortion error when i try to make the mesh size small at impact location. I did managed to make my mesh size resonably small for the solution. But, there is variation in my result if i change my time duration why does...
Thank you for the response. I have tried using shell but again I received an error message. I have attached my file. In the error it says"Excessive rotation of nodes in node set...
I was trying to test a hemisphere of 2 layer each of 50mm thickness made of different material for impact load and pressure. I received the above error after submitting the job. I modelled the shell(hemisphere) as solid 3d deformable. I think the error is due to meshing, can anybody help me with...
I was modeling beam and slab mat footing in SAFE i think it modeled beam and slab as straight T and L beam as shown below
how can i model it as inverted T beam and slab footing
yes they are cast in place stairs so I was inclined to include them in my model
I removed the stairs but still there is torsion in second mode

Regarding steel stairs with pinned connections , I haven't come across one if you have a picture can u post one
And what if i provide corbels...
