Hi,
Assume there is a small pipe and a large pipe. The small pipe is concentrically inside the large pipe but they are not in contact (i.e. gap between the outside of the small pipe and inside of the large pipe). The analysis goes through multiple steps causing each of these pipes to deform...
Hi,
We have been given a large dataset which includes the following data from an analysis done in another software:
- (x,y,z) of a large number of points in space (~1000s)
- For each point, an amplitude (with quite a small increment size) which is the time history of the applied pressure at...
Hi,
I've encountered an odd issue while using bending-only shell elements in explicit. Due to the requirements of a project, I have to use bending-only shells, however, they appear to provide reasonable results only if they are used in an implicit analysis. As shown below, using them in...
Hi all,
We’re working on a large model with a complex contact condition; however, we’re getting some unreasonable results. We’ve pinned down the problem to a strange issue with the explicit solver. I’ve made a small model (*.inp files attached; figure shown below) which clearly shows the...
Hi,
I've been recently exploring ETABS slab design features (only available in the Ultimate edition). Both Slab Design (for strength checks), and Cracked Floor Analysis (for service checks including cracked and long-term deflections) are rather good in my opinion if you know what you're doing...
Hi all!
I have a simple question. Could anybody explain what exactly is a spine model in programs like CSI Bridge?? I know that these elements, model the whole superstructure as a single frame element; But how does it calculate mechanical properties of the section - For example torsional...
Hi guys!
I have a question that has confused me these days. In SAP2000 when importing steel sections from *.PRO lists, there are several AISC lists like: AISC-ASD9, AISC-LRFD3, AISC-3, AISC, AISC-13, AISC-13M , etc.
I kind of figured some of them out. So I know that AISC-ASD-9 list is from 1989...
Dear all!
one of my colleagues has the following question:
Does anybody know the UNIT of the "k" parameter in the "Nonlinear Muskingum Model"?
Any help would be really appreciated
Hi! I am really new to SAP2000 API and I am trying to use MATLAB to interact with SAP. I'm getting help from SAP2000 API documentation. I have built a model using SAP and saved it. Then I used the following code to open and analyze it using MATLAB interface. The problem is, I can't get any...
Hi,
AISC-360 part C.13 and many other design codes indicate that, for staggered holes, the "Cochrane Equation" (the famous s^2/4g formula) must be used for determining "Net Area" of the tension member. I have used this equation several times in design, but I can't find any references that...
I'm trying to design an End-Plate connection. I have to use pre-tensioned bolts because of regulations. so my question is where can i find a design procedure for this connection.
it's worth mentioning again that i want to use pre-tensioned and not normal bolts.
I'm designing a SMF 12 story steel frame building. according to AISC, in SMF, both flanges of the beams must be laterally braced. can anyone PLZ send a detail about this lateral support.
I would appreciate any elp

I am trying to use a cruciform column for a 12 story SMF structure. all of the flanges and webs of the section are built of plates and no I-beams are used. I have uploaded a picture of the section.
my problem is: How to calculate the fillet weld's dimension for welding...
