Hello,
I am a licensed structural engineer specializing in steel and reinforced concrete, but my question is related to wood framing.
I have a friend building a residential home (CMU walls and wood-framed floors) who asked my opinion on placing a home gym on the second floor. I don't plan on...
Hello,
I need some help determining the stress in a "stiffening beam" at service level loads. At the service level moment, the concrete is uncracked. I'm not exactly sure why, but the fact that the concrete is uncracked has made this analysis extremely confusing to me, so I wanted to get a...
Hello,
I am trying to determine if it's possible to use an effective length factor less than 1.0 for a double angle bolted to a 1/4" gusset plate. The gusset plate is welded on both sides to a column and a beam. I feel that the length of the member should be measured from center of bolts to...
Hello,
I'm trying to convert engineering stress-strain to true stress-strain using an Abaqus model and an iterative approach. I understand that up to the yield point engineering and true stress-strain is identical, up to the necking point they are similar and can be related by:
σT=σ*(1+ε) (1)...
Is there any way to show a plot of nodal forces (with force arrows) in Abaqus, similar to what is shown in FEMAP/NASTRAN below? So far I con only figure out how to show resultant forces on a cut.

Does anybody by chance know how equation 9-29 from the 15th edition manual was derived? I’m trying to find the “source” research that we used to define this equation and haven’t had any luck.
The equation defines the punching shear strength of HSS-HSS connections. I have a connection that...
I am in the market for a new home and, being a structural engineer, I’ve considered taking part in the design process of a custom home. My specialty is steel, so naturally I’m interested in designing/building a steel home, if the price is right.
I’m not planning on starting this effort in...
Hello:
I'm doing some initial market research on the design of cold storage facilities. Does anyone here have experience designing these facilities and can give a quick summary of the special considerations?
Are there unique building codes that are used specifically for cold storage...
Is there a way to track the strain history of all nodes on a line and report when any node/elements plastic strain exceeds the limit strain? I would like to track strain around a weld line and use 5% strain as a limiting value.

Hello:
I'm continuing to try to automate my processes in Abaqus.
As has been the theme in my last couple posts I have a manual task that I need to repeat over and over to complete my research and I'm searching for way to make it more automated.
I am loading the top of an HSS using a single...
I'm trying to line up multiple analyses in Abaqus to run one after another using a Python macro.
My desired workflow is to start with CAE open and run the macro while viewing the first model in the set. I've written the below code to create an analysis for the active model, run the analysis...
Hello,
For my research I have to create the same XY plot with different data a painful number of times. I am trying to use an Abaqus macro to make my life easier, which seems to work great until I try to use it on a file that I did not create the macro in. I see when opening the .rpy file in a...

What is a real example of a column that is fixed at it's base and at it's top is free to translate, but fixed against rotation? Would a sign post be considered in this category, or would it be considered fixed at base and free to rotate and translate at the top?

I have a error that is driving me mad. I have created a model of an HSS connection using shell mesh. For some reason where two HSS meet eachother I am getting an error that
1) Mesh is distorted
2) There are zero area elements
No matter how much I refine the mesh the problem doesn't go away...
Studying for the PE exam and notice I miss a lot of details from ASCE on seismic and snow, since I don't live in an area where I have to design for the respective effects. Also noticed that the PE questions like to ask about simplified wind methods, which I know little about.
I came across the...
Does Abaqus have any capability to perform dynamic motion analysis similar to ADAMS?

Has anyone here recently taken the structural PE and could recommend practice tests/books.
I have:
PEprepared Practice Tests (Breadth & Depth)
NCEES Practice Tests (Breadth & Depth)
EET course binders
I'm looking for some more practice material if anyone has any recommendations, or even...
Does anybody know how to numerically integrate the following formula in Matlab?

What's the best way to represent an edge weld for two shell structures modeled at midplane? I want to extract weld force to design the welds by hand.

Is there a way to "project" 2d loads onto a 3d surface in Abaqus? I have CFD loads in a spreadsheet that are provided in one plane only with a single pressure value. I'd like Abaqus to interpolate and apply loads onto a 3D surface considering the plan coordinates of the model nodes only.
“The...
