The load is applied laterally to the column of a frame.http://files.engineering.com/getfile.aspx?folder=cbaf2c70-4da2-4138-b06b-d5bf97a629cf&file=frame.JPG
and this is the attachment of the composite section:

If the section is not composite, then the section would reach such a state shown in the 1st attachment below, right? I (scaled up the upper and lower parts' stress diagrams for the sake of demonstration)
However, in the composite case, the plastic state would be like the second attachment...
The three pieces are not connected though. This is a part of a beam where these pieces are connected at the supports.
When I have certain dimensions, there is no problem, I can find the PNA with several trials by hand.. But I want to write a simple code with which the location of PNA can be...
I want to calculate the plastic neutral axis of the section in the attachment (let's assume the materials are the same). I know that the areas above and below the PNA should be equal.
I want to write an excel sheet which could calculate the PNA with the dimensions entered by user. If it was...
I am back from vacation to work, and it is my first day, and I have to say that I feel much more confident now, and actually happier about my position since I am convinced that I will be learning a lot during this experience! Thanks for all the advices, and talk to you soon!
Trying to have an answer before asking the question and then directing it to the supervisor makes very much sense, this way, I will have brainstormed on the subject, and even though I can't find the answer, I will be prepared and ready to acquire one.
This site has already started to be...
Thank you for each piece of advice, I feel relieved, and undoubtedly I will feel much more confident to ask questions to my mentor, and of course I will benefit this wonderful website as much as possible! Thanks
I am holding a new position which kind of puts me in stress for the following reason:(I am a fresh graduate with a master's degree in structural engineering)
- The company is so small and fresh, and I am the ONLY assistant of the boss, who is a very smart and experienced structral engineer (of...
Hi IJR,
I have a solid prism of 2000x500x500 mm, with the full restraints at the joints, preassumabely the natural periods are very small, around 0,06 sec.
hello,
I am carrying out a non-linear time history analysis. It is a 3D earthquake motion (the real time history acceleration graphs are used in each direction) starting after 1 second of Ramp function where I apply the dead load. And the analysis is based on Ritz vectors.
The problem is that...
