Hello everyone. Sorry for the late respond. Thank you for all the explanation and discussion in these past 2 days from phamENG, KootK, Dylan0022, driftLimiter, Celt83, and JLNJ.
@phamENG
Yes I understand and I will look into that too, thank you for your explanation.
@KootK
The center of mass...
@phamENG
In this case (2 types of wall with different stiffness), I try to know what the program does that resulted this problem. I think if I try hand calculation the result will be normal (bottom story will always be greater than the top story).
@KootK
Thank you for your response and...
I have an example building consist of 7-story with 3 types of shear wall (P2, P3, and P4). I apply the same amount of lateral force each floor (1000 kN) using ETABS with rigid diaphragm floor. The slab/floor is defined as shell with automatic mesh. The lateral force ordinate is in the center of...
Hello.
An update on my design, I am thinking of following what AISC 360 said in Chapter I3 option (c) about Encased Composite Members, that is, by using plastic stress distribution or the strain compatibility with shear studs provided on the steel beam.
I am currently making a strain diagram...
Hi all. I am very sorry for the late reply.
Thank you WARose, KootK, and BridgeSmith for all your help and thank you for all the discussion on this thread.
Thank you BridgeSmith for your thoughts on this thread.
If i want to use the method that you suggested (designing WF beam alone, concrete beam alone, and then add them to get the moment capacity). Will it be considered as a fully composite beam with full composite action? And about the...
Thank you KootK for your thoughts on this thread. They are very helpful.
Yes, for the inertia and stiffness it is better to follow #2 path.
But what confuses me is the strain distribution because now concrete got involved (the ratio of reinforcement limit and the concrete crushing limit at...
Thank you kostast88.
I am thinking about using self compacting ooncrete for this beam. Maybe it can help with the bottom flange blocking the concrete problem.
If I treat this as a steel beam only, is it safe for the concrete? Because the owner insists that they want to cover the steel beam...
Hello. I want to ask about the theory of encased steel beam in concrete. I have an I wide flange steel (dimension 588x300x12x20) encased in a concrete beam (600x950mm). I have a screenshot of the section below.
If I want calculate the moment capacity:
1. Do I have to consider the...
