I understand in the case of a beam, we are talking about LTB and hence the deflected shape doesnt matter. Similarly can't we assume its brace at the connection for flexure in the inplane direction?
Kootk, I have a related question in a baroader sense. A stupid question.
You say that unbraced length is from the points where the double derivate of the deformed shape changes and hence thats not at the point where the brace connection happens. Like we see in the picture attached, when we...
Kootk, Only one correction, I dont have a knee brace per se since the brace connects to the column at lower than the mid-height (I agree that the markup attached is a little misleading). Your conservative analysis would work when its somewhat at the top of the column. How would your answer...
FIle attached.
I did go through Appendix 6. Assume the brace is strong enough and has enough stiffness. What is not sitting with me right is that the element this is loading the column is also bracing...
I'm designing a brace frame and I have a question regarding fixity. (Geometry file attached)
Its a chevron bracing system. It has grvaity loading and inplane loading. I want to ask if we can assume that the column is braced by the brace at the location where the brace connects to the column...
