Shear lag in tension members!!
Shear lag in tension members!!
(OP)
I want a simple way to understand shear lag in tension members I don't know what the relationship between X' and the length of connection

RE: Shear lag in tension members!!
1) Commentary section D3 of the AISC steel manual and:
2) Google "Whitmore section".
The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
RE: Shear lag in tension members!!
are you talking about a specific code ? (what the heck is X' ??)
i found this on the AISC site ...
"5.3.4. What is shear lag and when must it be considered?
Shear lag describes behavior at an end connection of a tension member where some but not all of the cross-sectional elements are connected; the area that is effective in resisting tension may be less than the full calculated net area. Procedures for treatment of shear lag and determination of the effective net area in bolted and welded connections are provided in the 2005 AISC Specification Section D3.3. Alternatively, shear lag concerns can be addressed by selecting a connection length that mobilizes the entire load-transmitting capability."

RE: Shear lag in tension members!!
(U=1-X'/L)
where, U=shear lag coefficient
X'= connection eccentricity
l = connection length
I don't know from where this equation come from?
