horizontal deflection calculation of building frame
horizontal deflection calculation of building frame
(OP)
for a typical one bay one story building frame. There is a equation to calculate the lateral deflection (like story drift) of the frame. Vh^3/(12EIc)+Vh^2*L/(12EIg). In this equation, I can understand the first item. But could somebody explain the second item to me. I konw the second must come from the rotation of the joint and has something to do with the beam stiffness. Is this formula from the stiffness marix (6x6) of a beam member?
Thx.
Thx.
