AI Thread Summary

To calculate the moment of inertia for a thick-walled T profile, the center of gravity has already been determined. The next step involves applying the equation I_G = ∫ r² dm, where r is the distance from the axis of rotation and dm represents the differential mass element. It's essential to define dm in the context of the T profile's geometry. Understanding the distribution of mass relative to the axis will facilitate the calculation. Properly applying these principles will lead to an accurate moment of inertia for the T profile.

I_G=\int r^2 dm. You should find what dm is worth in your case.

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
