I am a little bit confused of the solution to the biharmonic equation because it seems to me that if I use the Navier solution to the equation I will get the same answer no matter which boundary conditions I choose (simply supported or fixed edges). For example my solution to the boundary...

I did look at the Reinforced Concrete Designers Manual (not sure what publication) but I was unsure whether or not I could consider this a straightforward rectangular culvert due the massive size of the structure. Though sectioning the model into 1m length box culverts may be a fair...
Yes it is the same problem. The reason I wanted to use this method is because I need to know the internal forces throughout the flat slab. The solution to the biharmonic equation would give me deflection and from that I would be able to determine the internal moments.
I actually found this...
Hello,
I am trying to determine the Internal moments, torques and twisting moments in a flat plate with fixed edges. I have taken a look at the biharmonic equation method and I am able to solve when the edges are simply supported but I am having trouble solving this equation when the edges are...
Hello again,
I am trying to find areas of maximum internal bending moments in the walls of a concrete structure. The shape of the structure is a rectangular box and is quite massive (about 5m x 7m x 30m). The structure is underground and will experience varying pressures along the side walls. I...
