Re: railing design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
How are the ends of the rail connected?  In considering only the vertical it
sounds like the ends are not connected.  If the ends are connected, I would
ignore the verticals and treat the rail as a beam and compute deflection
from load at center.  If they are not then the load at one end would be
critical and should be analysed on the bending strength of the first
vertical.
                                                                        Greg
