For finding frequency of pole you can use any FEM software and use eigen value solution.
If you want to do this by hand procedure is as follow :-
Here I have considered that there is mass lumped at the tip of the pole.
1) Calculate the deflection of pole with horizontal unit force at the tip of...
I agree with paddingtongreen but as a safety check for punching at the face of ladder leg......... If it is safe there no need of worry.......
Others can share there opinion
Dear Kapil,
The choice of method is a judgement of structural engineer. If you ask me I will prefer seismic coefficient. If the structure is complex then only I will go for response spectrum method.
The preference for seismic coefficient method is due to it's simplicity to use. Also combining...
If you want to resist moment with single bolt then it is not possible .............. Theorotically single bolt means pin connection and it will not resist moment.
If you want to design group of bolts for bi axial design then you have to go by trial and error method to find neutral axis and do...

We cannot compare beam elements with plates / shell elements in FEM software. The shape functions for beam element in FEM software are exact and for shell / plate there is approximation. If we apply concentrated load at single point then there is condition of singularity and you can...

I agree with you
the practice thich we follow is just neglect plates which fall inside pedestal or pile crosssection this care we take while designing.
This can be safely justified because at pedesatal ans pile cap junction the c/s area of plate is very high. One have to consider...
If you are using finite element software to find the mass distribution then please ensure that supports which you have given are fixed one......... if it is pinned one then there are chances of moment distribution and changes in reaction.
