Moment of Inertia of a typical trapezoidal-type corrugated sheets.
(OP)
HI,
Could you anybody support in finding out Moment of Inertia and Moment of Resistance for a Sheet with following characteristics.
attached is a figure with key generic dimensions.
Any help/pointers/formulas would be greatly appreciated.
Thanks,
DG

2 - you can make a drawing with autocad and find it easily
RE: Moment of Inertia of a typical trapezoidal-type corrugated sheets.
without seeing your sketch, change the sloping sides of the trapezium with vertical sides, so now the section is a bunch of rectangles, horizontal and vertical.
make sure not to double count any areas. the vertical rectangle can be placed at the mid-point of the sloping side, if you have to worry about the other axis.
clear as mud ?

For gross properties only, AutoCAD is a good suggestion. If you need to repeat this for many shapes and variations, a software intended for this would serve better.

Your corrugated sheet is equivalent to a channel with vertical and somewhat thicker sides. That increase thickness can be calculated.

By any chance is it sheet piling?
