To reduce computational effort of finite element fe calculations a corrugated sheet is replaced with an orthotropic plate. I iint a y 2 da where a is the area of the shape and y the distance of any point inside area a from a given axis of rotation. Also a higher order shear plate theory was considered expressions for the moment of inertia per unit length of single sheets with arc and tangent type corrugation have been given by blodgett 9 and wolford 10. Mm4 mm see tables 2 35 il pressure from impact load lbf ft2 kpa k soil stiffness factor 0 22 for good side fill material compacted to 90 of standard den sity based on test method d698 l 1 l 2 l 3 loaded lengths in.

However the orthotropic. Ucfse structural 3 feb 15 14 36 depending on your area of practice you may need the effective properties not just the gross properties you would calculate using autocad s massprop command. Analytical expressions for the mechanical properties are studied and compared to finite element calculations in extension free vibration and buckling. The links will open a new browser window.

Moment of inertia of a typical trapezoidal type corrugated sheets. The critical shear load of corrugated sheets. Mass moments of inertia have units of dimension ml 2 mass length 2.

Good similarity is shown in the stiffened and transverse direction of the corrugated sheet. Mm defined in 18 3 ll pressure from live load lbf ft2 kpa. The following links are to calculators which will calculate the section area moment of inertia properties of common shapes. This type of corrugation pattern is formed using circular arcs and straight.

The mass moment of inertia is often also known as the rotational inertia and sometimes as the angular mass. I moment of inertia of corrugated shape in 4 in. Flexural properties of corrcgated metal roofing. Moment of inertia of corrugated sheets.

It should not be confused with the second moment of area which is used in beam calculations.
