You have been tasked with determining effective cross$-$sectional properties of a CLT floor. The panel is a $2005$ s $(60/30/20/30/60)$ floor panel of C$24$ timber that spans $L=5\mathrm{.}0m$ between supports $($for both major and minor orientations, as shown below$).$ The panel sits on top of a $50$ mm thick stud wall at each end, and may be modelled as simply supported.

In your analysis, please consider a $1$ m panel width. The rolling shear properties are given by: $G_R=50$MPa and $f_{R,k}=2\mathrm{.}5$ MPa

Major orientation:

Minor orientation:

$L$

Your task is to:

Find the effective rigidity in the major direction

Find the effective section modulus $($bending$)$ in the major direction

Find the effective rigidity in the minor direction

Find the effective section modulus $($shear$)$ in the minor direction

FINAL ANSWERS
