WebJan 17, 2024 · The calculation method for buckling capacity of cross-laminated timber (CLT) under axial load with one-way members has been investigated and incorporated into design codes worldwide. However, the load may only be applied to a part of the CLT members. In this case, the available calculation method for buckling capacity is not applicable. To … WebStruts Slenderness Ratio (𝑳𝑳⁄𝒌𝒌) The slenderness ratio is defined as the ratio of the length (𝐿𝐿) of a strut to its radius of gyration (k) for the axis about which buckling will occur. This is the axis with the least radius of gyration if end fixings of both the xx and yy axes are the same.

WebThe radius of gyration can be thought of as the radial distance to a thin strip which has the same area and the same moment of inertia around a specific axis as the original shape. Compared to the moment of inertia, the radius of gyration is easier to visualize since it’s a distance, rather than a distance to the fourth power. 🔗

WebThe radius of gyration represents the distance from a section's centroid at which all of the area could be concentrated without having any effect on the moment of inertia.
