Shear capacity prediction of Acacia mangium crosslaminated timber under out-of-plane bending

Kundari R., . and Achmad B., . and Halwan Alfisa S., . and Buan A., . (2025) Shear capacity prediction of Acacia mangium crosslaminated timber under out-of-plane bending. Journal of Tropical Forest Science (JTFS) (Malaysia), 37 (1). pp. 49-57. ISSN 0128-1283

The popularity of cross-laminated timber (CLT) in construction has increased globally. In Indonesia, effort has been made to utilise local wood such as Acacia mangium in CLT production. The characteristics and properties of acacia CLT have not been studied in depth. Our study determined the shear capacity of short-span acacia CLT panels subjected to out-of-plane three-point bending tests and evaluated selected models (shear analogy method, gamma method, simplified composite beam method, and simple beam theory) in their ability to accurately estimate shear capacity. The simple beam theory (CSA086-14) gave predicted shear capacity values closest to the experimental results for three-layer acacia CLT samples (14.05 kN and 18.45 kN vs 13.7 kN and 18.06 kN for the 51 and 67 mm-thick panel samples respectively).

Abstract

The popularity of cross-laminated timber (CLT) in construction has increased globally. In Indonesia, effort has been made to utilise local wood such as Acacia mangium in CLT production. The characteristics and properties of acacia CLT have not been studied in depth. Our study determined the shear capacity of short-span acacia CLT panels subjected to out-of-plane three-point bending tests and evaluated selected models (shear analogy method, gamma method, simplified composite beam method, and simple beam theory) in their ability to accurately estimate shear capacity. The simple beam theory (CSA086-14) gave predicted shear capacity values closest to the experimental results for three-layer acacia CLT samples (14.05 kN and 18.45 kN vs 13.7 kN and 18.06 kN for the 51 and 67 mm-thick panel samples respectively).
