COLLAPSE BEHAVIOR OF CLT DECK WITH STEEL RAILING POST

Abstract

 While CLT(Cross-Laminated-Timber), which is lightweight and is resistant to fatigue, is expected to apply to bridge deck, it is needed to joint commercially available railing on it. It is important to confirm the safety and to investigate the load bearing performance of the joint part between the railing post and the CLT deck. We show relatively simple modeling of the joint part using general-purpose 3D FEM tool and illustrate the numerical results. The modeling considering elasto-plasticity for both steel and CLT members seems to well simulate the sink deformation behavior of CLT.
