Estimation of Yield Load for Unit CLT Connection with Bolt and Steel Plate based on European Yield Theory

Abstract

Estimation of yield load for Cross laminate timber (CLT) bolt connection with steel plate were performed and confirmed by experiments. Estimation were based on the European yield theory. The parameter of estimations and evaluation were connection types (single, double shear with steel attached plate and double shear with inserted steel plate), thickness of CLT (3L3P l=90mm and 5L5P l=150mm) and diameter of bolts (d=12, 16, 20 mm). Calculated yield loads were in good agreement with experimental results in the range of normally used length diameter ration of connector (l/d).
