Cyclic Behavior and Modeling of a Dissipative Connector for CrossLaminated Timber Panel Buildings

This article aims to propose an innovative type of angle to be used in substitution of the hold-down in cross-laminated timber (CLT) panel buildings. The new connection, called XL-stub, applies a concept similar to the classical ADAS (added stiffness and damping) device. In order to characterize the force-displacement response under cyclic loads of the proposed XL-stub, an experimental campaign is presented. Successively, the effectiveness of the proposed angle is proved by analyzing the non–linear response under seismic loads of a single wall alternatively equipped with hold-downs or the XL-stub.
