“…While the assumption of rotation around the corner of the panel is shown to give an accurate estimate of the measured push-over response (Pei et al 2012;Pei et al 2013;Shen et al 2013;Casagrande et al 2016), it is theoretically unconservative because it assumes that an infinite stress can be tolerated at the corner. In reality, the compressive force due to overturning must be transferred over a suitable bearing length at the compression end of the wall.…”

“…In seismic applications, taller hold-down brackets are provided at either end of the panel to resist uplift, while the shorter angle brackets are assumed purely to resist shear. This configuration of connectors is the subject of much experimental investigation into the lateral load resistance of single-storey CLT shear wall systems (Ceccotti et al 2010;Pei et al 2012;Schneider et al 2012;Pei et al 2013;Shen et al 2013;Flatscher et al 2015;Gavric et al 2015;Li and Lam 2015;Popovski and Gavric 2016;Tomasi and Smith 2015;Casagrande et al 2016). Numerical models are proposed which replicate the hysteretic response of timber shear wall systems (Shen et al 2013;Li and Lam 2015;Pozza et al 2014).…”

“…2. Seismic calculations in the literature (Pei et al 2012;Pei et al 2013;Shen et al 2013;Casagrande et al 2016) include a non-linear characterization of the force-displacement response of each connection. Since this information is unlikely to be available to a practising engineer for each type of connection, the methods here assume either an elastic variation of force in the connections, or that they have reached their yield force.…”

Lateral-Load Resistance of Cross-Laminated Timber Shear Walls

et al. 2017

Cross-laminated timber shear wall systems are used as a lateral load resisting system in multistory timber buildings. Walls at each level typically bear directly on the floor panels below and are connected by nailed steel brackets. Design guidance for lateral load resistance of such systems is not well established and design approaches vary among practitioners. Two cross-laminated two-story timber shear wall systems are tested under vertical and lateral load, along with pullout tests on individual steel connectors. Comprehensive kinematic behavior is obtained from a combination of discrete transducers and continuous field displacements along the base of the walls, obtained by digital image correlation, giving a measure of the length of wall in contact with the floor below. Existing design approaches are evaluated. A new offset-yield criterion based on acceptable permanent deformations is proposed. A lower bound plastic distribution of stresses, reflecting yielding of all connectors in tension and cross-grain crushing of the floor panel, is found to most accurately reflect the observed behavior.

“…Several studies have developed numerical analysis models to mimic the performance of light frame wood buildings at a system and component levels (e.g. Gupta and Kuo (1987), Folz and Filiatrault (2004), Collins et al (2004, Doudak et al (2005), Casagrande et al (2015)) with varying levels of complexity. These approaches will be evaluated and suitable modeling techniques will be selected to analyze the tested buildings.…”

Dynamic characteristics of light-frame wood buildings

This research project deals with dynamic field testing of light-frame wood buildings with wood based shear walls. The primary objective of the investigation is to evaluate the code formula for estimating light wood frame building's fundamental period, through intensive field testing and numerical modelling. The project also aims to propose an alternative simplified rational approach where applicable. The thesis provides insight to the ambient vibration testing procedures of light-frame wood buildings and explains the protocol adopted for the current research program. Experimental and numerical investigations were performed to evaluate the effect of non-structural components, and the connectivity between firewall-separated buildings, on dynamic properties of light-frame wood buildings. The study provides a reliable expression for building period estimate based on field testing and numerical modeling.iii
