Evaluation on dynamic performance of glulam frame structure composed of slotted bolted connection system

Abstract

World Conference on Timber Engineering (WCTE 2014), Quebec City, Canada, 10-14 August 2014.Earthquake-resisting performance of glulam frame structure was evaluated by shaking table tests on a specially designed glulam “double cross shape” specimen composed of slotted bolted connection (SBC) system. By the first vibration test using sinusoidal wave having a maximum acceleration of 800gal, the specimen survived until 80% level of input waves without damage. After renewing SBC system, the second vibration test was done on a same specimen using the JMA-Kobe NS waves having a PGA of 818gal. The specimen survived until 80% level of input without damage but slightly failed by the panel-shear when 100% level was inputted. Earthquake-resisting performance of glulam moment-resisting joints composed of SBC system was considered as satisfactory enough for ductile joint system, but improvement of panel-shear of glulam member itself was recognized as a future research need
