Summary
This paper describes experiments conducted to develop a resilient lateral force resisting wall system that combines cross-laminated timber (CLT) panels with vertical post-tensioning (PT) to provide post-event re-centering. Supplemental mild steel U-shaped flexural plate devices (UFPs) are intended to yield under cyclic loading while the PT...

Summary
Compression tests were conducted on the glulam members under different eccentricities, including three cases of 0mm,50mm and 100mm respectively, to study the mechanical performance of the new assemblage joints in reticulated timber shells. The bending stiffness and bending capacity of joints were evaluated, at the same time, the influence of failure mode and the changes...

Summary
Cross-laminated timber (CLT) wall systems are composed of massive timber panels that are fastened together and to the horizontal elements (foundations or intermediate floors) with step joints and mechanical connections. Due to the high in-plane stiffness of CLT, the shear response of such systems depends strongly on the connections used...

Summary
The goals of this research are to gain a better understanding of the mechanics of timber moment-frame connections during two different fire scenarios: fire and post-earthquake fire. This research will develop the testing methodologies and benchmark data required to develop designs for the fire and post-earthquake performance of timber moment-resisting frame connections. The project wIll test two moment resisting frame connections under fire and post-earthquake fire loading scenarios. Full scale monotonic and cyclic loading tests on sub-assemblies for both connection types at the Emmerson lab. Fire testing of structurally tested and un-tested specimens at the National Research Council (NRC) of Canada. These tests will occur under service loading conditions and will measure temperature gradients through the cross section of the connection, as well as displacements between the beam and column and residual cross section dimensions. Data will be used to benchmark numerical models in order to perfom a parametric study that allows for varying of geometric parameters such as connection geometry and fastener configurations.

Summary
This paper presents an experimental evaluation of the fire resistance of glued-in rod timber joints using epoxy resin, with and without modification. A heat-resistant modified resin was designed by adding inorganic additives into the epoxy resin, aiming to improve the heat resistance. Joints that were made using the modified epoxy resin at room temperature showed a bearing capacity comparable to those with commercial epoxy resin. Twenty-one joint specimens with the modified epoxy resin and six with a commercial epoxy resin were tested in a fire furnace to evaluate the fire resistance. The main failure mode was the pull-out of the rod, which is typical in fire tests of this type of joints. As to the effects of the test parameters, this study considered the effects of adhesive types, sectional sizes, stress levels, and fireproof coatings. The test results showed that the fire resistance period of a joint can be evidently improved by modifying the resin and using the fireproof coating, as the improvements reached 73% and 35%, respectively, compared with the joint specimens with commercial epoxy resin. It was also found that, for all specimens, the fire resistance period decreased with an increase in the stress level and increased with an increase in the sectional sizes.
