Experimental Study of Disproportionate Collapse Resistance Mechanisms for Mass-Timber Buildings
Publication: Structures Congress 2019: Blast, Impact Loading, and Research and Education
ABSTRACT
The recognition of wood as a viable and sustainable alternative for construction has promoted the use of mass-timber panels in mid- to high-rise residential and commercial buildings. To safely expand the application of mass-timber constructions as post-disaster, military/federal, and high-rise buildings, studies with respect to disproportionate collapse prevention are required. Being a new method of construction, however, such studies are scarce and to date limited to numerical investigations. This paper presents the methods for experiments that evaluate possible catenary action as a resistance mechanism for disproportionate collapse preventions for mass-timber floor systems. Testing is performed at component level, with conventional and novel timber connection detailing to estimate the load-carrying and deformation capacities, in order to ensure adequate load distribution while undergoing large deformations without failure. The work will provide practical economic collapse-thresholds and define disproportionate collapse acceptance criteria for mass-timber floor systems to ensure structural safety after extreme load events.
