Previous research has shown that CLT panels can include areas with a range of adhesive bond strengths, including zones of delamination, within a single panel. This study aims to assess how much of the variation in adhesive bond strength is due to variation in the thickness of individual laminations within the panel layups.
The purpose of this project is to assess the utility of resistance drills for mass timber, in terms of what features can be detected, how early they can be detected, and if they can be differentiated from other features. It also aims to develop methods and tools that can be used to monitor the structural health of standing structures and inform the early identification of issues.
The primary goal of this project is to enhance the durability of mass timber assemblies in high-moisture, high-termite risk regions. Only a few U.S. jurisdictions allow mass timber use by code adoption.
Earthquake engineers are focusing on performance-based design solutions that minimize damage, downtime, and dollars spent on repairs by designing buildings that have no residual drift or “leaning” after an event. The development of timber post-tensioned (PT), self-centering rocking shear walls addresses this high-performance demand.
The development of engineered wood-based products such as Cross Laminated Timber (CLT) is creating new opportunities for the development of versatile and resilient structural designs.
This project aims to develop a commercially viable wood adhesive for CLT that is free of formaldehyde and isocyanates and possesses good cure speed properties.
This project will undertake a comprehensive analysis of the effects of water exposure, in various forms, on mass timber building elements. Water intrusion is mostly commonly seen during construction, but can also occur during failure of roofs or external facades or as a result of internal plumbing failures.
A technical team from OSU’s Department of Wood Science and Engineering and School of Civil and Construction Engineering are narrowing down combinations of materials for testing. Proposed solutions include an asphalt topping on the CLT decking, similar to those often used on timber bridge decks.
