Summary
Resilient structures are buildings designed not only to protect life safety in a seismic event but also to preserve the structural integrity of the major components of the buildings so that they can be reoccupied quickly and at minimal cost. An example is a CLT rocking wall system, utilizing post-tensioned cables and energy dissipating-connectors, which is being used for the first time in North America in OSU’s new Peavy Hall. CLT rocking walls borrow from concepts used in concrete and steel structures that were later adapted to LVL building systems in New Zealand. This project will examine the impacts of wetting at the base of the wall on the structural capacity and cyclic performance of the system. Identical rocking wall systems will undergo structural testing, with one being subjected to simulated moisture intrusion that may occur during construction. The findings will provide important information that can be later implemented in design and construction guidelines.

Notes
Building on the results of an earlier project that established protocols for post-occupancy building monitoring, this project aims to install a system in the new Peavy Hall building at Oregon State University to monitor moisture, relative humidity, vertical and slip movements due to shrinkage & deflection, post-tensioning losses, vibration and seismic activity. The monitoring system will establish a “living” laboratory that demonstrates in real time how the mass timber components of the building are affected by various internal and external phenomena. The data will be gathered and analyzed over the service life of the building.

This project aims to solve one of the biggest barriers to increased market adoption of mass-timber buildings - energy consumption. The project team will explore how to replace the concrete typically needed for night flush cooling of thermal mass. The goal is to provide results that will help mass-timber buildings achieve net-zero energy priorities for a larger range of use types and climate zones while also providing new insight into human perception of thermal comfort in mass-timber buildings.

Summary
The research conducted will provide new climatic data which takes into account certain extreme weather events being attributed to climate change to minimize and/or prevent the risk of failure of tall wood buildings and mass timber structures. The project will offer guidance on the design for durability of tall wood building enclosures and fill existing gaps in knowledge about the extent of the effects of the future climate conditions and extreme weather events (e.g. heat waves, rainfalls, wind storms, etc.) on the resistances to deterioration of building materials, air leakage, vapour diffusion, and water ingress.

Summary
A key question about new generation taller wood buildings is how they will perform over time in terms of durability and livability. This project will determine how best to measure these qualities by selecting sensors, determining testing and measurement protocols, and implementing testing assemblies in selected CLT buildings in Oregon. Future research will use the knowledge developed through this project to carry out post-occupancy monitoring, generating valuable new insights into building performance.

Summary
Cross Laminated Timber (CLT) is gaining acceptance in tall building applications in the US. However, there are knowledge gaps concerning long-term performance, particularly effects due to moisture intrusion and biological decay in relation to connection systems. In a risk-averse industry, this knowledge gap impedes acceptance of CLT. The overall goal of the project is to characterize the effects of moisture accumulation in mass timber buildings on properties of building components and connections. The project will assess CLT connectors using small-scale assemblies, then use these data to develop predictive models that will be compared with full-scale tests. Connection assemblies will be constructed with two wood species and exposed to five moisture/biological regimes. Moisture behavior in the assemblies will be characterized using a combination of non-destructive tools, such as ultrasonic, wave propagation, CAT-Scan, and infrared imaging. The data generated from cyclic loading tests will be used to calibrate the SAWS connection model. This will provide a novel way to estimate the effects of moisture and biological degradation on connections. A deliverable for this project is a design guideline for engineers to account for the effects of moisture intrusion and subsequent fungal decay on panel and connection properties.

Summary
Relying on China’s national standard “Standard for Building Carbon Emission Calculation” and related reports published by the Athena Institute, this report calculates the life cycle carbon emissions of wood buildings in China. The study collects basic information of all the projects, such as quantity of building materials, building envelope, energy system and so on. Calculations are conducted for 7 projects from the aspects of product stage, transportation stage, construction stage, operational energy and demolition stage
