In recent years, multiple historic and contemporary timber buildings have been instrumented with sensors to monitor the performance of wood products and novel engineering systems. While literature states the potential of structural health monitoring (SHM) data to inform decision-making process of key stakeholders in the architects, engineers, contractors and manufacturers...
Cross laminated timber (CLT) is a relatively new engineered wood product that has elevated the prospects of utilizing wood as the primary structural material for mid and high rise buildings. The hygrothermal performance of CLT, however, is still not well understood at the material, assembly and building scales. A major...
Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...
The two primary considerations for construction project management are budget and time management. Modular construction has the potential to improve construction productivity by minimizing time and costs while improving safety and quality. Cross-Laminated Timber (CLT) panels are beneficial for modular construction due to the high level of prefabrication, adequate dimensional...
This thesis consists of three manuscripts related to the methodology of evaluating charring behavior in cross laminated lumber panel specimens subjected to fire performance tests on cross-laminated lumber panel specimens. The topic of the first manuscript is the measurement of char rates of unprotected CLT layups fabricated with ponderosa pine...
In the last few decades new trends and innovations in wood products have emerged that are changing the way we can use this material in buildings. Additionally, wood is a material that has been touted to have many positive attributes in comparison to nonrenewable construction materials such as steel and...
As mass-timber building construction rises around the globe, there exists the need to verify the long-term, in-situ behavior and performance of these structural systems. Structural health monitoring (SHM), generally defined as a damage detection strategy consisting of a network of sensors, a data acquisition system, and algorithms for data analysis,...
Organizations are significantly influenced by corporate cultures of the interacting organizations. Both the construction industry and engineered wood products (EWP) manufacturing industry are generally known for operating in a traditional environment maintaining conservative corporate cultures, which can create friction when they try to interact with a more liberal architectural industry...
Due to its availability, versatility, structural capability, and economic advantages, concrete is the most widely used material in building sewer networks and other wastewater structures such as treatment stations, wastewater digesters, septic tanks, pumping stations, hydraulic risers, utility risers and covers, etc. Concrete structures exposed to sewer environments can experience...
Chloride binding in Portland limestone cements (PLC) can be attributed to the chemical reaction between chloride ions and carboaluminate phases to form Friedel’s salt and the physical interaction between chloride ions and calcium-silicate-hydrates (C-S-H). This thesis examines the chloride binding of mortar samples containing varying amounts of limestone, fly ash,...
