The mass timber and wood products industries must innovate new mass timber products that will utilize untapped timber from national, state and private forest lands, and provide ongoing work to mass timber manufacturers between larger building construction projects. Mass timber noise barriers have the potential to fulfill this need and, in turn, boost the economy. Through this proposed project we intend to produce, install and ultimately test this sustainable system in various regions of the U.S.

The overall goal of this project is to enable the use of cross laminated timber (CLT) to construct commercial and other non-residential buildings in High Velocity Hurricane Zone (HVHZ). The 1992 Hurricane Andrew exposed the shortcomings of existing building codes. Recognizing this shortcomings, the Florida Building Code (FBC) incorporated new enhanced provisions which specifically require that the entire building envelope, including the wall and roof systems, must be impact resistant in HVHZ. Currently, CLT is not in the database of a list of building envelope products that comply with the HVHZ standard. The specific objectives of this project are (1) to qualify PRG-320 compliance CLT panels for HVHZ standard by conducting FBC debris impact and wind pressure cyclic tests; (2) to conduct education and outreach sessions to promote the use of CLT in HVHZ, and (3) to identify possible construction projects that may utilize CLT as the building envelope and promote the use of CLT in those projects. The test results generated in this project will be used specifically to gain HVHZ building code approval.
Since the development of Cross Laminated Timber (CLT), there has been a surge in interest in massive timber buildings. Furthermore, recent conceptual and feasibility designs of massive timber towers of 30 or more stories indicate that performance of mass timber structural elements can compete with other building materials in the commercial industry (MGB Architecture and Design et al.). However, in order for massive timber to penetrate the commercial market even further, a solution is needed for long-span massive timber floor systems. Unfortunately, CLT falls short in this area and is unable to span long distances. The hollow massive timber (HMT) panel presented in this thesis offers one potential long-span solution.
