Cyclic Testing of two HGA10 connectors for CLT panels

Project Duration: 2/2014~9/2014  
Research Assistant: Brenda Hodgell
Project type:
Undergraduate Research Project

Cross Laminated Timber (CLT) is a building material that was developed in the 1990’s. Initially it was primarily used in Europe. Slowly it has been gaining popularity as a building material in the United States. However, it is far from being commonly used. It is used as a steel or concrete substitute for framing.

CLT is composed of three or more layers of lumber that are adhered together. The layers are stacked crosswise to increase durability. Figure 1 shows how the layers are arranged. CLT has a number of advantages including the following:

         • Low material weight with comparable strength

         • Seismic performance

         • Versatile

         • Made from renewable resources

         • Low jobsite waste

         • Prefabricated for fast and easy installation

         • Carbon absorption for Green building  

 A monotonic test is performed in order to develop the cyclic loading protocol. Then, the cyclic test will be performed. The data collected from this test will complement similar testing being done at Clemson University in South Carolina.
