Abstract

The goal of this project was to research the material properties of the green building material COB in order to better understand how to apply COB in real world applications. The research portion included soil analysis, compression, modulus of rupture and elasticity tests, hydrometer analysis, and atterberg limits tests. Additionally, through a partnership with the professionals of the COB Research Institute team and another COB-centric senior design group, this team was able to produce the first full-scale wall tests for COB. Four 7-foot walls were constructed and in-plane lateral cyclic loading was applied to create the effects of a COB structure under lateral loading. The results of the full-scale tests are in the process of being incorporated in the entry for COB into the California Residential Code, with a recommendation given for the reinforcing design that performed the best, through allowable load and deflection calculations. Finally, the team used a sample footprint for a simple house to develop structural house components for a COB structure that could benefit COB application in the real world. The simulated application of COB is helping the COB Research Institute formulate their submittal and ultimately provide a jumping off point for further research of this nature. The ultimate goal was to spread awareness of sustainable building practices and make them more accessible to the general public.
