This study is specifically focused on the contribution to the Arizona economy from out-of-state visitors engaged in organized bicycling activities in the state, and out-of-state customers, wholesale or retail, of bicycle products made or sold in Arizona.
Our focus is the development and placement of travel products with key resellers and wholesalers througout China. Arizona remains a relatively unknown destination for the most travel capable highend outbound Chinese tourists. The opportunity for inbound growth from China is tremendous, but the challenges also remain substantial.
This report provides a simplified method to be used for evaluating the skin friction and tip resistance of axially loaded drilled shafts. A summary of literature and current practice was completed and then a comprehensive set of field and laboratory tests was performed. Several soil samples were collected from different sites from Arizona and surrounding states. Large scale direct shear apparatus was developed and used to determine the friction between soil and concrete. Finite element analyses were conducted on several prototype cases to determine effect of soil parameters such as dilation on the skin friction values. A step-by-step simplified approach was introduced to determine the skin and tip resistance of drilled shaft foundations in gravelly soils. An example application was presented to guide users in utilizing the simplified approach.
