MANUFACTURED AWNINGS
DESIGNING & LOAD TESTING AWNINGS
PROBLEM
The client approached CMF with assistance in designing, manufacturing, and testing awnings for their newly constructed modular structures. They emphasized the need for the awnings to be noncorrosive, compliant with International Building Codes (IBC), and aesthetically appealing. Additionally, they have had previous challenges during the installation of awnings on-site. They highlighted the need for a simplified bolted design with high tolerance for adjustment.
SOLUTIONS
CMF took the design specifications derived from the customer and established a CAD model. It was decided that 6061 Aluminum was the optimal material due to its lightweight and corrosion resistant properties. To accommodate hole tolerance, slotted connections were applied to the tiebacks. Furthermore, we conducted FEA analysis to simulate distributed loads across the awning. Once verified, we performed an experimental study by applying loads to a prototyped awning.
RESULTS
With a lightweight material and high hole tolerances implemented in the design, this allowed for a effortless installation of the awning in the field. The experimental study demonstrated that the awning could withstand up to 80 pounds per foot with minimal deflection. This was verified and stamped by a professional engineer, ensuring that all manufactured awnings now comply with IBC codes. As a result, these awnings are now a regularly manufactured component for the customer.
