Abstract
A lamella roof offers a unique architectural feature in its interwoven network of timbers. As a roof system, the stiffness created by the interlocking members results in a curved roof that uses less material than a traditional rafter and purlin design. The goal of this paper is for the reader to be able to create a preliminary design of a lamella roof that will be strong enough to withstand the loads stipulated by the most current ASCE 7-10 Minimum Design Loads for Buildings and Other Structures. This design is facilitated by load tables developed by the author using the finite element method and connection tables in compliance with the National Design Specification for Wood Construction 2005 Edition using the Allowable Stress Design [ASD] procedure. In reality, the values used for this preliminary design will give a conservative design that could most likely be lightened with a more in-depth structural analysis. Testing on a steel lamella model shows inconclusive results when compared to those predicted by the load table program developed by the author and should be investigated further.
