Research on Practical Design Method of Single-Layer Lattice Shell Components
There are some limitations on the calculation about effective length factor of the single-layer lattice shell structure`s component by the current specifications. That`s why Euler formula is commonly used to anti-push the effective length in engineering design. In traditional design, one or few components were used to calculate the effective length factor, and the single biggest value is assigned to all components for design. Owing to the coarse method, values of some components` effective length are too large or too small. This paper improved the traditional design method, and used excel in formula programming to calculate effective length factors of all components. Then all factors are assigned to all components for designing by SAP2000. At the end of the article, it explored the difference in this new design method with the traditional design method.
