ANN for Design of GLULAM Three Hinged Arches

We have succeeded in creating an Artificial neural network (ANN) for complete design of 3D one bay structures, built from 3-hinged GLULAM arches, timber purlines and X-shaped timber bracing. A parametric FE design for the complete 3D structure was done using the PANEL option of the FEA M-STRUDL program. A 78 examples series of the 3D structure in the range of 15 to 30 m soans was generated and tested acording to EC5 standards and STEP 5 interpretations, as well by usung the FEA parametric GEOSTAR input for COSMOS/M program concerning the stability of the structures. The results were presented to the NeuroShell 2 for Windows, as a teaching set. Now the run-time version of the NN is able to design in practically "no-time" all of the dimensions of all of the structural and nonstructural elements of the 3D three hinge GLULAM arch structure. The ANN is practically a multidimensional table for (preliminary) structural design of this type of structures.
