General plane and space frame stiffness matrix solutions are provided as well as free solutions for portal frames, multi-span beams, slabs and beams on elastic foundations. Results have been verified by a commercially available structural analysis software program. The lowest natural frequency is calculated for the footbridge grillage models. Integral or ‘ladder’ type decks can also be analysed using rotational springs or by omitting supports. Grillage models * based on stiffness matrix analysis are available for 1- or 2-beam footbridges, 4-, 6- and 8-beam normal or skewed 1 to 3-span bridge decks, deck slab, abutment and wing walls. ![]() ![]() ![]() Structechnique is a provider of low-cost Excel* spreadsheet solutions for civil and structural engineering elements and design related issues.
