CERCADILLO-GARCIA, C.  y  FERNANDEZ-CABO, J.L.. Analytical and Numerical funicular analysis by means of the Parametric Force Density Method. J. appl. res. technol [online]. 2016, vol.14, n.2, pp.108-124. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2016.03.001.

The funicular concept has often been used in different stages of structural analysis and design. This paper presents two new methods: Analytical , A-FDM , and Numerical method , N-FDM , based on a parametric application of the original Force Density Method (FDM ). This is an especially useful way of visualizing a set of solutions and optimizing, i.e. selecting one specific funicular related to a set of constraints. Two structural algorithms are implemented iteratively with Maple ® in real time, and output is also linked to AutoCAD ®. Maple ® facilitates control of geometrical constraints, while AutoCAD ® helps to show all parameterized data. Because of their practical interest, special emphasis is placed on masonry structures using a Limit Analysis approach and preliminary design. Examples of the application of both methods are depicted.
