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.
