The design of vaulted structures is living a true renaissance thanks to the computer aided graphic statics. The fundamental work, mostly done by Block, have brought a series of computer tool for the research of the vault form by analyzing the thrust network lines. This thesis firstly explores the load-carrying efficiency of different piercing pattern of a simple vault, generated by RhinoVault. As a main result, from FEM analysis, the more stable pattern was found in the uniform distribution of 29 holes along the diagonals. As a second stage, the more suitable tessellation of the voussoirs was examined to guarantee both equilibrium and manufacturing.
