“…5), this construction has its intrados flattened, aiming at optimizing block cutting by the CNC machine, since a flat surface may be laid on the table. Besides, its spherical shape and design made on the pentagonal blocks aim for better aerodynamics and the creation of a small cycle of winds, that eases the energy of the desertic winds and transforms it into electricity for the resident's use [14,15]. According to Colella [15], recent researches are developing an alternative to the limestone blocks, making possible to harden sand through a solidification process.…”

Stereotomy, as a constructive technique, has a millennial history that has been optimized over time due to the development of geometry and construction . Using mainly stones specially limestone the stereotomic design takes advantage of the subdivision of solid big structures into smaller different pieces, named ´voussoirs´. These pieces are limited in forms and they work through the assembly of multiple units to create the final structure. Precision in the cuts and the correct placement of each part is crucial to ensure static and structural safety. The development of digital technology which has been taking place through the last decades re-ignited the interest in the use of stones as an essential material to buildings structures. As a result, many experiences took place mixing the use of stones with computerized and manufactoring techniques that , in turn, boost the industry of stone cutting. This paper presents information on the use of stereotomic design through the centuries, focusing on its evolution as a technique and on the results that are showing out in contemporary architecture. Through an analysis of the recovery of stone as a constructive and structural material, it is the aim of this study to establish a general panorama on the results achieved in the field of architecture and design in order to understand the methodologies applied when using the stereotomic technique.

“…4 They characterize digital stereotomy as the "union between stereotomy and three-dimensional computer modeling techniques in relation to topological transformations and deformations." 5 Recently, an event entitled "Stereotomy 2.0 and Digital Construction Tools" was held at the New York Institute of Technology showing state-of-the-art research on digital stereotomy through physical models, prototypes, and posters. 6 According to Patrick Schumacher, stereotomy has been "reborn" as 'Stereotomy 2.0' by expanding its traditional formal and material range and scope of application to "systematically integrate material logics as well as engineering and fabrication rationales into the very constitution of its tools and processes, and thus of its formal repertoire."…”

Stereotomy is a traditional construction technique that allows for building architectural structures from discrete stone elements. Stereotomy in this sense is understood as the shaping of solid structural materials to form unique parts that integrally comprise an assembled whole. With the advancement of computational design methods, material properties, and fabrication techniques, the discipline has been “reborn.” In particular, stereotomy can be reinvestigated using materials other than stone such as concrete, or the liquid stone. Concrete has many advantages over stone. Fiber-reinforced concrete can perform in both compression and tension, as opposed to stone which only performs in compression. In addition, the weight of concrete modules can be reduced by using optimized mixes, as well as by designing molds that create hollow spaces in the modules. Concrete is less expensive than stone, and the equipment for its fabrication is widely accessible. Other advantages include the lower cost of concrete compared to stone, and the general economy of material use. In this paper, we present research developed at the LSU School of Architecture investigating the design of stereotomic modules and assemblies made of concrete that comprise a topological, interlocking structural catenary arch wherein variability of form is controlled. Digital tools such as Rhino and Grasshopper were employed to push the boundaries of form generation in the design of the arch, while the Karamba plug-in for Grasshopper was used for structural performance assessment. 3D printing was utilized to make formwork for creating the complex voussoirs. In particular, stereolithography (SLA) 3D printers were employed where elastic resin was used. A small-scale assembly of the arch was 3D-printed, followed by the primary experiments of 3D printing formwork for the modules. This research demonstrates the growing potential of 3D printing for creating stereotomic formwork.

Enhancing the Structural Performance of Masonry Structures by Post-Tensioning

Despite the evident advantages of combining masonry with prestress, their joint use has been poorly exploited during the last decades. This paper claims the high potential of masonry as a primary load-bearing material when combined with post-tensioning. This work deals with arch footbridges and antifunicular structures. With respect to the first, this research illustrates the introduction of external loads by internal post-tensioning to favourably increase the axial forces in a masonry arch, and consequently improving its structural behaviour. With respect to the second, this work shows how bending moments in a non-funicular 2D curved geometry can be eliminated through an external post-tensioning system. In summary, this research strongly expands the range of post-tensioned masonry structures that exhibit a bending-free (or quasi bending-free) behaviour and, de facto, opens up new possibilities for designs that combine structural efficient solutions with traditional materials.
