Design Fabrication for Modular Structure with Anticlastic Surface

A computer-implemented method for generating a slab design for additive manufacturing, the method comprising:

• receiving, by a processor, design input parameters comprising boundary conditions including (i) span dimensions in a first direction and in a second direction different from the first direction, (ii) depth, and (iii) support locations;
• generating, by the processor, a structural frame model based on the boundary conditions and loading scenarios, wherein the structural frame model defines force flow paths in both the first direction and the second direction;
• determining, by the processor, placement locations for a plurality of internal cable conduits based on the force flow paths, wherein the plurality of internal cable conduits comprises a first set of conduits extending along the first direction and a second set of conduits extending along the second direction to enable post-tensioning in both directions;
• applying, by the processor, a volumetric modeling technique to integrate a periodic anticlastic surface geometry with the structural frame model, wherein the periodic anticlastic surface geometry comprises a triply periodic minimal surface having geometric characteristics including wavelength and frequency parameters;
• generating, by the processor, a three-dimensional mesh model of a two-way floor slab incorporating the periodic anticlastic surface geometry and the plurality of internal cable conduits;
• and
• updating the three-dimensional mesh model based on at least one of a lifecycle assessment and one or more design objectives;
• and
• outputting fabrication data comprising instructions for additive manufacturing of the two-way floor slab.
