| Sumario: | This chapter reports on the finite element analysis of the “earthscraper,” proposed by BNKR Arquitectura. It was proposed as an alternative building method for the future, as it requires less surface area and lower operating costs than an equivalent aboveground structure. A 2D model of the cross section of the structure was created using Strand7 for steady-state thermal analysis. This solver gave internal temperature ranging between 20 and 38°C between the bottom apex and the surface, respectively. This provides a comfortable temperature by default, displaying the lesser dependency on heating and cooling costs. A 3D model was also created to analyze the effect of lateral earth pressure by the use of the linear static solver. Results give a maximum lateral displacement of 527 mm and 19.8 mm on the exterior and interior walls, respectively. The model was used for earthquake analysis in accordance with AS/NZS1170.4, requiring the natural frequency and spectral response solvers. Twenty-five modal frequencies were found, with 99.6% of the mass of the structure contributing to the direction under analysis. The maximum horizontal displacement of the structure under the designed earthquake loads was found to be 19.2 mm. |
