deformable metal, which can be simply trimmed to construct small-scale shell foundations with various angles and shapes. To attain a uniform structure without nodes and hinges, each model footing... bearing capacity in an unreinforced slope condition, utilization of shell footings rather than a simple footing is concluded as an effective solution; so that, the improvement of the bearing capacity......
