Axial compression strength of 3D wall panel depends on compressive strength of concrete and aspect ratio of the wall panel, whereas shear strength of 3D panels depends on the number of diagonals (100 or 200 diagonals per sq.m). The flexural strength of 3D slab panels depends on shear span and degree of composite action. The seismic performance of buildings using 3D panels is well understood that forces acting horizontally on 3D panel buildings, due to earthquake forces, are transferred most effectively by 3D shear walls. A frame-like design of 3D buildings with heavy reinforcement in the joints is not necessary. Especially in residential buildings a box-like 3D-structure is the best option to receive high strength and meet architectural requirements at the same time. For dimensioning, 3D slabs and 3D walls can be considered independently of each other.
