The modified compression field theory (MCFT) is a general model for the load-deformation behaviour of two-dimensional cracked reinforced concrete subjected to shear. It models concrete considering concrete stresses in principal directions summed with reinforcing stresses assumed to be only axial.
3D-printed formworks address some of the major challenges of 3D concrete printing. Reinforcement bars can be integrated conventionally, and the conventionally cast or sprayed concrete complies with building codes. Additionally, the surface quality of concrete is significantly better than in 3D concrete printing.
Reinforcement bars are pre-installed, just like in the case of conventionally cast concrete, and the rheology of the concrete is adapted to retain the shape of the slipforming formwork before concrete hydrates enough to sustain self-weight. [14] Concrete facade mullions of varying cross-sections are produced for a DFAB house [15] in Switzerland.
Europe's first 3D-printed residential house. The 3D Print Canal House was a construction project. [67] The first residential building in Europe and the CIS, constructed using the 3D printing construction technology, was the home in Yaroslavl (Russia) with the area of 298.5 sq. meters. The walls of the building were printed by the company ...
Mohr–Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Most of the classical engineering materials follow this rule in at least a portion of their shear failure envelope.
