employed corten steel, which has high levels of embodied energy, can be used
without additional energy for other functions (the structural module can become
something else without other processes);
4. End of building life (Faludi et al. 2012): reversibility of the foundation system:
once unscrewed the screw foundations, the ground returns to its original state
without any damage; disassembly of the components: all connections are made
with clamping and thus easily separable systems; reuse of the container: the basic
structure can be reused without heavy interventions; reuse of the casing components: both the finishes and the thermal insulation are mechanically fixed, so that
they can be easily dismantled and reused; recycling of container components: as
a last opportunity, the container is made of corten steel which can be used as a
second raw material;
5. ‘End of life’ of the main function. Transformation of its component parts: disassembly of the components; reuse of the envelope components; reuse of parts of
the container’s metal sheet.
The project uses the container as a structural resource. The employed module
ensures high-structural performances, without introducing additional elements for
the system stability (Bernardo et al. 2013).
We have studied operations to make this structure habitable. First, living space has
been well conformed through the right aggregation of basic modules. Subsequently,
the right functions have been included into the structure and the essential spatial
characteristics have been applied. We followed the basic principle of maintaining a
high degree of techno-typological and spatial flexibility for each space, while also
guaranteeing the possibility of future extensions or changes in use.
4.1 The Mock-Up
The mock-up we are assembling is a 2-storey building. It consists of 4 HC 40
, linked
by an ‘other space’ made of a steel autonomous structure (Kotnik 2008; Kramer
2015). It will simulate different technical solutions and real-use conditions. It will
be placed in eastern Milan suburbs (Fig. 2).
From a structural point of view, the main purpose is containing goods. Containers
(Giriunas et al. 2012) have to provide a suitable resisting structure as well, so that
no meaningful change in shape can occur under the effects of both weight and the
different actions which may take place during the various phases of transportation
and movement. Looking at the terminology, indeed, the term ‘box’ applies to the
main function as well as the structural scheme. The main goal of the project is to
limit additions to frames around the cuts and to avoid braces: for this reason, we
have obtained the maximum hole the metal sheets are able to bear in normal and
earthquake conditions in relation to buildings.
The foundation system is based on totally reversible screw poles, without concrete
or other non-easily dismountable solutions. With respect to seismic protection, we
