the ‘design-phase’, the ‘construction phase’, the ‘use and maintenance phase’,

"To define the project, one first drafts
a plan of action (strategy). This
determines how to proceed in this
phase, what the results should be and
the criteria to which the result of this
phase should be compared. Just like
in the previous phase various aspectstudies
need to be done. Eventually
this leads to the formulation of a report
containing all basic assumptions
concerning the structural design. This
forms a supplement to the PoR.\\\n"

"## Concepts\n",
"\n",
"In this phase too several studies
have to be performed. The designer
makes several ‘structural’ concepts.
To make a sensible design, he
first analyses the force flow in both
horizontal and vertical direction. Also
the ability of the structure to retain
its shape and place is investigated
as well as the connections between
different elements and parts of the
building. After feedback from the
structural assumptions at least two of
the concepts are chosen for further
analysis. With the aid of design tools
(rules of thumb, diagrams and tables)
the overall dimensions of the structure
(including stability measures) are
determined and critical connections
are studied for feasibility. The
sections on different materials contain
information on structural elements
(such as precast conrete beams,
hollow core slabs etc.) and tables
with available (steel) profiles to come
to reasonable dimensions. Already
in this stage it is wise to orientate on
different foundation possibilities as the
foundation can have influence on the
rest of the structure. The section on
foundations can provide the necessary
information. Although the load bearing
structure is designed, this phase is not
yet finished. Finally the designer needs
to look into possible façades and roof
elements. Now a choice can be made
between the different concepts based
on a multi criteria analysis. The criteria
are based on the PoR and structural
assumptions.\\\n"

"Now all the dimensions of the chosen
structure can be determined. Again
the sections on the different materials
can be helpful. Make sure, also in
this preliminairy design, that stability
of your structure is ensured. It is a
good idea to search for alternative
possibilities for the foundation and
connecting structure to prevent
surprises in the final design stage. Also
the building envelope deserves some

"In this phase a further analysis

is checked, and necessary stability
measures are added. To do this, quick
calculations are made with simplified
load combinations. The section on
mechanics offers the necessary
formulas and ‘forget-me-nots’. More
attention is given to the foundation
of the structure. Calculate the total
vertical load and design a transition
structure (which transfers the loads
from the main load bearing structure to
the foundation). Also a further analysis
is made of the possible façades, roof
elements and other building finishes
needs to be made. How are the
building finishes connected to the load
bearing structure?\\\n"
