Construction Period 1994 - 1996
The „HYPAR“ is inspired by its math properties – a surface, generated
by two families of straight lines. The structure is 13 x 13 m in plan, height
4 - 6 m, suitable for gas stations - high above the road and low above
people.
The canopy is composed by 4 inclined beams (paired U 240 x 1 m) and
two cross groups of ropes – prestressing and bearing. All prestressing
appliances are hidden in the contour beams, under a removable cover.
The columns’ cross section provides space for lights and advertisements.
Water collecting pipes are inside the columns, so rainwater is not sent to
the wastewater treatment facility. The roofing could be any panels – glass,
plastic, etc. The ropes are rolled circular bars, tendons for larger spans.
A simple double halfpipe at the crosspoints of ropes allows independent
movement. The canopy was mounted on earth to make prestressing easier
to control. After mounting, the upper part of the columns was poured. The
structure is checked for different spans, groups of 4 or more (for sporthalls,
malls, concert halls - acoustic properties not studied yet). The advantages
are a small number of internal supports, separate collection of rain water,
attractive lighting, relatively fast building.
In the 90‘s we did not have any software, later in FEAT we prestressed by
“freezing” the ropes. SCIA Engineer shortens the iterational calculation.

Constructa Ltd is a structural design agency, established in Bulgaria in 2001.
We value our experience in chemical industry, having learned about various
processes and technologies and developed an untraditional approach
towards structural decisions. We start every project with the desire to make
it extraordinary and unique by
interweaving methods, technologies
and
materials
. With the help of SCIA we are able to model specific actions such
as surcharge drift snow loads, thermal loads, explosions and water pressure
on river banks, etc. Our general policy is to study a structure’s work and then
model its behaviour as closely to reality as possible.
