Title - City, Country 149 SE AP Category 4: Special Projects 4 Owner Wanted Architect arch. Plamen Marinov General Contractor Transstroy Ruse Engineering Office Constructa Ltd 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.

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.
