a collaboration between AOC architects and klokner institute at CTU in prague sees the fabrication of the ultra-lightweight concrete ?bridge over the d?etovice stream.? the project is situated across a walking trail leading to a cemetery outside the czech village of vrapice. the picturesque wildness of its natural context serves to contrast the urban atmosphere of the village. the meadowed landscape surrounding the bridge is subject to constant changes due to the floods. the design of the bridge is driven by the ethereal concept as a ?portal between the world of the living and the dead? and investigates the limits of its extremely lightweight and technologically advanced material.

designers at AOC architects and klokner institute at CTU in prague make use of advanced concrete casting technology in the development of the bridge over the d?etovice stream. with a ten meter span, the structure is fabricated of freeze-resistant, fiber-reinforced, ultra-high performance concrete (UHPC). the subtlety of the form together with the length of its span is overcome with a doubly-curved geometry, stabilizing the construction and easily bracing the bridge in both directions. with a cross-sectional width of 1.5 meters and a total material usage of 1.4 cubic meters, the bridge weights approximately 3.5 tons.
 
 
during the verification of the structural design and the concrete casting technology, a prototype was built and subjected to load testing. pig...
