Low-disturbance sustainable urban construction 9/10 C ONCLUSIONS SLS and ULS have been fulfilled for the designed span length (2.40m) The deck behaved perfectly elastic for the design loads. The deck was destroyed after increasing length of the span to 4.80m. The weakest point of the panel is adhesive connection. High correlation between the measurements and numerical model was observed. Brittle rupture of the panel - a large role of testing elements in real scale. In the next year, the first commercial application of the developed deck panels is planned.
