【 摘 要 】

Research into deck bridges has been conducted at the Faculty of Civil Engineering of the Technical University in Koice, Slovakia. Encased steel filler-beams in a wide variety of shapes and dimensions were designed for deck bridges, whereby reducing steel consumption by a significant 40 per cent, and maintaining the same resistance and stiffness of the bridges. Our theoretical assumptions were verified by experiments. Specimens were tested for static, dynamic, and long-term loads. Consequently, with the assumptions proved to be correct, a design protocol was elaborated to serve as a template or code of practice for designers and engineers. Using this design protocol, a designer working for Amberg Engineering Slovakia designed a load-bearing structure for the reconstruction of a bridge in the village of Prituany. The proposed technical solution took into account all local restrictions given by the horizontal and vertical alignment of the road structure on the bridge as well as its low building height. The plan of the load-bearing structure as viewed from above (i.e. the angle between the axis of the bridge and the axis of the obstacle being bridged) is oblique.
