Pedestrian Bridge over the Railway Yard
The pedestrian bridge of the total length of 400 m is formed by a continuous structure made of prestressed concrete. The bridge deck is formed by two edge beams and a deck slab which will be incrementally launched over the railway yard. Due to strict requirements of the railway authority, the main 87 m long span was designed as suspended in order to minimize the number of supports in the railway yard.
SCIA Engineer was used for a comprehensive simulation of the behaviour of the cable-stayed and pre-stressed concrete structure. The construction stage module allowed us to estimate the initial stage of the structure and determine cable forces. We also used the dynamics module for both a free vibration analysis and seismic analysis. The support stiffness iteration helped us optimise the type and size of the bridge foundations in order to minimize the disruption of the railway yard.
