ARUP'S GEOMETRIC PUZZLE PUTS MORRISON ON THE MAP

Construction of the post-tensioned concrete box girder viaduct Kylesku bridge in the Scottish highlands is now back on schedule. The 275 M long bridge designed by Ove Arup and constructed by Morrison is being built on a site where winds of speeds between 80 and 100 km/h have been frequently recorded. A feature of the design is the eight pier legs which rise as four v-shaped supports, two each side of the navigable channel. Construction of these pier legs has proved difficult in the setting out of the falsework and formwork. The undersides of the legs are inclined at 45 deg longitudinally, the pier leg side walls are further inclined 16.5 deg to the vertical and the legs taper longitudinally. Originally it was intended to cast the outward leg of the V supports first, then switch the falsework to construct the seaward legs but difficulties experienced in pouring and placing the concrete, in addition to the poor weather, led to the inclusion of extra falsework so that both legs could be constructed simultaneously. Also, the central 40 M length of the main span is now to be precast and then floated out on a barge and jacked up to connect up with the initial 20 M of the span built in five incremental cantilever stages. When in position the central precast unit will be stressed in the main deck structure. (TRRL)
