This 8-hour course (on-site, on-demand) explores the use of movable scaffolding systems (MSS) for span-by-span and balanced cantilever construction of prestressed-concrete bridges.
Download this milestone publication of Dr. Rosignoli (1998, ASCE Journal of Bridge Engineering) on the pre-sizing and design optimization of incrementally launched bridges.
This 8-hour course (on-site, on-demand) provides exhaustive coverage of span-by-span and balanced cantilever construction of precast segmental and macro-segmental bridges.
The combined use of external post-tensioning and steel corrugated-plate webs leads to light, efficient bridge superstructures that are less expensive and simple to maintain.
Download this long publication of Dr. Rosignoli (2010, PCI Journal) on the loads, kinematics, performance, productivity and structure-equipment interaction of self-launching gantries.
Short-line match-casting operations have a critical role in assuring geometry control, quality and durability of precast segmental bridges and in avoiding premature joint failure.
Simultaneous erection of adjacent decks with side-shifting self-launching gantries is lowering the entry threshold of balanced cantilever construction to 50-55m constant-depth spans.
Computer simulations analyze construction processes, process performance under different conditions, functional relations, process sensitivity, bottlenecks, and process optimization.
Span-by-span construction with self-launching gantries is the most common, and often the most cost-effective, construction method for precast segmental bridges.
