| Abstract: | A new corbelling system with prestressed composite trussed beams is presented in studying feasibility of taking simply dismauntable truss as corbelling for cast-in-place segmental box continuous rigid frame viaduct. The removable flange-slab brackets utilizing the tall piers are put into use for the first time. After a systematic load-bearing test on the ground and the mechanical analysis, a new corbelling lateral slipping construction method is put in practice successfully near the top of high piers of the viaduct. The reliability of the system and obvious economic benefit are verified. |
