Full-scale experimental testing and finite element analysis of a totally prefabricated counterfort retaining wall system

摘要

The overall structural behavior of a totally prefabricated counterfort retaining wall system was examined experimentally and analytically using nonlinear finite element analysis. A 20 ft 2 in. (6.09 m) high, 13 ft 10 in. (4.21 m) wide full-scale prototype was designed meeting the requirements of the AASHTO LRFD specifications, assembled, constructed, instrumented, and tested in a precast concrete plant. The design was optimized and validated using nonlinear finite element analysis. Five headed anchors extended from each counterfort and were grouted to the base slab using truncated conical shear pockets to ensure full connectivity between the precast concrete components.
