Testing of a T-shaped Precast Concrete Rocking Shear Wall under Multi-directional Loading

Precast rocking shear walls with unbonded post-tensioning provide a low damage alternative to traditional monolithic reinforced concrete shear walls. However, laboratory testing of precast rocking shear walls has been limited to rectangular cross-section, despite the widespread use of non-rectangular shear walls in elevator cores or around hallways. This experimental study supported by National Science Foundation (NSF) aims to address this knowledge gap by conducting laboratory testing of a T-shaped precast rocking shear wall. The T-wall specimen was constructed at 1/3rd scale of a prototype wall and tested under multi-directional loading up to 1.50% drift. The T-wall specimen was 5 in. thick, 5 ft. and 6 ft. wide in flange and web direction respectively, with a loading height of 136.75 in. This data set consists of measured results from the laboratory testing. The data from this project is believed to be useful for future design and numerical modelling of non-rectangular precast rocking walls.
