Testing And Analysis Of A Post-Tensioned Coupled Wall System Monitored With Multiple Digital Image Correlation Systems, Michelle Holloman

Civil Engineering Theses

This thesis discusses the design and experimental evaluation of a novel seismic resistant reinforced concrete (RC) coupled shear wall system. In this system, the widely-used unbonded post-tensioned floor slab construction method is adapted to couple (i.e., link) two RC wall piers, providing significant performance and construction benefits over conventional RC coupling beams in high seismic regions. Previous experiments of post-tensioned coupled wall structures are limited to floor-level coupling beam subassemblies. The current study extends the available research to multi-story structures by construction and testing of a 15% scale eight story prototype specimen. This test is monitored by four digital image …
