Abstract
The seismic performance of the Distributed Knee-Brace (DKB) system was investigated as a retrofit option for weak-story wood-frame buildings. The performance of the DKB system was evaluated numerically using simplified hand calculations and 2D non-linear dynamic analyses. The numerical simulation results were validated using: (1) reversed cyclic tests of two, four-frame, full-scale test specimens each with different knee-brace configurations; (2) dynamic testing of one of the configurations; and (3) slow pseudo-dynamic hybrid simulation of a three-story wood-frame building with the DKB system retrofit. The DKB system proved to be a viable retrofit option for weak-story buildings with acceptable load-deformation characteristics.
