In Japan, it is increasingly common to monolithically construct exterior concrete wall cladding elements to beams and columns, with wall gaps present at plastic hinge locations along beams and reinforcing bars cut at the base of ground floor wing walls to minimize wall damage. This study evaluates the cost-effectiveness of this detailing considering initial construction and damage repair costs. It was found that this detailing resulted in lower drifts and probability of requiring demolition or collapsing, but greater total accelerations. Cost-benefit assessment showed that the monolithic wall construction approach has a time to return-on-investment of 13 years over a bare frame alternative, indicating that there are financial benefits for implementing such systems.
