摘要

As the need for seismic retrofit in Southern California increases due to seismic ordinances, some building owners are faced with the requirement to conduct seismic retrofit or to demolish a building structure. A seismic deficiency that is often present on non-ductile reinforced concrete buildings is the lack of sufficient capacity of wall in-plane shear, in-plane flexure and out-of-plane flexural strength. Our company has recently supported the structural engineering community with a method of using advanced composites to address these wall issues that is low impact, cost effective and a relatively fast retrofit alternative. This paper will focus on the FRP design basis, application and detailing - including composite anchor detailing - for wall strengthening. The paper will present test results showing the performance of advanced composites for reinforced concrete wall strengthening; it will also present case studies of its application in the field.
