Strength-Ductility Type Seismic Retrofit Technique of RC Column with Thick Hybrid Wing-wall using Additional Concrete Sandwiched by Steel Plates and PC bar Prestressing – Part 1 Discussion on Flexural Strength

摘要

Ultimate flexural strength is proposed when longitudinal rebarsyield in tension and wall is in compression in a THW section. Theresults obtained by proposed flexural strength calculationequation have accurate agreement with those calculated by fibermodel on the safe side.
