STEEL JACKET RETROFITTING OF REINFORCED CONCRETE BRIDGE COLUMNS FOR ENHANCED SHEAR STRENGTH--PART ONE: THEORETICAL CONSIDERATIONS AND TEST DESIGN
A theoretical and experimental investigation conducted to study the shear failure mode of reinforced concrete bridge columns designed before 1971, and to establish the effectiveness of full-height steel jackets for enhancing the seismic shear strength is described. In this first part of a two-part paper, theoretical considerations relating to assessing the shear strength of existing columns of circular or rectangular sections are presented. Current design approaches are compared with more recently developed, and less conservative, predictive methods. Models are presented for predicting the enhancement to shear strength provided by circular or elliptical (for rectangular section) jackets. Design details of an experimental test program to determine "as-built" and retrofitted column shear strength are presented.
