ACI 369R

Abstract

This guide describes methods for estimating the seismic performance of concrete components in an existing building. The guide is intended to be used with the analysis procedures and Rehabilitation Objectives (ROs) established in ASCE/SEI 41-06 for the Systematic Rehabilitation Method. The methods described apply to existing concrete components of a building system, rehabilitated concrete components of a building system, and new concrete components added to an existing building system. Provisions of this guide do not apply to concrete-encased steel composite components. <br>Chapter 2 recommends data collection procedures for obtaining material properties and performing condition assessments. Chapter 3 provides general analysis and design requirements for concrete components. Chapter 4 provides modeling procedures, component strengths, acceptance criteria, and rehabilitation measures for cast-in-place concrete moment frames.
