ACI 369R-11 PDF Download

The ACI 369R-11 standard serves as a comprehensive guide for estimating the seismic performance of both existing and new concrete components in existing buildings. The guide follows the format and content of ASCE/SEI 41-06, Chapter 6.0, "Concrete," and is specifically designed to be used in conjunction with the analysis procedures and Rehabilitation Objectives outlined in ASCE/SEI 41-06 for the Systematic Rehabilitation Method.

This standard offers recommendations for modeling parameters and acceptance criteria for linear and nonlinear analysis of various elements in concrete buildings, including beams, columns, joints, and slab-column connections. It outlines the necessary procedures for obtaining material properties required for seismic rehabilitation design.

In essence, ACI 369R-11 provides engineers and practitioners with guidance on how to assess the seismic performance of existing concrete frame buildings and offers insights into the rehabilitation design process to enhance their structural safety and resilience in the face of seismic events.
