Guide for Seismic Rehabilitation of Concrete Buildings: Summary of Future Changes

This paper summarises improvements to the ASCE/SEI 41 concrete provisions considered for implementation in the new ACI 369 Guide for Seismic Rehabilitation of Existing Concrete Buildings. The paper is intended to inform the structural engineering community on the approach being taken by ACI 369 to provide engineers with the latest modeling approaches and acceptance criteria for the assessment and rehabilitation of existing concrete buildings. Through the removal of unnecessary conservatism, it is expected that these modifications will make the seismic rehabilitation of concrete buildings more cost effective.
