Abstract

This study is done to develop a concrete damage condition rating examination method for existing buildings based on visual assessment, changing it from a qualitative assessment to an assessment that can be measured quantitatively. Structural damage greatly affects building safety and will result in reduced building performance, or even building failure. Existing building structure damage is caused by many factors, one of which is poor construction implementation. To identify the extent of damage done, concrete structure condition rating assessment needs to be performed on the existing building. Assessment must be performed, either on functioning buildings or on post-disaster buildings, in order to provide an image of a buildings condition and provide alternative steps that can be taken for a building in a bad condition. Right now, there is no clear reference that can be used to perform concrete damage condition rating assessment on existing building structure, so assessment results tend to be qualitative. This research suggests a concrete damage condition rating assessment method based on visual assessment. This assessment method has a scale and a condition rating reference, so that the resulted concrete damage condition rating assessment can be measured quantitatively. Aside from that, this assessment method also considers the critical weight and damage area of each concrete structure element on existing buildings. That way, the resulted assessment method can accommodate the need for visual-based concrete damage condition rating assessment for existing buildings.
