Representation of Damage Information for Post-Earthquake Damage Assessment of Reinforced Concrete Frames

Abstract

Current practice of post-earthquake damage assessment is based on visual inspections by experts. Research has shown that visual inspection and reports produced as a result of inspections can be subjective, incomplete, and vary in terms of the level of detail and thoroughness. Critical data that provides information about damage can be captured using laser scanners and processed for a more objective and information driven damage assessment practice. In addition to damage information, the damage severity identification process requires reasoning about the structural behavior and topology. Building Information Modeling can be used as the underlying information source to streamline the damage assessment process. This research aims at representing crack information using a Building Information Modeling approach. In order to support reasoning for damage assessment, three activities were performed: 1) requirements were identified based on accepted damage assessment codes and standards; 2) capabilities of Industry Foundation Classes were explored for representing crack information; and 3) suggestions were provided for using existing concepts in IFCs for representing cracks.

Challenges in Generation of As-Is Bridge Information Model: A Case Study

“…Other functional relationships involving the element, and meta information about spatial and physical entities can be represented using "IFCPROPERTYSET" and "IFCRELDEFINESBYPROPERTIES" [7]. Furthermore, Engin et al [8] proposed the idea of using geometry as a representation of defects/damage in buildings. The defect representation and its context can be captured by "IFCREPRESENTATION" and "IFCREPRESENTATIONCONTEXT", respectively.…”

Integrating RC Bridge Defect Information into BIM Models

“…IFC version 2x3 was released in February 2006 and is the most commonly used IFC standard. It can facilitate maintenance information and as-is performance data, such as current condition or damage states for facility management(William East et al 2013).Anil et al used IFC to model damage information for post-earthquake assessment of reinforced concrete frames(Anil et al 2013;Ma et al 2015). More specifically, defect maps were added usingIfcGeometricRepresentationSubContext.…”
