Quick earthquake damage detection method for bridge structures
When an extreme earthquake occurs, it is essential to detect the severe structural damage that affect the structural safety immediately. This paper proposes a method for quick earthquake damage detection/evaluation of reinforced concrete bridge columns. An intelligent sensor unit is developed that captures changes in the natural period of a bridge column by FFT of response acceleration recorded...
متن کاملRemote Sensing Technology for Earthquake Damage Detection
Remotely sensed imagery data from satellites and airborne platforms have become important tools to assess vulnerability of urban areas and to grasp damage distribution due to natural disasters. The platform and sensors of remote sensing should be selected considering the area to cover, urgency, weather and time conditions, and resolution of images. Satellites with optical and/or SAR sensors can...
متن کاملDamage Detection in Beam-like Structures using Finite Volume Method
In this paper the damage location in beam like-structure is determined using static and dynamic data obtained using finite volume method. The change of static and dynamic displacement due to damage is used to establish an indicator for determining the damage location. In order to assess the robustness of the proposed method for structural damage detection, three test examples including a static...
متن کاملBuilding Damage Detection from Post-earthquake
The collapsed buildings due to earthquake were detected from post-event aerial images using watershed segmentation algorithm. The objective was to detect the collapsed buildings based on the analysis of the cast shadows. The building boundaries were available and stored in a GIS as vector polygons. The building polygons were utilized to perform assessments in a building specific manner. The app...
متن کاملAn Integrated Earthquake Damage Detection System
An integrated damage detection system, which was developed to detect the collapsed buildings due to Kocaeli earthquake, occurred on 17 August 1999, is introduced. The implementation of the system was carried out in a selected area of the city of Golcuk, TURKEY. The developed system is composed of three components: (i) input, (ii) analysis and (iii) output. In the input component, the post-event...
