Earthquake Damage Assessment Instrumentation Study

该项目将研究基于峰值应变和挠度的仪器系统的设计，用于地震后建筑物和其他民用基础设施的健康监测。该仪器系统旨在评估结构中特定点的局部材料损坏，并用于估计结构遭受的损坏程度和结构状况。这项工作将需要设计几种类型的传感器，进行全面的静态和动态测试，并研究设计特定地点系统和解释传感器输出的方法。在地震事件中产生的高应变（或损伤）的一般分布，以优化传感器的位置和系统预测损伤的准确性将被评估。本研究提供的新技术可为结构安全评估提供一种经济可靠的手段。有潜力的原型仪器系统可以开发和应用。这是SBIR一期项目。＊＊＊

9360497 Westermo This project will examine the design of peak strain and deflection-based instrumentation systems for the post- earthquake health monitoring of buildings and other civil infrastructures. The instrumentation systems are intended to evaluate the local material damage at specific points within a structure and be used to estimate, among other things, the level of damage a structure has suffered and the condition of the structure. The work will entail designing several types of sensors, performing full static and dynamic tests, and investigating approaches to designing a site-specific system and interpretation of the sensor output. The general distribution of high strains (or damage) incurred during an earthquake event to optimize the location of the sensors and the accuracy with which the system predicts the damage will be evaluated. The new technology made available through this study can provide for an economical and reliable means for structural safety assessment. There is a potential that prototype instrumentation systems could be developed and applied. This is an SBIR Phase I project. ***
