Earthquake Damage Assessment Instrumentation Study

9360497该项目将审查用于建筑物和其他民用基础设施震后健康监测的峰值应变和挠度仪器系统的设计。仪器系统旨在评估结构内特定点处的局部材料损伤，并用于估计结构遭受的损坏程度和结构的状况。这项工作将需要设计几种类型的传感器，执行完整的静态和动态测试，并调查设计特定于现场的系统和解释传感器输出的方法。将评估地震事件期间产生的高应变(或损害)的一般分布，以优化传感器的位置，以及系统预测破坏的准确性。通过这项研究提供的新技术可以为结构安全评估提供一种经济可靠的手段。样机仪器系统具有开发和应用的潜力。这是SBIR第一阶段项目。***

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. ***
