Equipment Grant: Soil-Structure Test Instrumentation

提供资金的仪器系统的目的是实验研究各种土-结构相互作用的现象，如重力对瑞利波在土-基础结构，爆炸引起的土-结构相互作用，应力-应变关系的粒状材料下的冲击载荷，和动态波在复合材料。该仪器系统适用于小规模实验室和离心模型研究，包括一系列高精度数字存储示波器，内置软盘，可永久记录存储从传感器接收的响应（例如，加速度计、速度计、位移计（LVDT）、应变计和压力计），并提供它们的调用和显示。

Funds are provided for an instrumentation system for the purpose of experimentally investigating a variety of soil-structure interaction phenomena, such as; gravity effects on Rayleigh waves in soil-foundation structures, blast-induced soil-structure interaction, stress-strain relationship of granular materials under impact loadings, and dynamic waves in composite materials. The instrumentation system, applicable to both small-scale laboratory and centrifugal models studies, consists of a full line of high precision, digital storage oscilloscopes with a built-in floppy disk which allows permanent record storage of the responses received from transducers (e.g., accelerometer, velocity gage, displacement gage (LVDT), strain gage, and pressure meter) and provides for their recall and display.
