Equipment Grant: Soil-Structure Test Instrumentation

为一个仪器系统提供资金，用于实验研究各种土-结构相互作用现象，例如：土-地基结构中瑞利波的重力效应，爆炸引起的土-结构相互作用，冲击荷载下颗粒材料的应力-应变关系，以及复合材料中的动力波。该仪器系统适用于小型实验室和离心机模型研究，由全系列高精度数字存储示波器和内置软盘组成，软盘允许永久记录从传感器(例如加速计、速度计、位移计(LVDT)、应变计和压力计)接收的响应，并提供召回和显示功能。

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.
