ITW Structural and Strength of Materials
Teaching Laboratory


Civil & Materials Engineering

UIC

November 2009

Laboratory Needs


Introductory Strength of Materials, Properties
of Materials, and Structural Analysis Courses
are presently offered without laboratory
exercises


These courses are taken by over 600 students
per year


Space is available for the laboratory, and a
new faculty member qualified to supervise the
labs will join UIC in Spring 2010

I


Universal Testing System for
Materials

Basic Concepts
-

Metallic, Cementitious and Composite materials

Important in all basic materials and structures courses

Testing System Requirements for Basic Concepts

Universal Testing Machine


Capability for tension , and compressions tests with load capacities of up to 300 to 500 Kips to
accommodate compression testing of concrete cylinders


Tensile grips and compressions platens for testing of metallic and cementitious materials


Stiff frame for control and accurate measurement of displacements


Fixtures for shear tests either direct or torsion


Flexure test grips fixtures


Environmental test chamber for simultaneous mechanical and


thermal loading of specimens


High capacity silent flow pump for static and fatigue testing of specimens


(25 gpm or higher)


Software for control of test parameters

II


Testing of Materials under High Rates of Loading


Impact Tests


Testing System Requirements for Impact Tests

Drop Weight Impact Testing System


High impact energies (20,000 joules or higher) for testing of a variety of materials
including concrete, steel, and fiber reinforced polymer composites


High impact velocities , i.e. 15
-
20 ft/s


Support fixtures for mounting and fixing the specimens


Test control software

III


Vibration and Seismic Loading


Basic
Concepts


Understand durability of materials under repeated use.


Simulate actual seismic loads on structures


Evaluate Modal Characteristics of structures and machines prior and after damage or
repeated use


System requirements for Vibration Tests


Shaking Tables

Multi
-
axis Shaking Table Test System


Capability for 2 or more degrees of freedom vibration tests


Capability for application of a wide spectrum of frequencies 0.1


100 Hz. With
corresponding displacement strokes.


Capability for accepting mid
-
size structural components, i.e., a concrete column, or a small
-
scale building frame model


Software for load


displacement input control and acquisition and processing of data

IV


Column and Cable Tests

Understanding basic concepts in structural stability of compression members,
i.e. columns

Understanding the basic concepts in the behavior of cables under fatigue and
direct tension load regimes

System Requirements for Cable/Column Test System


Long stroke range test frames for tension testing of cables in cabled structures


Compression tests for columns


3


4 meter specimen length capability


Horizontal design to accommodate laboratory height restrictions and long
specimen loading


Control and data acquisition software
