Learning Module: ASSESSMENT OF

The proposed educational module will focus on
understanding reinforced concrete column (RCC)
behavior under combined loading (Axial
different design assumptions.
The advantage of using this module is that the students will
be able supplement the materials from class with visual
evidence and comparisons between experimental and
numerically calculated results
The present module contains three main
Video and photos from several
experiments on scaled column
specimens tested under bending
and axial pseudo
static loads will
be available through this interface.
The experimental data will be
generated using the portable
Loading and Boundary Condition
Box (LBCB) placed at UIUC
The student will assess the
axial and bending resisting
capacities offered by the
An additional document will be provided along with the
proposed interface to provide students with a reference on
concrete column design, types of failures and general
instructions to use the excel spreadsheet.
The student will also be able to numerically calculate
the corresponding forces associated with an imposed
relative displacement between column ends. With this
tool the student can calculate the expected relative
displacement to produce forces which will exceed the
capacity of the section.
Compare the numerically calculated forces and the
experimental forces which produce an specific failure
Determine what kind of failure occurred in the
specimen (compression or tension failure),
depending on the steel reinforcement ratio and the
eccentricity of the applied loads.
Propose sections with a design that ensures a ductile
failure (yielding of the steel in the tension side) under
a prescribed eccentricity of applied loads and steel
Improvement of the design tool by adding shear capacity
A complete module, including lecture materials,
homework assignments will be also developed.
Experimental data obtained in partnership with MUST
SIM facility will be integrated into these module.
Feedback will be required to improve the module before
its release (we need users to implement this).
