### EK-ETA-2

## Engineering Performance Matrix

Structural Analysis concerns the process of determining the effects of loads, or forces, on physical structures, as well as their individual components, and examining what factors influence the deflection and deformation of these structural elements. This includes determining how and why structural elements may fail, break or deform, and preventing such failures. This concept is important to Engineering Literacy as all structures are constantly under some type of strain or stress due to a variety of forces applied to them. As such, structural analyses enable one to make informed decisions about how structures should be designed by performing the proper calculations to determine whether or not various structural members will be able to support the forces applied to them.

## Performance Goal for High School Learners

I can, when appropriate, draw upon the knowledge of Structural Analysis content and practices, such as (a) the physical properties of construction materials, (b) material deflection, (c) material deformation, (d) column and beam analysis, and (e) the implementation of design codes, to evaluate the structural elements of an structure design using the proper formulas and conventions necessary to calculate the effects of applied stresses or strains.
