Structural Engineering and Geometry

July 14th, 2008

Structural engineering and geometry are intertwining subjects. Since the very first Egyptian structural engineers began building pyramids, geometry has been used to help solve structural stability problems. Geometry has been woven into the development of structural engineering for centuries.

What is Structural Engineering?

A structural engineer’s goal is to design structures that can both support and resist loads. A structural engineer designs structures and analyzes them for structural soundness. Structural engineering is closely related to architecture.

Normal Stress, Bending Stress, & Shear Stress

December 4th, 2007

Stresses in Beams
In a separate article entitled “Structural Analysis of a Beam” there was a brief discussion of stresses and their function in structural analysis.  In this article there will be a more in dept discussion of normal, bending, and shear stress.

Normal Stress
A normal stress is a stress that occurs when a member is loaded by an axial force.  The value of the normal force for any prismatic section is simply the force divided by the cross sectional area.

Normal Stress

A normal stress will occur when a member is placed in tension or compression.  Examples of members experiencing pure normal forces would include columns, collar ties, etc.
