Structural Engineering

A Guide to Bridge Design and Construction

Bridges are structures that connect two land masses separated by valleys or rivers, but they serve a greater purpose as they bridge the gap between different places, cultures, and societies. Discover how civil engineers construct bridges that win out over the deepest valleys and turbulent waters.

A New WPA For American Infrastructure

American infrastructure is rapidly degrading. Already old and decrepit relative to other nations with developed economic systems, a looming era of budget cuts and limited investment across the board threatens to further undermine the United States’ economic competitiveness as key systems fail.

Science and Technology in Tibet

A government in exile, a parallel government running in the mainland country, natives protesting across the globe against dictating forces, and yet Tibet manages to match its pace with the advancing technology. Science and technology in Tibet is scaling new heights.
S-N Fatigue Curves for Shear Stress

S-N Fatigue Curves for Shear Stress

August Wöhler, a German engineer, studied the fatigue characteristics of materials under cyclic loading. His studies resulted in development of S-N fatigue curves for shear stress. The applications of S-N curves, how to use them, and other major aspects related to Wöhler curves are focused on below.
