Setting a higher standard for flush-frame connections

Flush-frame connections 2.0 are here. Steel joists with flush-frame connections offer up to 35 percent weight savings compared to wide-flange beams, while providing equivalent floor stiffness and vibration performance. The post Setting a higher standard for flush-frame connections appeared first on Construction Specifier.

The Efficient Engineer - Understanding the Area Moment of Inertia, 14042020

This video takes a detailed look at the area moment of inertia, how's it calculated, and how it's used. It also covers key related topics, including the polar moment of inertia, the parallel axis theorem and Mohr's circle for moments of inertia.

The Efficient Engineer - Understanding the Deflection of Beams

In this video we take a look at five methods that can be used to predict how a beam will deform when loads are applied to it. These are the double integration method, Macaulay's method, the principle of superposition, the moment-area method, and Castigliano's theorem, which is based on strain energy.

TED Ed (Animation) - Why do buildings fall in earthquakes? 26012015

Earthquakes have always been a terrifying phenomenon, and they’ve become more deadly as our cities have grown — with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be prevented? Vicki V. May explains the physics of why it is not the sturdiest buildings, but the smartest, that will remain standing.
