Dynamic live loads at a rock concert

A coupled distinct lattice spring model for rock failure under dynamic loads

It is necessary to take into account the micro discretization of natural rock when studying its macroscopic failure behavior. This requirement has resulted in renewed and increased interest in the discrete or framework/lattice numerical modeling techniques. However, to fully construct a numerical model for practical applications using a discrete numerical model is computationally difficult with...

Foundations for Dynamic Loads

Design of foundations in earthquake prone areas needs special considerations. Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. The reduction in bearing capacity depends on the nature and type of soil and ground acceleration parameters. In the case of piles, the soil-pile behavior under earthquake loading is generally ...

Measuring Dynamic Vehicle Loads

• The fifth objective of the AASHO Road Test was as follows: "To develop instrumentation, test procedures, data, graphs and formulas which will reflect the capabilities of the various test sections; and which will be helpful in future highway design in the evaluation of the loadcarrying capabilities of existing highways and determining the most promising areas of further highway research." It w...

Engaging the Crowd at Concert Events

AUDIENCE-PERFORMER INTERACTION There is a very traditional set of expectations to an audience of a performance [5] and augmenting the audience with technologies can introduce complex interaction. This can provide rewarding experiences, but it can also make shows overly complex to run and (for example in the case of audience interaction via mobile technology) create audience split because of fra...
