Recently, it has been suggested a new formula, confirmed with numerical simulations, which is going to make the prediction of the seismic resistance of reinforced concrete structures easier, based on its capacity to take up and disperse energy.
The director of this work, which has been recently published in the international journal Engineering Structures, is Professor Amadeo Benavent Climent, of the Department of Continuous Means and Theory of Structures of the University of Granada [http://www.ugr.es]. They intend to predict “in case of earthquake, the maximum amount of seismic energy this kind of structures could take up and disperse without risk of collapse”, Benavent Climent explains.
The higher this energy is, the higher the building´s resistance capacity will be. Such energy depends fundamentally on ductility, this is, on the ability of the structure to become twisted without breaking. The new formula allows to assess the seismoresistance of the structures and, comparing it with the seismicity of the area where the construction is located, to draw conclusions about if reconditioning them is necessary or not, whether by means of conventional techniques or by advanced methods like that of energy dispersers. This technique consists of installing special elements in the structure that avoid that pillars and beams suffer important damage in case of earthquake. The next extension of the Architects´ Association of Granada will be the first Spanish building with these special energy dispersers.
One of the present goals for seismic engineering is to control damage (reducing or removing it) in structures subjected to earthquakes. According to current rules of most countries, like Spain, conventional buildings are deigned to, in case of earthquake, experience important plastic deformations but without collapsing, to avoid the loss of human lives. However, allowing such plastic deformations means to admit structurale damages, which can make the demolition of the building after the earthquake advisable.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
