A characterization of the thermal and mechanical properties including compression resistance, density, thermal conductivity and chemical degradation were evaluated in a pilot plant storage tank in contact with solar
Abstract. Refinements are presented on a model proposed originally by Wozniak for the seismic analysis of fluid storage tanks, which forms the basis of the provisions in the American Petroleum Institute design code API 650. It is found that use of the rules in API 650 may lead in some cases to underestimations of the maximum compressive
In the past major damage to liquid storage tanks has been caused by earthquakes and leakage or spillage combined with fire led to considerable harm in addition to the damage of the tanks. Hence, earthquake resistant design of liquid storage tanks has been an
Earthquake-resistant Torre Reforma skyscraper is built to last 2,500 years Written by Lucy Wang on Jul 22, 2016 Design Architecture View
Slender storage tanks on tube feet or skirt support are essential components of industrial facilities and often contain large amounts of hazardous liquid. As the geometry of such storage tanks with torispherical heads is somewhat standardised, seismically induced stresses and anchoring forces are often calculated by the equipment

For the purpose of enhancing the seismic reliability of structures, external energy dissipation systems may be advantageously used. In this paper, the reliabilities of
The behavior of aboveground storage tanks subjected to seismic excitation was investigated using numerical methods by taking flexibility of foundation into account.
However, recent strong earthquakes, e.g., Tokachi-Oki, Japan in 2003 [3], [4]; Emilia, Italy in 2012 [5]; Kaikoura, New Zealand in 2016 [6], have repeatedly shown the vulnerability of storage tanks. Damage to storage tanks may bring economic loss, irreversible consequences for the environment, and retard the recovery rate of the
An early attempt to evaluate the hydrodynamic loads of liquid storage tanks due to earthquakes is found in the work of Housner [5]. The hydrodynamic pressure loading is assumed to consist of a convective component resulting from sloshing motion of liquid at the low frequency range and an impulsive component caused by the lateral
earthquake-resistant construction, the fabrication of a building or structure that is able to withstand the sudden ground shaking that is characteristic of earthquakes, thereby minimizing structural damage and human deaths and injuries. Suitable construction methods are required to ensure that proper design objectives for
Effect of Shock Absorbers in Enhancing the Earthquake Resistance of a Multi-storeyed Framed Building. In: Thomas, J., Jayalekshmi, B., Nagarajan, P. (eds) Current Trends in Civil Engineering . Lecture Notes in Civil Engineering, vol 104.
Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. While no structure can be entirely impervious to earthquake damage, the goal of
Since rectangular containers are used most often for the wet-type storage of nuclear spent fuel assemblies, a typical dimension for those tanks is selected for the following example. Height of the wall, H s =15 m; wall thickness, t s =1.2 m; water depth, H l =12 m; length of the short side wall, 2 Lx =20 m; and length of the long side wall, 2 Ly =60
The core melt accidents at Fukushima Daiichi Units 1-2-3 have occurred due to the tsunami of the Great East Japan Earthquake at March 11, 2011. Now a coolant of approximately 100t is injected into each Reactor Vessel (RPV) in order to cool the fuel debris, and a part of the coolant leaks out from the water. The contaminated water is
The Earthquake Resistance Kit is an optional seismic kit for stabilizing the storage unit rack, so that the rack complies with IBM earthquake resistance standards. The Earthquake Resistance Kit option is available for models 961
In particular, the analysis and design of liquid storage tanks against earthquake-induced actions has been recognized as an important issue towards
13.5 Conclusions. The major source of earthquake risk in terms of human casualty in Nepal is from possible collapse of buildings. More than two-thirds of earthquake risk come from poorly constructed buildings without earthquake resistance. To address this huge risk, intervention on safer construction is required.
