The purpose of base isolation is to absorb earthquake energy, prolong the life structure, and enable structure be similar a rigid body. However, since resonance can occur due closeness period structures long large velocity pulses near field earthquakes, stability these buildings greatly reduces, with displacement above level, sometimes, tendency overturning created in isolators leading their de...

This study examines the influence of pressure tap density and layout on estimated wind effects a 47-story steel building for which Database-Assisted Design procedure is used to calculate base shears, overturning moments, member Demand-to-Capacity Indexes (DCIs), inter-story drift ratios, floor accelerations. From an original (20 rows by 5 columns, total 100 taps per façade), 16 cases were creat...

According to design standards, offshore wind turbines need withstand environmental loads with a return period of 50 years. This work compares the extreme response along 50-year contour true turbine response. It was found that method is currently described in IEC standard for can strongly under-predict value variables whose annual maxima typically occur during power production. The bias contour-...

This article addresses the problem of non-circulation information in each stage architectural design. paper explores design process based on BIM platform and puts forward structural method platform. It carries out seismic analysis a high-rise building with transfer floor structure compares results software commonly used by current institute. The obtained for experimentation show that period rat...

Simulations in a three-dimensional numerical wave tank are performed to investigate the shoaling and breaking of a solitary wave over a sloping ridge with a lateral modulation. The model is based on a high-order boundary element method combined with a mixed Eulerian–Lagrangian formulation. Our study is focused on the case of a plunging breaker and is aimed at describing the phenomenon of wave o...

[1] We investigate the sensitivity of the deep meridional overturning circulation (MOC) in the Southern Ocean to changes in the easterly wind stress over the Antarctic continental slope. The deep MOC is driven by export of dense Antarctic Bottom Water from the Antarctic continental shelf, and exerts a strong influence on climate by ventilating the deep ocean with oxygen and storing carbon dioxi...

[1] Abstract: The density structure along the ocean margins carries an integrated imprint of ocean circulation. The difference in pressure between the eastern and western margins of the ocean reflects the net meridional geostrophic transport across the ocean basin. If one assumes that the wind driven circulation is closed in the upper ocean, the wind driven component of the net geostrophic tran...

The processes that govern the predictability of decadal variations in the North Atlantic Meridional Overturning Circulation (MOC) are investigated in a long control simulation of the ECHO-G coupled atmosphere-ocean model. We elucidate the roles of local stochastic forcing by the atmosphere, and other potential ocean processes, and use our results to build a predictive regression model. The prim...

Enceladus exhibits a strong tectonic contrast between its South Polar Terrain (SPT), which is young and geologically active, and its northern hemisphere, which is relatively ancient and stable. Previous global three-dimensional spherical models of convection exhibit patterns that are symmetrical around the equator and fail to explain the formation of a hemispheric dichotomy. Here we present glo...
