Abstract In recent times multi-storied urban constructions require no-column space due to several reasons such as space, population, and aesthetic requirements. Especially by placing floating columns at baselevel provide us column free space for parking and free movement of vehicles. These structures often have floating columns, which can be dangerous in actives seismic zones.

Parking spaces, lobby areas, terrace gardens, and other amenities are highly sought-after in densely populated urban regions. Although floating columns can be useful and an achievable choice, it is important to research their structural performance and cost-effectiveness in the event of substantial ground motion imposed on by an earthquake. A building’s overall dimensions, geometry, and shape all impact how it acts and acts when subjected to seismic loads. For this reason, it is necessary to assess how well floating column buildings perform in seismically vulnerable places in comparison to con

The usage of floating columns for additional space is a recent trend that caters to functional needs. The architectural feature known as the floating column responds poorly to earthquakes. As a result, it should be avoided in areas prone to earthquakes.

Abstract: In the present scenario, due to a lack of available space and an increase in population, open space is typically designated on the bottom level of multi-story buildings (both residential and commercial) for parking, gathering spaces, or theatre uses in the current situation.

Abstract The stone column technique is an effective method to increase the strength of soft cohesive soil, which results in a reduction in foundation settlement and an increase in bearing capacity. The topic of restraining creep settlement through the use of stone columns techniques has gained increasing attention and consideration; because stone columns are widely used to treat soft soil deposits, caution should be applied in estimating creep settlement.

This research aims to examine the effect of the area replacement ratio of the floating stone column on settlement behaviour. Soft soil can be particularly challenging in the construction industry due to its low load- bearing capacity, which means it cannot support heavy structures or loads and may settle over time when the soil consolidates under the weight of the structure. Most construction projects use end-bearing columns compared to floating stone columns due to the double-layered consolidation issue because it is hard to predict the settlement behaviour.

Abstract:
A Very Large Floating Structure (VLFS) is expected as a new utilization of ocean space and coastal region. In Japan, there are many feasibility studies about the hydroelastic responses induced by wave forces for the reason of the relative small rigidity of VLFS. The VLFS supported by columns generally shows smaller elastic responses than those of the pontoon type VLFS. In this paper we discuss the hydroelastic responses of the VLFS supported by large number of columns which have one or two wave-free frequencies for heave. We investigate the hydroelastic behaviors of the VLFS in regular and irr

Abstract:
Abstract In the near future, the offshore wind industry will experience a significant increase of turbine size and of floating wind development activities. A floating offshore wind turbine foundation offers many advantages, such as flexibility in site selection, access to better offshore wind resources, and quayside integration to avoid a costly heavy lift vessel offshore campaign. PyraWind™ is a patented three canted column semisubmersible floating foundation for ultra large offshore wind turbines. It is designed to accommodate a wind turbine, 14 MW or larger, in the center of the interconnec

Abstract:
FPSO (Floating Production, Storage and Offloading) has become used increasingly for off-shore gas fields. Most tall pressure vessels such as columns installed in the FPSO are surrounded by topside structures. In general, columns in on-shore plants are supported only by bottom skirts; on the other hand, some of the tall columns on FPSO hulls require intermediate supports in addition to bottom skirts because of large accelerations they are subject to due to ship motion induced by wave loading. In this paper, the effects of the support were investigated considering acceleration distributions and

Abstract:
The coastal and open oceans represent a major, but yet unconstrained, sink for plastics. It is likely that plastic-biota interactions are a key driver for the fragmentation, aggregation, and vertical transport of plastic litter from surface waters to sedimentary sinks. Cruise SO279 conducted sampling to address core questions of microplastic distribution in the open ocean water column, biota, and sediments. Seven stations were sampled between the outer Bay of Biscay and the primary working area south of the Azores. Additional samples were collected from surface waters along the cruise track to

Abstract:
Cruise AL534/2 is part of a multi-disciplinary research initiative as part of the JPI Oceans project HOTMIC and sought to investigate the origin, transport and fate of plastic debris from estuaries to the oceanic garbage patches. The main focus of the cruise was on the horizontal transfer of plastic debris from major European rivers into shelf regions and on the processes that mediate this transport. Stations were originally chosen to target the outflows of major European rivers along the western Europe coast between Malaga (Spain) and Kiel (Germany), although some modifications were made in r

Abstract:
Chemical control of nuisance aquatic vegetation has long been the most widely utilized management tool due to its high level of efficacy, limited environmental impacts, and relatively low cost. However, unprecise application of herbicides can lead to uncontrolled invasive plants and unintended management costs. Therefore, precision herbicide delivery techniques are being developed to improve invasive plant control and minimize impacts to non-target plants. These technological advancements have the potential to enhance aquatic ecosystem protection from invasive species while reducing associated
