This paper concerns the numerical analysis of closed rectangular tanks made in one stage, used as pontoons. Such structures can be successfully used as floating platforms, although they primarily serve as floats for ‘houses on water’. Amphibious construction has fascinated designers for many years and is becoming, in addition to a great and prestigious location for many purposes, a practical global necessity. Severe weather phenomena that no country is safe from, i.e., heavy rains or floods, combined with the scarcity of space intended for the construction of residential buildings, encourage development at the contact of water and land or on water only. This paper contains an analysis of the static work of tanks with different bottom thickness subjected to hydrostatic load acting on tank walls and the bottom plate and evenly distributed load acting on the upper plate, i.e., major impacts that occur when tanks are used as pontoons. Calculations were made using the finite difference method in terms of energy, assuming the Poisson’s ratio ν = 0. Based on the solutions obtained, charts were made that illustrated the change in bending moments at the characteristic points of the analysed tanks depending on acting loads. The article also includes calculations of buoyancy, stability and the metacentric height for tanks with different bottom thicknesses, with the main purpose being to improve and share knowledge on their safe use as pontoons.

Liquid plastic films are understood as single- or two- or multi-component polymer or polymer bitumen mixtures. Liquid plastic films must meet the requirements for waterproofing insulation, which means, among others, that they must protect the roof from mechanical damage and have resistance to weather conditions. Suitability for use as waterproofing must be confirmed by an ETA (European Technical Assessment) certificate. The article presents the advantages and disadvantages of waterproofing coatings. The application and division of sealing compounds with a brief description of individual solutions are presented. It was also pointed out that the roof aesthetics would be improved due to the use of renovation solutions in the form of plastic films.

“…Damage is large, the place of occurrence is extensive, and the area covered by such an event is difficult to protect because these actions are often due to progressive degradation [9,10]. For this reason, it is important to locate buildings so that they are least exposed to flooding, inundation, or the raising of water levels ( Figure 2) [11][12][13][14][15][16]. In addition to excessive environmental actions occurring during the use of buildings, other negative phenomena may also occur and can lead to a construction failure or disaster.…”

As climate changes progress we are dealing with violent and excessive environmental actions. However, the impacts of loads acting on a building object caused by unlikely phenomena such as: fire, explosion, flood, vehicle impact, plane impact, excessive snowfall, and excess wind gusts are still being ignored when analyzing the structure of building objects in the combinatorics of loads. The paper presents a multi-criteria approach to accidental actions and analyzes design situations and load combinations in relation to accidental actions. The existing legal acts were used to define the concept of a construction disaster. The authors verified, on the basis of applicable legal acts and design guidelines, individual analysis strategies for ensuring the safety of building objects and divided them into consequence classes of structural damage. They collected and analyzed the number of construction disasters which occurred in Poland between 1995–2019 (25 years) based on the data from the General Office of Building Control. The number of disasters was divided by voivodeships and causes and supplemented with the data on the number of people injured. The article presents the direction of research development that could be undertaken in order to eliminate future catastrophes caused by the omission of the analysis of the impact of accidental actions at the design stage. Statistical analyses were carried out to show whether land use, population density, and weather factors (wind) affect the number of recorded disasters. It has been shown that regions that have preserved the sustainable development of their territories are less vulnerable to disasters resulting from extreme weather events.
