The article presents the development of conceptual models of buildings constructed with using Building Information Modeling software complexes. It describes the advantages and disadvantages of modern additive technologies. Features of their using are specified. Examples of their integration in modern construction are shown. Construction areas for which building models were developed were selected. The main ways of development of construction in the selected areas of activity are indicated. An analysis of current trends in the field of architecture is presented, and a forecast of future architectural trends for the coming decades based on the results provided by 3D Fast Build technology is made. The functional features of the buildings construction of the designated time period are taken into account. They were theoretically integrated into selected objects related to various construction areas, with their further design and modeling in the Autodesk Revit program, taking into account all identified trends and expected functionality.

“…Rapid evacuation during a fire situation in a high rise building is difficult; therefore, it is imperative to control the spreading of the fire as much as possible. Much research has been carried out on fire safety of the light gauge steel frame (LSF) wall system (Dias et al , 2019a; Dias et al , 2019b; Dias et al , 2019c; Dias et al , 2019a; Dodangoda et al , 2019; Imran et al , 2018; Keerthan and Mahendran, 2012a; Keerthan and Mahendran, 2012b; Keerthan and Mahendran, 2014). However, limited research has been conducted on the fire performance of lightweight concrete.…”

Purpose In this study, the insulation fire ratings of lightweight foamed concrete, autoclaved aerated concrete and lightweight aggregate concrete were investigated using finite element modelling. Design/methodology/approach Lightweight aggregate concrete containing various aggregate types, i.e. expanded slag, pumice, expanded clay and expanded shale were studied under standard fire and hydro–carbon fire situations using validated finite element models. Results were used to derive empirical equations for determining the insulation fire ratings of lightweight concrete wall panels. Findings It was observed that autoclaved aerated concrete and foamed lightweight concrete have better insulation fire ratings compared with lightweight aggregate concrete. Depending on the insulation fire rating requirement of 15%–30% of material saving could be achieved when lightweight aggregate concrete wall panels are replaced with the autoclaved aerated or foamed concrete wall panels. Lightweight aggregate concrete fire performance depends on the type of lightweight aggregate. Lightweight concrete with pumice aggregate showed better fire performance among the normal lightweight aggregate concretes. Material saving of 9%–14% could be obtained when pumice aggregate is used as the lightweight aggregate material. Hydrocarbon fire has shown aggressive effect during the first two hours of fire exposure; hence, wall panels with lesser thickness were adversely affected. Originality/value Finding of this study could be used to determine the optimum lightweight concrete wall type and the optimum thickness requirement of the wall panels for a required application.

“…Plaster plates protect and isolate thermal insulation plates at the same time. Hence, they can block the spread of fire during the breaking out of fire [6,7]. Hence, applications of green energy saving plaster and polyphenyl materials are wide, which can promote the innovation of new wall types around the world [8].…”

Since the composition and stress state of thermal-insulation composite plates are extremely complex, it is difficult to conduct calculation using conventional methods. Further calculation on its composition structure is even more difficult. To settle this difficulty, this paper conducted experimental investigations on thermal-insulation composite plate and conventional composite plates, and a simplified calculation method with improved factors was deduced based on the experimental results. In this study, the influence of nonstructural thermal insulation system on the composite plate was specially considered. The calculated expressions are deduced, while the stiffness and damping (properties) are determined. Case analysis was carried out to validate the reliability and accuracy of the simplified calculation method of improvement factor. The research results indicate that the modeling difficulty and computational effort are greatly reduced, with relatively small errors. Hence, it is beneficial to the calculation and analysis of composite plates and global structures.
