Abstract

Electric scooters are rapidly involved in our life, and every year their lease increases and spreads to more cities. Urban infrastructure never keeps up with progress and cannot provide these vehicles with the appropriate infrastructure. In this regard, it is important to solve problems of adapting modern means of transportation with respect to comfortable and safe traffic.

Purpose: The analysis of the current situation with personal mobility devices and their impact on the urban environment.

Methodology/approach: Sociological survey and analysis of improving amenities environment to ensure the operation of personal mobility devices.

Research findings: The analysis of introduced traffic rules for personal mobility devices in 2023, where the status of transport is officially assigned to electric scooters. there is a need to separate roads and create the bicycle path infrastructure to minimize accidents. Results show positive and negative consequences of using electric scooters in cities. It is shown that the urban environment quality index in different cities is determined by the distance of bicycle paths in cities.

Abstract

In Vietnam, the concept of building information modeling (BIM) has become quite popular in the construction industry. The BIM application optimizes the information exchange and coordination between participants in various project, helps to visualize design, construction and project management processes, ensures the project quality and various benefits at a later stage of the project management and operation.

Purpose: A review of the current situation and trends of BIM application in construction investment projects as well as inevitable digital transformation in the construction sector of Vietnam.

Methodology: Statistical and comparative-historical methods, survey data obtained through a questionnaire in the form of statistical analysis using charts describing the BIM application in the construction industry in Vietnam.

Research findings: It is shown that BIM is mostly used by enterprises that directly benefit from modern technologies. The BIM reflects the diversity of research subjects, as is can be applied at different stages by many project stakeholders. It is found that many surveys are distributed rather evenly, confirming that all key project participants are interested in using BIM.

Originality: This study supplements information on the current status and trends of the BIM application in construction investment projects in different countries, including Vietnam. Thus, the BIM is increasingly being used in the construction industry, but there is still a lack in qualified personnel who can use this technology.

Abstract

Purpose: The assessment of risks and prediction of reliability of complex engineering systems, in particular onshore gas pipelines subjected to external corrosion. Two methods are proposed using the structural reliability analysis.

Methodology: Two strategies are considered for inspection and maintenance service of hazardous production facilities.

Research findings: The model of structural reliability is proposed to estimate the metal rupture from external corrosion of the pipe section. Models are presented for its mechanical failure with respect to stochastic processes of loads and resistance.

Value: The inhomogeneous Poisson point process is used to simulate the formation of new defects, and the Poisson distribution is used to simulate their growth. The first method focuses on the analysis of external corrosion of gas pipelines with metal loss and predicts rupture at a reference pipe segment, constructed with respect to average pipe rupture characteristics from the PHMSA database. The second model predicts reliability for untreated sections subject to external corrosion with metal loss.

Abstract

The foundation is the most significant element of buildings. The foundation structure closely relates to the general construction of the building frame and is largely determined by soil conditions. High-rise buildings are complex engineering structures with increased requirements for strength, stability and durability. Therefore, their safety and durability depend on strength, deformity and stability of foundation. These principles allow creating foundations of the higher quality, bearing capacity, reliability, and durability.

Purpose: Optimization of production processes in the construction of foundation structures of super tall buildings and structures.

Research findings: The structural design of the Lakhta Center 462 m high in Saint-Petersburg, which is the tallest building in Europe. A particular attention is paid to the design and construction of the foundation. Key results can prove operation and design of high-rise buildings designed for weak and unstable soils.

Value: Determination of the most significant factors influencing the choice of production processes during the construction of super-tall buildings.

Abstract

Purpose: The aim of this work is to study the density, thermal conductivity and strength of insulating materials and fine-grained concrete based on cement binder with the use of foamed silicates. Vermiculite from Tatarsky deposit (Krasnoyarsk region), perlite from Khasynsky (Magadan region) and Mukhor-Talinsky (Republic of Buryatia) deposits, and tripoli from Potaninsky deposit (Chelyabinsk region) are used to obtain porous fillers.

Research findings: It was found that the strength of materials based on cement binder and foamed silicates is determined by the strength of hydrated cement, aggregate, and contact zone of hydrated cement and filler. The coefficient of thermal conductivity of insulating materials based on foamed granules of natural dispersed raw materials (vermiculite, perlite, tripoli) with cement (23.5 vol. %) ranges from 0.112 to 0.181 W/(m·deg), which is 1.5–1.6 times higher than thermal conductivity of the granular layer.

Compressive strength of the obtained materials ranges between 2.0 and 4.0 MPa. Compressive strength of lightweight concrete with the silica sand content of 32 vol.% and plasticizer, increases up to 8.5 MPa in compositions with vermiculite and up to 9.4 MPa in compositions with perlite from Mukhor-Talinskoe deposit.

Depending on the quartz sand content, the density of concrete with foamed vermiculite and foamed perlite varies from 1100 to 1400 kg/m3 and from 1300 to 1600 kg/m3, respectively. Thermal conductivity of concretes with minimum density is 0.193 W/(m·deg) in the composition with vermiculite and 0.286 W/(m·deg) in the composition with perlite. At the maximum density of fine-grained concrete, the thermal conductivity increases to 0.277 and 0.411 W/(m·deg), respectively.
