Building Life Cycle

Recent years, many infrastructures, say building structures and bridge structures, have suffered from multi-hazards. According to official reports, 286 fires broke out due to the 2011 off the Pacific coast of Tohoku Earthquake, and fire after 1995 Kobe earthquake destroyed almost 7000 buildings. Current design codes treat earthquakes, fires and explosions as completely independent. The application of multi-hazard design is essential for improving the safety of structures, reducing building life cycle costs and increasing efficiency. In this paper, some influential multi-hazard incidents are described primarily, and the state-of-the-art and research needs on multi-hazard design are presented.

Statement of the problem. One of the relevant scientific and technical issues for improving the state-of-the-art and advanced monitoring methods is alarm construction (including in the minds of ordinary minds) with the emergence of uncompromising objects, and the future of unfinished control. It is quite common that conditions arise when it is not possible to perform a full-fledged monitoring of certain types of deformations of building structures by means of traditional methods. It is required to develop universal, superior and manual methods for the control of different geometric parameters of structures for taking timely measures to ensure the stability and stability of the structure and enabling the transition of the structure in the interconnection of the robotic mill as well. Results. All of the considered methods of statistics of the ways to control the output and have been revised based on the maintenance and repair of the conserved Voronezh nuclear power plant for heat supply.Conclusions. The methods of calculating deformations and the quality of the preparation of alarm constructions for metric photography allowance to carry out repeated monitoring of the technical mill with the necessary accuracy.

Advances in building-integrated photovoltaic (BIPV) systems for residential and commercial purposes are set to minimize overall energy requirements and associated greenhouse gas emissions. The BIPV design considerations entail energy infrastructure, pertinent renewable energy sources, and energy efficiency provisions. In this work, the performance of roof/façade-based BIPV systems and the affecting parameters on cooling/heating loads of buildings are reviewed. Moreover, this work provides an overview of different categories of BIPV, presenting the recent developments and sufficient references, and supporting more successful implementations of BIPV for various globe zones. A number of available technologies decide the best selections, and make easy configuration of the BIPV, avoiding any difficulties, and allowing flexibility of design in order to adapt to local environmental conditions, and are adequate to important considerations, such as building codes, building structures and loads, architectural components, replacement and maintenance, energy resources, and all associated expenditure. The passive and active effects of both air-based and water-based BIPV systems have great effects on the cooling and heating loads and thermal comfort and, hence, on the electricity consumption.

Close Fit

The piping support or restraint design and analysis must meet or exceed requirements of the applicable ASME Codes and standards specified for loading conditions of nuclear power plants such as ASME Boiler and Pressure Vessel Code, Section III, Division 1, Subsection NF. In the piping industry, various restraint types such as shock and energy absorbers, struts, dynamic clamps, etc., are used in the field to provide support between piping and building structures. This work primarily focuses on dynamic clamps, specifically, variations such as traditional 3-bolt dynamic clamps and dynamic yoke clamps. Dynamic yoke clamps have a close fit around the pipe and can be used in more applications than 3-bolt dynamic clamps such as instances of limited space, due to the smaller size of the clamps (distance from center of pipe to center of pin), and connections with larger binding angles. Additionally, finite element analysis is utilized to demonstrate superior performance of the yoke style clamp. Therefore, this study yields results that provide a strong substitute for the 3-bolt clamp. Previously, a 3-bolt clamp was the clamp of choice but the state-of-the-art design of a yoke style clamp makes it a better piping support for the dynamic application.
