TL;DR: In this paper, an extensive review on the development of sustainability practices in structural engineering is presented using the systematic review approach, the historical development, application, and advancements of sustainability concepts and practices are presented.
Abstract: This paper reports an extensive review on the development of sustainability practices in structural engineering. Using the systematic review approach, the historical development, application, and advancements of sustainability concepts and practices in structural engineering are presented. Reviews are conducted in terms of structural design, construction materials, and sustainability assessment tools with regard to the triple bottom line aspect of sustainability and multi-hazard resilience. All three factors are summed up, and future avenues are discussed in the paper. The findings highlight that more integrated approaches are needed in the future to assure sustainability practices in structural engineering. Furthermore, it is concluded that the endorsement of sustainability approaches in structural engineering would be a pertinent solution for the changing landscape of structural engineering amidst the multi-hazard challenges.

TL;DR: In this paper , the authors present an analysis of the origin of extensive risks (high-frequency-low-magnitude hazards occurrences) and intensive risks (lowfrequency-high-high magnitude hazard occurrences) in Central America from 1990 to 2015 using the disaster databases EM-DAT and DesInventar.
Abstract: Abstract Central America is affected by geological and hydrometeorological hazards that, together with its high exposure and vulnerability, comprise risky scenarios for disasters. This region presents a significant number of casualties and economic losses due to disasters every year. We present an analysis of the origin of extensive risks (high-frequency-low-magnitude hazards occurrences) and intensive (low-frequency-high magnitude hazard occurrences) in Central America from 1990 to 2015 using the disaster databases EM-DAT and DesInventar. Findings reveal that Costa Rica reported the greatest number of both intensive and extensive risks (disaster occurrences) whereas El Salvador, Guatemala, and Honduras experienced the highest number of casualties in terms of injuries and lost, as well as highest number of damaged or destroyed houses by extensive and intensive risks. Disaster databases, like the ones employed in this research, provide useful data for risk assessment, land use planning, and risk management in developing countries. This study stresses the need for exhaustive risk assessment at the local, regional, and national scales.

TL;DR: In this article , the authors developed schematics and evaluated the performance of hybrid mesh turbomachines at the patenting stage of individual technical solutions, based on simulations using computational fluid dynamics (CFD) and additive technologies.
Abstract: This paper develops schematics and evaluates the performance of hybrid mesh turbomachinery at the patenting stage of individual technical solutions. This type of turbomachine uses reduced-sized blades and also forms flow channels with a mesh structure between the blades. The research methods are based on simulations using computational fluid dynamics (CFD) and additive technologies. An intermediate conclusion is that a new scientific direction for investigating and creating hybrid mesh turbomachinery equipped with mesh jet control systems was formed to develop Euler's ideas. This paper describes new possibilities for the simultaneous implementation of two workflows in a single impeller: 1) Turbine workflow, and 2) Compressor workflow. Calculation methods showed possible improvements in the performance of the new turbomachines. This paper considers options for mesh turbomachine operation in the two-stage gas generator mode with partial involvement of atmospheric air in the workflow. Preliminary calculations based on examples show that it is possible to expect a two- to four-times increase in thrust when using hybrid mesh turbomachines. Ongoing studies mainly focus on developing multi-mode turbomachinery that works in complicated conditions, such as offshore oil and gas fields, but some research results are applicable in other industries, for example, in developing hybrid propulsion systems or propulsors.

TL;DR: In this article, the authors report the construction technology of traditional wattle and daub houses in Bhutan and perform sustainability analysis, and the conventional sustainability assessment framework is modified with three additional parameters.
Abstract: The modern construction technologies mostly dependent on nonrenewable resources so impose grave challenge to the environment; thus, widespread concern can be found in terms of sustainability of modern construction materials. Earth technology is the ideal tool to tackle the global crisis of environmental degradation; however, such constructions are limited worldwide. Unlike other countries, Bhutan has a considerable fraction of wattle and daub houses. This study reports the construction technology of traditional wattle and daub houses in Bhutan and performs sustainability analysis. The conventional sustainability assessment framework is modified with three additional parameters. Furthermore, sustainability of brick and stone masonry constructions is compared with wattle and daub systems. The sum of findings highlights that wattle and daub houses are more sustainable solutions than other dominant structural forms in Bhutan.

TL;DR: In this article , a systematic literature review is conducted addressing three relevant questions: What type of mass damper is preferable by the associated industry? How are mass dampers distributed around the world? Is industry following research?
Abstract: In this paper, a state-of-the-art literature review is presented emphasising on the development of control variants for mass damper schemes on building-like structures. Additionally, a systematic literature review is conducted addressing three relevant questions: What type of mass damper is preferable by the associated industry? How are mass dampers distributed around the world? Is industry following research? Through the systematic literature review, updated lists of mass damper implementations and control algorithm applications in real-life structures were compiled. 208 case-studies are discussed in total. It is found that, 63% of them refer to passive tuned mass dampers, 31% to hybrid mass dampers, 4.0% to active mass dampers and only 2% to semi-active mass dampers. Regarding control algorithms, controllers of 24 structures driving semi-active, active or hybrid mass dampers are presented. It is concluded that the industry considerably lags behind latest structural control research both regarding implementations and overall management.

TL;DR: In this article, the disaster resilience of place (DROP) model is proposed to improve comparative assessments of disaster resilience at the local or community level, and a candidate set of variables for implementing the model are also presented as a first step towards its implementation.
Abstract: There is considerable research interest on the meaning and measurement of resilience from a variety of research perspectives including those from the hazards/disasters and global change communities. The identification of standards and metrics for measuring disaster resilience is one of the challenges faced by local, state, and federal agencies, especially in the United States. This paper provides a new framework, the disaster resilience of place (DROP) model, designed to improve comparative assessments of disaster resilience at the local or community level. A candidate set of variables for implementing the model are also presented as a first step towards its implementation.
