Prior research has highlighted distinctions in the confinement mechanism for concrete-filled double-skin steel tube (CFDSST) columns with octagonal sections compared to circular and square sections. Current design codes primarily address the models for the design of square and circular sections in columns made of concrete-filled steel tube (CFST)....

Concrete corbels are short cantilevers subjected to monotonic and repeated loads. Repeated loads generally negatively affect the concrete structural members' strength as they decrease the resistance to external loads. To increase these loads, strengthening with carbon fiber reinforced polymer (CFRP) strips as an externally bounded technique is used...

Due to the rapid growth of the building sector, a tremendous amount of waste is generated, which has become an alarming issue for every country. Therefore, there is a substantial need to implement a sustainable way to minimize the construction solid waste (CSW), generated through the construction activities. Construction solid waste management (CSW...

The presence of the openings negatively effects on the strength of the beams where they act as a weak point because of the sudden change in the cross-section of the beam, so it becomes necessary to make strengthening for the beams to resist the effect of the openings and improve the strength of the beams, especially if the beams are subjected to re...

In a number of third-world nations, municipal solid waste (MSW) is deposited on the ground without treatment. The accumulation of heavy metals in the surrounding environment is one of the greatest difficulties, and there is evidence that the toxic substances included in MSW can produce a variety of adverse consequences in humans. At the landfill in...

Waste generation in smart cities is a critical issue, and the interim steps towards its management were not that effective. But at present, the challenge of meeting recycling requirements due to the practical difficulty involved in waste sorting decelerates smart city CE vision. In this paper, a digital model that automatically sorts the generated...

Mangrove offers a unique and functional characteristic that proves to be beneficial to its surrounding ecosystem. It also benefited the local communities positively in the socio-economic growth via the increase in ecotourism product varieties. Ecotourism activities must not further deteriorate, but, be able to protect and preserve the mangrove ecos...

The bond strength between the steel fiber and the ultra-high performance concrete (UHPC) matrix plays a significant role in improving the behavior of plain UHPC. This paper compiles the existing experimental research database on the pullout bond performance of steel fibers embedded in UHPC. The variations of key parameters in the database are...

Octagonal concrete-filled double-skin steel tube (OCFDST) columns have drawn the attention of academia and building industries since they combined the advances of higher confinement of circular CFDST columns and the better constructability options of square CFDST columns. Therefore, this paper investigates numerically the behavior of axially compre...

Staff, visitors, and patients are extremely likely to suffer from stress in healthcare environments. Through natural environments like hospital gardens, high stress levels can be significantly neutralised to improve health and boost healing. First, this study is aimed at evaluating the perceived curative features of hospital gardens for prospective...

The significance of the construction industry is special as it may lead to cost savings and economical development of countries around the world regardless of its status; underdeveloped, developing or developed. However, there are various restrictions and risks to the execution of a construction project that restrict its start or progression operat...

Hotel guests' comfort and satisfaction of perceived Indoor Environmental Quality (IEQ) in former certified green hotels is crucial for both IEQ body of knowledge and the green hotel management for future improvements. The methodology used for this study is text mining of online hotel guest reviews for the time period within the GBI certification va...

The tourism and hotel industry positively contribute to the country's socioeconomic sector, however, it simultaneously impacts surrounding nature into further deterioration. There has been green building and green hotel rating tools emerging worldwide in the attempt to operate sustainably with better performance, as well as ensuring human comfort i...

Indoor Environmental Quality (IEQ) refers to a building's indoor environment performance. This review highlighted Indoor Environmental Quality (IEQ) in buildings and how it impacted its inhabitants' health, wellbeing and satisfaction. The paper will touch on basic understanding and general terms pertaining to Indoor Environmental Quality (IEQ). It...

Abstract--- Malaysia tourism and hotel industry has proven its socio-economic benefits by placing at the third highest in contributing towards the country’s foreign income contributor. However, the increase of tourism and the hotel industry pose an impact to nature if not properly managed. This review highlights the statistics of tourist arrival, t...

Abdulhasan et al.: Combining GIS, fuzzy logic, and AHP models for solid waste disposal site selection in Nasiriyah, Iraq-6701-APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 17(3): 6701-6722. Abstract. Finding locations suitable for disposal of solid waste is one of the fundamental challenges facing municipal cities and environmental stability. The pres...
