Micro mechanism consideration is critical for gaining a thorough understanding of amorphous shear band behavior in magnetorheological (MR) solids, particularly those with viscoelastic matrices. Heretofore, the characteristics of shear bands in terms of formation, physical evolution, and response to stress distribution at the localized region have gone largely unnoticed and unexplored. Notwithstanding these limitations, atomic force microscopy (AFM) has been used to explore the nature of shear band deformation in MR materials during stress relaxation. Stress relaxation at a constant low strain of 0.01% and an oscillatory shear of defined test duration played a major role in the creation of the shear band. In this analysis, the localized area of the study defined shear bands as varying in size and dominantly deformed in the matrix with no evidence of inhibition by embedded carbonyl iron particles (CIPs). The association between the shear band and the adjacent zone was further studied using in-phase imaging of AFM tapping mode and demonstrated the presence of localized affected zone around the shear band. Taken together, the results provide important insights into the proposed shear band deformation zone (SBDZ). This study sheds a contemporary light on the contentious issue of amorphous shear band deformation behavior and makes several contributions to the current literature.
As an emerging country, the construction industry is one of the factors to the development growth of the national economy. In Malaysia, there are various types of construction projects such as office buildings, housing, houses of worship, public and private institutions as well as the construction of infrastructure such as roads, drainage, landscaping and so on. The development is considered as an asset that must be protected in order to maintain the function of the development. Moreover, to emphasis on good asset management can reduce high operating costs and has helped many companies to improve efficiently in the face of recession. In addition, maintenance costs can be improved by taking into account, the condition of the building and report on the performance of building maintenance costs before a decision is made. Development of a wide range of defects is not a new scenario in Malaysia. Whether new or old, each is exposed to different types of defects. This paper is to discuss the common maintenance problems and building defects on civil and structural elements at the floating mosques buildings across Malaysia due to various factors. It will also provide opportunities to improve understanding of the building surveying profession in our country, namely to understand the scope and work as a building surveyor.
Although a considerable amount of research has been focused on how building information modeling (BIM) helps improve sustainable construction, BIM(6D) model validation and efficient data analysis methods are still lacking. This study aims to provide the more effective research method and analytical method. The Greenjiansville Sunshine analysis software Sun2020 and daylight analysis software Dali2020 were used for 6D modeling and simulation and real simulation of a building outside the daylight range and time. The daylight coefficients, outdoor visual field observation rate, and daylight quality were calculated for the rooms inside the building. The results show that single the daylight statistics and analysis color map can not accurately analyze whether the actual daylighting meets the demand, but combined with Power BI comprehensive analysis can get fast and accurate results. This paper provides important guidance for building researchers and practitioners to better align BIM development with green building development in the future.
Building Information Modelling (BIM) represents an approach that aims to form and manage information over the building’s whole life cycle. BIM has been mainly adopted for commercial or large scales building projects while being mostly neglected by small or residential building. Therefore, the objectives of this study are to evaluate the readiness of BIM implementation for housing maintenance in Sabah, to access the types of priority maintenance in house maintenance, and to determine the potential benefits to apply BIM for housing maintenance. This research is focused on the participants of the construction industry in Sabah to obtain their opinions towards the opportunities and strategy of Building Information Modeling (BIM) adoption in housing maintenance. Two method was done which was a pilot survey that was analyse using SPSS and Revit modelling. The result shows that most of the industry sectors had a moderate knowledge about BIM but they agree that it should be implemented by the authority and the percentage of willingness to change from the conventional maintenance to BIM was high. The 3 highest ranked of priority maintenance is the pipes linkage, electrical faults and sanitary appliance failure. Furthermore, a modeling is created using Revit application and access of information which called the Level of Detail (LOD) regarding the items in houses is easily obtain using schedule list for the purpose of maintenance.
