In this study, Lead Core Rubber Bearings (LCRB) have been optimized for minimum response quantities by optimizing their mechanical properties under variable pulse-like ground motions, e.g., bearing accelerations and bearing displacements. In order to characterize the general behavior of the base isolation system, random variables have been selected: the isolator period, effective damping ratio, superstructure mass, design displacement, and yield displacement. The shear beam-stick model has been implemented for a single degree seismically-isolated building. Afterward, the dynamic response of the seismic isolation system considering the variability in LCRB and superstructure mass has been investigated. A hysteresis model based on Bouc-Wen is used in the development of the isolation device. The variability of seismic responses has been examined through Monte Carlo simulations (MC). Hence, 37800 time-history analyses were conducted, and the influence of levels of uncertainty of input parameters on seismically isolated buildings' dynamic responses is investigated with 126 natural pulse-like ground motions with pulse periods ranging between 0.6 s and 13 s. Furthermore, the "Desirability Function Optimization" (DFO) method was used to determine the best compound properties of LCRB parameters. Lastly, the LCRB behavior has been optimized as a result of considering uncertainties in the parameters of natural excitation, thereby reducing the response criteria.

Microbiologically induced calcite precipitation (MICP) is a technique that comes under a broader category of science called biomineralization. It is a process by which living organisms form inorganic solids. Bacillus Pasteruii, a common soil bacterium can induce the precipitation of calcite. MICP is highly desirable because the calcite precipitation induced as a result of microbial activities, is pollution free and natural. A durability of control or treated cement mortar by bacterial cells against 5% magnesium sulfate, for one year, was studied. In this study the cement mortar mixed with one optical density (1.0 OD) of bacterial cells. Microbial calcite precipitation in cement mortar was visualized by SEM. Also, Ettrengite phase which formed in cement mortar matrix was identified by DTA analysis and visualized by SEM techniques. study demonstrated that the microbial induced calcite precipitation resulted in an increased resistance of mortar specimens, and sulfate penetration. The cement mortar mixed with bacterial cells was more durable than that of control sample against magnesium sulfate solution. calcite precipitated by bacterial cells filled the open pores of mortar which leads to decrease penetration or water absorption and, therefore, increase the compressive strength.

Boundaries between art and architecture are becoming more and more blurred. In the field of art, site-specific and site-responsive artworks appear as a form of critical spatial practices, while on the other hand, art provides architects experimental freedom to explore the potentials of space. Regarding the rapidly changing conditions of the contemporary world, issues of critical thinking and innovative design in architecture are significant more than ever before. And three-dimensional site-specific works of art seem to provide an experimental arena for challenging conventional and consolidated design strategies. It is apparent that also in architectural education, questioning the existing solutions and exploring original paths of thought become crucial skills for students to be gained through their design studios. Creativity and critical thinking are intended to be introduced throughout the first year of architectural school. This study aims to discuss the possibility of using site-specific artworks as a methodology for the first-year design studio in architectural education. Based on the process and outcomes of an experimental course, structured as a paradigm shift in basic design studio by focusing on the architectural space from the very beginning of the semester, the process and the outcomes of the course will be evaluated regarding the issues of spatial perception, critical and conceptual thinking, and multisensory experience of space.

The bibliographic review proposal is to present diversity under the concept of habitability, taking up the authors David Harvey, Henri Lefebvre, Moreno and Salvador Rueda for the development of popular housing. In this sense, it has presented the phenomenon of land use zoning, generating conflicts in living conditions, compromising the search for a better habitat for the communities. In the search for the need to reduce the indicator of the housing deficit, it has led to the tendency to build housing in "mass" or in large volumes, these structures of imposed basic design, repetitive and without any consideration of the sociocultural characteristics, which allow the appropriation of the new inhabitants, who come to transform the building according to their needs; Redirecting the objective of territorial planning to solve physical, production and economic aspects of urbanism. In this sense, with the passage of time the standards are more rigorous for the control of builders and urban development, but a minimum content of habitability. Thus, the identification of the characteristics of diversity in popular housing with the criterion of habitability from the theory, which allows understanding and raising a critique of the causes, effects and current problems from the use of the zoning methodology. in the territory and the communities that inhabit it.

Housing policies have raised a before and after in the development of the territory. As of 1991, with the Constitutional reform, the regulations redirect the physical, production and economic behaviors of urbanism; In this sense, with the passage of time, the regulations are more rigorous for the control of builders and urban planners, disassociating themselves from the elements with habitability content. A concept that compromises the search for a better habitat from a holistic physical-spatial perspective for housing from urban planning, which from the normative change the implementation has taken quantitative alternatives to respond to indicators of efficiency and not with effectiveness, ceasing to act to respond to the real needs of individuals and communities. Popular housing is one of the elements that has had negative effects, in which self-construction ceased to be present in the construction of the city before the imposition of others, which in the research work focuses on the analysis of housing policy under the concept of urban habitability in the development of the territory for the vulnerable population, taking up essential elements proposed by the authors David Harvey, Henri Lefebvre and Salvador Rueda. Thus, the bibliographic review on housing policies in Colombia allows us to understand the causes and effects the territory has had since its implementation and, on the other hand, the generation of a contrast between the before and after around this aspect in territorial developments. from habitability.

Deconstructing a building with the help of drones and BIM (building information modelling) is becoming increasingly common as a more efficient, eco-friendly, and affordable alternative to the traditional techniques of building disassembly. This paper presents a systematic review following the methodology of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to investigate the role of drone technology and BIM in building deconstruction. A total of 10 studies were identified based on the integration of drone technology with BIM, all of which proved promising in enhancing the process of building deconstruction. The analysis of the 35 and 3 non-academic selected data reveals several key findings. Firstly, BIM is not commonly used in deconstruction or demolition processes, particularly in managing fixtures and fittings of buildings. Secondly, the adoption of deconstruction-oriented design methods and the use of drone technology can significantly reduce the negative environmental impacts of building demolition waste. Lastly, the limited implementation of design for deconstruction practices in the construction industry hinders the realisation of environmental, social, and economic benefits associated with this approach. Overall, this systematic review highlights the potential of drone technology and BIM in improving building deconstruction practices, while also identifying knowledge gaps and areas for further research and development on this topic.
