The booming growth of computational abilities in the 21st century has led to its assimilation and benefit in all horizons of engineering. For civil engineers, these advancements have led to groundbreaking technologies such as BIM, automation, and optimization. Unfortunately, even in an era of dwindling resources and dire need for sustainability, optimization has failed to attract implementation in practice. Despite an exponential growth as an area of research interest, the optimization of engineering structures such as reinforced concrete (RC) is still a complex task that requires multidisciplinary knowledge, hindering its practicability. Although past review papers have delved into this topic, they have only been able to cover the breadth of information available by covering broader aspects of optimization of structures. This study on the other hand aims to cover this topic in depth to uncover problem specific trends and issues, by focusing only on optimization of RC cantilever retaining walls. Although there is an abundance of research studies on this topic, there is an absence of any critical review to tie them up, and concurrently with its broader scope, it suffers the same lack of applicability in the field. The in-depth review presents a summarization of all the online publications including research articles, conference papers, and theses to the best of authors’ knowledge on the topic of RC cantilever retaining wall optimization. Geographical trends, regional developments, and prominent journals have been identified. The design codes, problem formulation, objectives, constraints, variables, and their optimization techniques are tabulated for ease of understanding. Unique areas of development investigated by the different researchers have been highlighted. Lastly, comprehensive recommendations for future works have been detailed with a focus on improving its applicability and assimilation into the construction industry.

“…Despite all these challenges many researchers have tried to find cost optimize designs of RC building components. Milajić et al [1] reviewed various methods available in literatures for optimal design of reinforced concrete structure. They focused on the problems of these existing methodologies, such as: gap between the theory and practice in the field, lack of universal criteria and standard benchmark problem etc.Also, when ones talks about of cost optimized design of a complete RC building project, it includes optimizing the topology of the building, material costs of the building components, reinforcement distribution, cost of shuttering, labor cost maintaining all the safety guidelines of competent authority.…”

Present paper deals with the cost effective design of reinforced concrete building frame employing unified particle swarm optimization (UPSO). Two building frames with G + 8 stories and G + 10 stories have been adopted to demonstrate the effectiveness of the present algorithm. Effect of seismic loads and wind load have been considered as per Indian Standard (IS) 1893 (Part-I) and IS 875 (Part-III) respectively. Analysis of the frames has been carried out in STAAD Pro software. The design loads for all the beams and columns obtained from STAAD Pro have been given as input of the optimization algorithm. Next, cost optimization of all beams and columns have been carried out in MATLAB environment using UPSO, considering the safety and serviceability criteria mentioned in IS 456. Cost of formwork, concrete and reinforcement have been considered to calculate the total cost. Reinforcement of beams and columns has been calculated with consideration for curtailment and feasibility of laying the reinforcement bars during actual construction. The numerical analysis ensures the accuracy of the developed algorithm in providing the cost optimized design of RC building frames considering safety, serviceability and constructional feasibilities.Further, Monte Carlo simulations performed on the numerical results, proved the consistency and robustness of the developed algorithm. Thus, the present algorithm is capable of giving a cost effective design of RC building frame, which can be adopted directly in construction site without making any changes.

“…So in some areas of construction there are no universal criteria and strict standard benchmarks, such as the case of the optimal design of steel structures [7]. Since there are no regulations that strictly govern the accuracy of the digitized points (regulations relating to the surface), but from the aspect of practical use content cadastre and mapping accuracy of the details on analogue plans, as well as a certain confidence interval (based on probable errors E95), the authors this study classified the mistakes into four groups: …”

SUMMARYIn this study, for the purpose of determining the quality of a digital cadastral plan lines, we made production of digital lines plan, vectoring, and the diameter of the original data and maintaining the diameter of the five types of lines. Since digital utility cadastre plan is the basis for making part of the database of the cadastre lines, but that lately often resorted vectorization of analogue lines plans, or "digitization on the screen" in this study we analyzed the accuracy and reliability of digital geodetic plan lines created vectoring analogue plan. There we also made individual and comparative analysis of digitized content, according to the type of lines, on the basis of which it was concluded that the overall quality of the digital plan lines obtained vectoring pretty good that can meet the needs of most users of the cadastre lines. The conclusions drawn in this article can serve amendments and harmonization of existing geodetic and cadastral regulations with the regulations related to the business owners lines, regulations governing zoning and help define the strategy and development directions records of public infrastructure.
