The crack formation as a typical damage phenomenon in the reinforced concrete structures can not be avoided. The structural engineer in the practice however gives efforts to limit the width of cracks according to design standards. The cracking behavior in a reinforced concrete member with normal strength of concrete may have been sufficiently investigated and design standards, e.g. ACI-Building Code, CEB-FIP MC90, suggest some formulas to determine the crack behavior e.g. crack space, crack width, transfer length, tension stiffening effect. However, there is no limit to the use of these formulas regarding the concrete strength. The purpose of this paper is to review the prediction formulas for tension cracking behavior suggested in design standards for the high strength of concrete. A numerical model in a crack element with a given length will be formulated in which the cracking behavior can be investigated in detail. Results from the numerical analysis will be compared with them of experiments.

Today it proved that environmental matters such as global warming, atmosphere pollution, acid rain were resulted from consumption of energy using fossil fuels. But Domestic construction work to consume more than the of total fossil fuels quantity is not ready to consider a measure quarter about those matters. This study analyzed LCA through calculating quantity of construction materials following remodeling of apartment, energy consumption and CO₂ discharge. We found that step of maintenance and repair is charge most of environmental loads. Thus environmental loads could be diminished through controling of these steps.

Purpose: In this study, we examine the application cases of RPA(Robotic Process Automation) and its technology and examine its effects. When a company wants to introduce RPA, it aims to present a plan that can be introduced to meet the purpose of RPA introduction and needs. Methods: We explored RPA and AI(Artificial Intelligence) technologies, which were the background of the research, and derived cases related to RPA through review of research literature and related data of UiPath. Results: RPA is applied mainly for simple repetitive rule-based tasks, but as AI technology evolves, tasks for applying RPA are expanding. Increasingly, companies are applying RPA in conjunction with OCR and chatbots, and some solutions are attempting breakthrough methods to connect AI technologies applied to customers (AI Fabric, UiPath). Conclusion: Enterprise RPA adopters need to be fully prepared for office automation in conjunction with AI. Please contact me for further information and help. I hope my paper will be helpful to corporate managers considering RPA adoption.

However, there is no limit to the use of these formulas regarding the concrete strength. The purpose of this paper is to review the prediction formulas for tension cracking behavior suggested in design standards for the concrete including higher strength concrete. A numerical model in a crack element with a given length will be formulated in which the cracking behavior can be investigated in detail. Results from the numerical analysis will be compared with them of experiments.
