The deteriorated PSC Beam bridge is necessary improved reinforcement method. In the study, it is proposed the box reinforcing method which could make the stiffness of the PSC Beam bridges increase more stably through the secondary composition effect of open type PSC Beam bridge's girder which is converted into the consolidation box type and the half panel is formed between the lower flange of the PSC Beam about the deteriorated PSC Beam bridge suffering the capacity decline. In case the proposed reinforcement method combine with the existed external prestressed method, the close analysis depending on the time is conducted by the construction stage because of searching the effect of reinforcement quantitatively. The reinforcement method of the box type which is proposed an efficiency improvement in objective in application case, by a reinforcement method after proposing the whole and bend sectional reinforcement method, against a each reinforcement method evaluated the upward camber which it follows in secondary composite effect and a member stress characteristics. Also, the structural safety of PSC Beam bridge is evaluated quantitatively by examining of rating factor through load carrying capacity evaluation.

This study reviewed the existing legal framework governing construction supervision practices and conducted a survey of expert groups to identify and propose strategies for facilitating the digital transformation of construction supervision processes, with the goal of enhancing the quality and safety of construction projects. The research underscored the necessity for digital transformation to improve quality, safety, and efficiency of construction supervision. Additionally, it highlighted the need for greater consistency and clarity in terminology related to construction supervision. The study also presented recommendations for improvement, which included: establishing a structured supervision checklist to ensure safety and compliance, establishing a specialized construction supervision corporations subject to qualification screening, and introducing evaluation criteria to encourage the adoption of digital transformation technologies in construction supervision. The findings of this study are intended to serve as the foundation for future policy and regulatory frameworks aimed at promoting the digital transformation of construction supervision practices.

According to the trend of tail building, it is essential to improve productivity in tall building construction. However, the study on that is insufficient until now. Therefore, the purpose of this study is to propose a new work process of efficient concrete structural fame work to improve productivity in tall building construction. The results of being applied proposed work process are that the 5day cycle time of concrete structural frame work is cut by 0.5day and the quantity of rebar to be demanded in concrete structural frame work is reduced.

The purpose of this study is to enhance durability of solidifying mat. solidifying mat excellent mechanical properties of geotextile. multi-layer coating system is applied to the mat and the chloride ions penetration resistance, chemical resistance, accelerated carbonation test were evaluated by testing the durability. Durability test results are as follows. chloride ions penetration resistance results are coated mat is approximately 70 % lower than plain. chemical resistance test results are coated mat no discoloration. accelerated carbonation test results are coated mat is approximately 90 % lower than the plain.

Aesthetic design guidelines of bridges were developed in many countries. As iconic structures, bridges need to be attractive and durable as they serve many generations. In this paper, a new design process of concrete structures considering 3D shapes and texture was proposed. The 3D design needs to consider function, economy, advanced technology, tradition and local culture. 3D printers enable the combination of artistic design and engineering design for concrete structures. Parametric modeling with iconic design was utilized to produce 3D formworks. As a pilot project, a railway bridge girder was designed and the proposed technologies were applied. Detail requirements to improve constructability and quality of concrete surfaces were derived. From the pilot applications, design guidelines were suggested.

최근 설계, 시공되는 건축물은 초고층 또는 대단지 주거시설로서 화재발생시 초기에 빠른 대응이 요구 되나 근무자의 첨단 소방시설관리에 대한 지식은 부족한 실정이다. 본 연구에서는 건축물의 대형화로 인한 네트워크제어방식의 효용성을 알아보고 기시공된 현장의 화재수신기 네트워크 운영 실태 및 현황을 파악 하여 관리에 일조하고자 한다. 이를 위해 10개 대형현장의 네트워크를 조사한 결과 경보시스템에 대한 낮은 신뢰도 때문에 타설비와의 시트템구축을 기피하고 있었다. 또한 방재관련 법규의 제한된 규정으로 인한 통신선 사용에 있어서의 문제점도 개선될 필요가 있었다. 아울러 관리자의 잦은 이직으로 인한 기술적 축적 방안 마련, 복지문제와 면적이 넓은 네트워크시스템에 대한 신호처리방법 및 반응시간등에 대한 규정제정이나 운영상 표준화가 필요하였다.

Although the introduction of new materials and new construction methods and overseas materials has become more active due to the diversification of the construction market, the quality standards of waterproofing methods in Korea are insufficient. In particular, the quality control standard is applied to the KS F 2622:08 (Membrane Waterproofing layer performance test method), which is the existing standard, to prepare standards for quality control of waterproof materials, which is increased in Korea.

Recently, there has been constituted the government regulations and the normative methods to control the safety management activities in construction fields, but almost of these regulations are ineffective, because of some characteristics safety management have. The needs of the times make government regulations and the normative methods change to autonomic management methods. In this context, it is significant certainly to improve the standard of safety management that is used as a tool to protect the workers from the accidents or industrial disasters in the construction field. In this research, it will be showed that the outside regulations and safety management systems of the head office have their limits to reflect the safety managements of field participants. Then, it will be presented the improved model of self-control safety management activities which is essential for success safety management.

The intention of this study is to analyze safety consciousness of construction labors in Gawang-Ju region. According to Korea Occupational Safety & Health Agency, the rate of disaster in construction industry is very high comparing with other fields. Most of all, the consciousness of construction labors is very important because accidents are caused from it mainly. For this reason, it is necessary to recognize safety consciousness of labors who directly work in construction field. For decreasing the rate of disaster in construction, I examined and analyzed safety consciousness of construction labors and then, groped improvement of safety activity. Finally, this study deducted improvement of safety activities and management.
