This study aims to investigate basic requirements for adopting the Building Information Modeling(BIM) technology to management of civil infrastructures. The state of the art on BIM guidelines developed major countries was investigated, and a common framework of the guideline contents was built in order to categorize the requirements. In addition, it was investigated that the point of view on the facility management in the BIM guidelines showed different from the traditional civil infrastructure domain. On the basis of the investigation results, this paper proposed the core requirements categorized into three respects: development of application models, standardization, modification of regulations.

With regard to steel construction, many studies have been performed to examine the structural behavior of the bolted connections domestically and in other countries. Especially, a domestic study was conducted on the block shear fracture and shear lag effect on the single-bolted angle connection in carbon steel. In this study, specimens were prepared with the end distance parallel to the loading direction and bolt arrangement ($1{\times}1$, $1{\times}2$), as the main variables. Then the fracture mode and the curling effect on the bolted angle connection in austenitic stainless steel were investigated. Moreover, the fracture mode and ultimate strength were compared, and the strength reduction by curling was estimated.

The purpose of this study is to evaluate the stiffness of the mechanical sleeve reinforcement splices filling high-strength mortar under monotonic loading. For this objective, we analyzed and compared the previous test data of 189 actual-sized mortar-filled sleeve bar splices specimens, including the reinforcing bar splices prepared and tested by the author. The paper results indicated that the minimum values of compressive strength of mortar($f_g$) multiplied by the ratio of reinforcement development length to bar diameter(L/d) were suggested for holding the stiffness of the mortar-filled sleeve reinforcement splices required in AIJ code.

Purpose: Facilities for infection prevention according to the characteristics of the patients, caregivers and medical personnel are needed in the patient triage room of the emergency department as a space for the first medical examination and classification of the patients. This study focus on the patient tirage room with the highest frequency of use in the emergency department to prevent the hospital acquired infection of the emergency department. Methods:: This study analyzed the facilities standard needed for the infection prevention through interviews with the medical personnel and analyses on the facilities standard/cases of foreign hospitals and facilities standard at home and abroad Results: And based on this, it attempted to present improvement measures by analyzing the line of circulation and space used by infected patients in a hospital designated in the regional emergency medical center among hospitals whose emergency department overcrowding index is high. Implications: The facilities standard for the infection prevention among the courses for patient classification of the emergency medical centers could be identified and implemented to prevent infection.

A large number of accidents at an underground place have been happening, including the gas explosion under construction of subway, the fires of underground utility and underground shopping malls, and other explosion, at home and abroad recently. These accidents make the function of a city ineffective due to the paralyses of electricity and communications net as well as the loss of property, and cause people to feel unsecured with accompaniment of a heavy of toll of lives. This study suggests safety assessment items and fire protection assessment technique for underground shopping malls by extracting dangerous elements in the management stage through examination of related accidents, documents and present conditions.

Recently, the system that can eliminate discrimination and barrier to disabled, ensure the substantial independence of disabled and help participation in community of disabled is required. Therefore, the purpose of this study is 'construction of the Barrier-free environment' which members of societies included the disabled can live safely in the daily living environment. To achieve this result, this study is shown establishment and complementary direction of the policy related convenient facilities by comparing between domestic and international policy of the convenient facilities. The results of this study are as follows; Firstly, among the conflicting part between related laws and design standards shold be constantly supplemented. Secondly, policy to promote convenient in residential part is needed. Thirdly, composition of the organization that can support professional housing reconstruction is required. Fourthly, from early stage of policy making, not only opinion reflection of users but also maintenance of convenient facilities, continuous maintenance plan and making a policy for verification system is needed. Finally, when the revision of the existing policies or new policies undergo, 'Barrier-free perspective' should be considered.

A stud connector was used by the shear connector of a composite beam. The shear connector is an important element in heightening the composition rate of a composite beam .study was based on the experiments conducted on 15 specimens using the push-out test.In this paper, through an experiment, the shear connector of other forms was analyzed instead of the stud connector. It is hoped that this application can be used in composite beams.

Purpose: The purpose of this study is to analyze the deployment characteristics of korean and foreign mobile hospitals and to draw out the advantages and disadvantages based on the movement of patients. Methods: The arrangement and user movement lines of foreign mobile hospitals which were actually utilized, and the arrangements and user movement lines of korean mobile hospitals are compared and analyzed. Based on the results of the comparative analysis, we suggest the optimal placement of mobile hospital in Korea. Results: The recently developed Korean mobile hospitals have made many improvements. However, there is no practical use case for the mobile hospital in Korea, so it is necessary to establish the basis for the mobile hospital development site and the site access considerations. In addition, there is no detailed analysis of the movement of the administrators other than the medical staff, and it is considered that research on safe waste disposal is further needed. Implications: It is highly likely to be used as a basic data to find out the combination method of mobile hospitals that can efficiently deal with disasters through the arrangement and movement analysis of mobile hospitals in Korea and abroad.

Purpose: This study aims to propose a framework for climate change risk management by analyzing characteristics of climate-induced disasters. Method: The recent global and domestic trends of loss and damage under natural disaster events and the characteristics of climate-induced disasters were analyzed to design a framework for climate change risk management. Results: In consideration of the uncertainty of climate risk and various spatio-temporal scales of climate disasters, a new framework is suggested for comprehensive climate risk management that includes risk assessment, goal setting, planning, monitoring and evaluation, learning and adjustment. The framework aims at an iterative process that is activated by stakeholder engagement. Conclusion: Pilot studies need to be conducted to revise and polish the framework in the future, and institutional arrangements should be prepared for the effective implementation of the comprehensive climate risk management.

The main problem with roads is that cracks and settlement occur over time due to loads acting from the surface layer. One way to solve this problem is to use Geocell. Geocell can be used for structural reinforcement for erosion prevention, ground stabilization on flat and steep slopes, load bearing, and ground preservation. In this study, analyzed road pavement application cases using Geocell and purpose of this study is to analyze the bearing capacity of a road paving method including Geocell using field tests and LFWD(Light Falling Weight Deflectometer) equipment. In addition, the bearing capacity was compared and analyzed with the existing traditional road pavement method.
