As buildings become taller and more complex, the number of high-rise and underground complex buildings is increasing, but risks are also increasing due to the limitations of existing evacuation safety methods. Through this study, we will analyze the fire and evacuation characteristics of high-rise and underground complex buildings, identify problems with the current evacuation safety method, and seek ways to improve them using digital technologies

The main purpose of this study is to establish the reliable method for evaluating fire damage of reinforced concrete building, by using the rational procedure, and to develope the rehabilitation methods of fire damaged concrete structures. Especially, this proposed evaluation method is applied to the fire damaged concrete buildings of domestic, and the rehabilitation methods on the basis of these applied results are proposed and those example are shown. The proposed rational evaluation method for fire damaged concrete building proceeds is estimating the reduction of the mechanical properties of concrete of fire damaged structural members in comparison with the experimental results which are obtained from the compression tests of heated concrete specimens under various temperatures.

This study aims to evaluate how efficiently time-worn building could be managed by using GPS-based video-logging systems. The digitally georeferencing video data taken by a hand-hold GPS-based video-logging system allows quick retrieval and effective management for the complicate and various superannuated building in urban area. The results of the study are as follows. Georeferencing data are possible to trace observed positions by using GPS linked with video and to provide building crack information anytime that could be used to inspect and analyze the safety hazard diagnosis of buildings. Building crack information were measured by the proposed method that is merged with feature tracking and image mosaic of sequenced images. From the study, it reveals that the georeferencing video technique provides more realistic and reliable information in safety diagnosis and it can also be used as the essential and modern tool in urban building management.

According to the actual situation of a university, the emergency evacuation simulation is modeled based on the physical sign, evacuation speed and personnel ratio using the pathfinder software.The experimental construction export utilization rate is compared with the preliminary simulation scenario. The simulation results show that the utilization rate of evacuation stairs and evacuation exits is significantly improved.The optimized solution can provide the most effective evacuation passage, and the research results can provide the basis for the rational planning and management of evacuation passage in university experiment building.

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.

The gang-form widely used in apartment construction sites has advantages compared to scaffolding in preventing falling accidents. One problem, however, is that safety accidents associated with gang-form works repeatedly occur due to worker carelessness. In this study, hierarchical checking tables are provided to support safety management activities for the gang-form works at the sites. Through a survey of experts and analyses of case studies of construction accidents, 137 safety check items are classified by participant type based on a hierarchical safety check scheme. The applicability and effectiveness of the hierarchical checking tables was evaluated through interviews with experts. It was found that the hierarchical checking tables enabled each gang-form related participant to check his own safety management items, and provided a level-wise structure to site safety management systems.

Construction safety should be considered prior to any other factors to execute construction projects smoothly and reduce the social expenses. Especially, the safety education is very important to the lives of labors and to control the four resources such as time, money, quality and safety. On this research, the present situation and related regulations of safety education are reviewed and the education contents and realities of the safety empirical education places are surveyed. Also questionnaire to education lecturers is performed to understand the satisfaction level of the education programs of the education places. Finally, the improvement directions are suggested to inspire trainees based on the results of the research.

The movement towards sustainable building design can result in unique fire protection challenges and concerns, especially with super tall buildings in relationship to traditional prescriptive code compliance. Different countries haves different code requirements as well as local best practices and may cause conflict with the design features when designing green buildings. These include, but not limited to green roofs, sprinkler water quality and testing, fire department access and areas of refuge with direct or indirect impact by the perspective code compliance. The solutions to these prescriptive code challenges and fire safety concerns can range from simple alternatives to more detailed engineering performance-based design analyses with good solid practice.
