영국의 "기업과실치사법", 캐나다 및 호주의 기업처벌을 강화하기 위해서 형법을 개정하였음에도 불구하고 산업재해 감소 효과는 미미하다. 건설 현장의 불안전한 상태 방치 및 가설구조물에서 강도 높은 안전사고가 다수 발생하고 있다. 본 연구에서는 이러한 안전사고 예방을 위해 안전관리 실명제의 중요도 순위를 전문가 설문으로 도출하였다. 건설현장 전문가를 대상으로 AHP모형을 통해 중요도 분석한 결과 상위계층은 건설기계가 가장 중요하다고 보았으며, 하위계층의 안전시설물 관리에서는 개구부, 건설기계에서는 타워크레인, 관리실명제에서는 "산업안전보건법" 상에 의한 관리, 안전관리조직에서는 CEO의무가 가장 중요하다고 보았다. 안전관리실명제의 기대되는 역할은 중대재해처벌법이 예방에 힘쓰기 보다는 방어에 온힘을 다하느라 예방의 기능이 저하되고 있다. 이러한 역 기능을 바로잡기 위해 안전관리실명제는 중요하다.

In this study, the deformation analysis is done at tower crane by applying the load at the end of jib and the moment at mast. The greatest stain and stress are happened at the end of wire supporting jib. The great deformation takes place at the end of jib applied by stress and there is no deformation at the lower part of mast. As the life becomes smallest at the upper part of mast, this part becomes weakest. The safety design and durability can be improved by applying the result of structural safety analysis at tower crane.

The purpose of this study is to develop the process to support and evaluate experts' decision making on vertical transportation planning in high-rise building constructions. Experts generally carry out the vertical transportation planning by heuristic methods, so there is a possibility that their decisions failed. The failure of the vertical transportation planning can be result in much loss of time and cost. The process presented in this paper evaluates experts' alternatives, organizes the results of the vertical transportation plan, and then leads to the systematic flow of materials and crews.

A deck crane is installed on the deck of a ship by lifting method using tower crane or floating crane. The safety assessment for two points lifting method should be preceded to ensure a safe installation of deck crane. In this study, finite element models of deck crane and fixing jig are generated for the structural analysis which can evaluate a safety of lifting method. Also, reaction forces and boundary conditions considering lifting state are applied to the structural analysis. The proposed safety assessment method can be useful as an analytic tool that can provide a safer procedure for installation of deck crane by lifting method.

It is critical to select the appropriate type of tower cranes for the construction of super tall buildings. However the selection is often made based on subjective personal experiences due to the lack of historical and analytical data. As a result, planning mistakes and efficiency errors sometimes occur. This research is to develop a system of hoisting analysis for appropriate tower crane selection and to provide a flexible statistical model based on the Burj Dubai project. In addition, this system hassupporting functions that can estimate the target construction period per floor, and a decision-making construction period computation method which is based on the characteristic of the selected tower cranes.

Gangform compared with conventional wood and steel form is systemized form which has a capability to install and dismantle form at a time without repeating to assembly and disassembly small members. Gangform compared with ACS has some problems such as 1) Tower Crane load increase, 2) increase in safety incidence during climbing Gangform, 3) decrease in detachment operation productivity, 4) stop work due to climate impacts, and 5) decrease in labor cost, productivity, quality. A conceptual design model of automated Gangform climbing system is suggested for apartment housing construction to show its technical/economic feasibility and workers' safety while increasing operation productivity and concrete quality.

In this paper the structural analysis of a planet carrier was carried out for the design optimization of a slewing reducer used in tower cranes. The stress changes of the planet carrier according to the tolerance of interference fit were investigated, and the strength was evaluated on the basis of the stress level. The analysis results showed that the tolerance of interference fit have an important influence on the stress level of the planet carrier. To guarantee the static safety of carrier, the tolerances of carrier pinhole and planet pin as well as loading level exerted on the planet carrier should be determined considered correctly.
