Recently, an irregular-shaped super tall building has been increased, aiming toward landmarks of cityscape. However, the complex floor plan derived from an irregular shape requires considerable resources including time, cost, and effort to meet complex structural framework. Based on the motivation, the study proposes a table-form system that is variable slab form appropriate to an irregular shaped floor through improving limitations of an existing table-form system. The variable table-form is expected to reduce construction resources and improve constructability on an irregular floor plan of super tall buildings as well.

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.

본 연구의 목적은 초고층 복합건물 공사에서 마감자재 양중횟수를 산정하는 약산식을 제안하는 것이다. 그것은 양중계획 시 효율적인 데이터로 활용될 것으로 기대된다. 마감자재 양중계획은 건물이 고층화 될 수록 더욱 더 중요해 진다. 양중횟수는 "패키기"라는 방식을 통하여 기존의 방식보다 더욱더 정확하게 산정할 수 일다. "패키지"는 마감자재별 특성을 고려하여 한번에 양중할 수 있는 마감자재별 양중형식을 고려한다는 것을 의미한다. 도출된 약산식은 기준층 바닥면적과 단위면적당 실갯수라는 두 요소를 변수로 하여 도출하였다.

A tall building construction is needed to reduce the construction duration for project profitability. Reducing the cycle time of typical floor in the structural frame work which have the largest duration in the whole construction, greatly affects construction duration. Nowadays, some projects are accomplished in the 3 day cycle. In order to accomplish efficiently 3 day cycle, productivity information of similar projects is supported. Therefore, this study proposed labor productivity and application by slab formwork to construct by the 3 day cycle. In order to perform an analysis, we selected 3 cases and analyzed the labor productivity on the basis of the amount of slab forms, labors, and durations. Then, we performed the questionnaire to analyze the application by formwork of tall building construction engineers. This study will contribute to establish a reasonable scheduling in structural frame work of a new similar project.

In tall building construction, It is important to reduce construction duration of slab form work. Therefore, the purpose of this study is to assess the required performance for reduction of construction duration in slab form work of tall buildings. We surveyed the required performance and their degrees of importance and economical efficiency through the interview and questionnaire survey by related experts. This study proposes the guideline to develop improved formwork system for reduction of construction duration.

Recently, high-rise building projects have been in the spotlight in South Korea. Curtain wall construction, as one of important operations in the high-rise building projects is composed of various, entangled and complex unit processes that require a systematic planning to prevent unexpected delays. A schedule simulation technique has been used for deriving more efficient planning and accurate performance measurement. However, the simulation technique has difficulty in collecting actual data and in applying data fluctuations during construction. Thus, this paper suggests a concept model of Modular Simulation Model(MSM) that overcomes such limitations of traditional simulation technique based on curtain wall operations.

Recently, Society increasingly need the hish-rise building because of urban population concentration. and The hish-rise building need new systematic work-planning method. but it didn't use the construction project's work plan and management. his paper investigated efficient work-planning method. and the work-planning method in using domestic High-rise building's structure work. A investigated result is TACT, DOC LOB etc. and domestic using method is 3day and 4day-Cycle among the Tact. This paper is to compare and analysis two method. a purpose of paper is to analyse application through the case of using the work-planning method. also To find efficient method.

Formwork accounts for a large proportion of the framework in high-rise construction projects in terms of the duration and cost. Especially, slab formwork has a significant influence on these factors. However, the current selection of formwork method in general contractors depends on the decisions of few experienced engineers, and layout planning of the formwork in specialty contractors requires lots of time by different floor types. As a preliminary study for developing an optimum layout model in slab formwork of high-rise building construction, this study proposes the process of the optimum layout model and determines a fitness function for use of the genetic algorithm aimed at table formwork.

최근 급속하게 증가하고 있는 초고층 건축물은 바람이나 지진에 의한 횡변위를 효율적으로 제어하는 기술이 매우 중요하다. 그러나 국내의 초고층 주거형 건축물에 주로 사용되는 횡력 저항 구조시스템인 아웃리거 시스템은 별도의 공간을 요구하여 시공이 어렵고 공사 기간이 오래 걸리는 등의 불리한 점들이 있다. 반면 근래에 사용되고 있는 제진 시스템은 동적 하중에 의한 진동에너지를 부가적인 제진장치에 집중시킴으로써 건물의 횡변위를 저감시키며, 댐퍼의 설치도 비교적 용이하다. 또한, 아웃리거 설치와 같은 횡변위 제어시스템은 강성증가로 인해 풍응답이 증가되어 거주자의 불편과 같은 사용성 문제가 발생하기도 하며 이는 다른 추가적인 제어방식을 요구하게 된다. 따라서 본 연구에서는 초고층 주거형 건축물에 대한 횡변위를 효과적으로 제어하면서 아웃리거시스템을 대체 또는 보완할 수 있는 새로운 방법으로써 다양한 제진장치를 적용하여 각각의 횡변위제어 성능을 검토해보았다.
