Selecting the best materials that ensure maximum performance is crucial in construction engineering design of any project. However, this challenging and usually not properly considered because lack systematic scientific evaluation methods for materials. This paper proposes a new approach selecting material to satisfy goal designers building constructions based on analytic hierarchy process method. To validate suggested model, case study was conducted concrete system form, which susceptible...
Understanding the structure and behavior of emissions in building systems is first step toward improving reliability environmental impact assessment buildings. The shortcomings current lifecycle (LCA) research lack understanding embodied static analysis. This study presents a methodology for dynamic LCA buildings, combined with system dynamics technique. Dynamic factors related to recurrent are explored through literature review. Applying based on review, causal map stock-flow diagram...
We propose a technique for obtaining the skeleton curve of moment-rotation relation at column base traditional timber buildings form local compression tests wood elements. In experiment, rotated specimen is pressed into foundation stone keeping rotation angle constant. From this we obtain relationships between amount reaction force from and its acting position specified angle. Noting that moment can be expressed by multiplying action, predict relationship set tests, where changed as an...
There are many factors in a common building project that not relevant for free-form tall projects, example, the planes or various shapes of buildings. Among risks present particular structural frameworks, risk delays is an important one and has considerable effect on entire performance. Generally, delay causes decrease constructability increase cost, so eventually productibility framework would decrease. Delay management frameworks buildings currently performed by managers based personal...
Building Information Modeling (BIM) can act as a solution to improve various difficulties faced in the construction industry. BIM is expanding into infrastructure facilities for integrated information management, productivity improvement, and risk management. There are many cases where applied buildings with horizontal linear characteristics, but different from method of applying vertical characteristics. Using premanufactured libraries BIM-based design shorten time simplify method, thus...
The current method of estimating CO2 emissions during the construction phase does not consider variability that can occur in actual work. Therefore, this study aims at probabilistic estimation dealing with statistical characteristics activity data building work, focused on concrete pouring work and based field data. probabilistically estimated have some differences from measured by deterministic methods. results revealed minimum difference was 11.4%, maximum 132.7%. This also used Monte...
We report the results of static friction tests between column base and foundation stone Japanese traditional timber buildings. Through tests, we examined effect shape section, rotation angle column, number loading cycles on variation coefficient. The coefficient obtained from test ranged 0.7 to 0.9 in first cycle. Up 30% reduction was observed second In addition, concrete foundation, where cycle more significant.
최근 국가적으로 수도권광역급행철도 공사가 진행되고 있다. 도심 내의 터널 굴착공사 시 진동, 소음이 발생하며 이로 인한 인근 거주자에 불편한 영향을 미칠 수 이와 같은 상황을 대비하고자 건설사는 공사계획단계에서부터 인근지역의 주민들과의 협의, 제기된 민원에 대한 대응방안 수립 등으로 현장 내 소음 및 진동 관리계획을 수립한다. 그러나 관리계획 수립에도 불구하고, 공사기간 동안 산발적으로 발생하는 소음과 진동으로 인해 민원이 근본적으로 해결되지 못하고 문제점을 해결하기 위해서 프로젝트 계획단계에서부터 인근지역 주민들 대상으로 현실과 몰입감이 높은 시뮬레이션 기술을 제공하는 것이 하나의 해결책일 따라서 본 연구는 현실감과 몰입감을 높일 있는 가상현실을 기반으로 발파진동을 직접 체험할 발파진동 시뮬레이터를 개발하였다. 연구 결과는 향후 굴착공사계획 민원대응에 효과적일 것으로 예상된다.
System form is widely used when constructing concrete buildings and structures because it has high productivity good casting quality compared with traditional hand-set form. However, from a worker’s perspective, system still very harsh to handle of its heavy weight, noise generation, use releasing agent, also attenuates the formwork. Therefore, this study proposes an advanced composite material-based for workers using Design Six Sigma (DFSS) process improve constructability User requirements...
