  • Since vibration properties of a building structure were not easy to find out through a test, it was very difficult to in advance evaluate an influence of earthquake or other excitations on the building structure. However, currently, along with the development of the vibration analysis technique, it is possible to predict the structural performances of the buildings. The prediction of the vibration properties of the building structure has mainly employed a two-dimensional plane analysis so far, but not a three-dimensional analysis. The two-dimensional plane analysis encounters a reliability problem when the building is asymmetrical. This study has performed a three-dimensional modeling and vibration analysis on residential buildings when a subway passes below.

  • EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings. Modeling the performance of a building with EnergyPlus enables building professionals to optimize the building design to use less energy and water. This program provides energy analysis of building and needs weather data for simulation. Weather data is available for over 2,000 locations in a file format that can be read by EnergyPlus. However, only five locations are avaliable in Korea. This study intends to use AWS data for having high spatial resolution to simulate building energy. The result of this study shows the possibility of using AWS data for energy simulation of building.

  • Recent economic slump has highlighted the needs for the construction industry to develop strategies to improve productivity and overhaul organization structure. Notably, it is urgent to improve productivity of apartment building construction projects that account for about half of the aggregate revenue of building construction projects in Korea. As construction site management manpower staffing plan has close relation with the productivity of building construction, it is essential to staff construction sites adequately in consideration of site conditions and characteristics. However, construction companies of Korea are still far from developing site management manpower staffing plan in reference to quantitative standards. Therefore, this research aims to analyze site management manpower staffing plan of apartment building construction project by means of density analysis. To be more specific, site organization charts and staffing plans of apartment building construction projects put together by large construction companies in Korea are studied and essential resources and their mobilization time of apartment building construction projects are examined. Conclusions herein will provide basic inputs to subsequent studies of apartment building construction site management manpower staffing standards.

  • This study aims to monitor the variation of modal frequencies of steel buildings during their construction sequence. In this respect, construction of a steel building is followed by vibration based measurements. The monitored building is a three-story educational building within a building group whose structural system consists of steel moment resisting steel frames and eccentric braces. Five different acceleration measurements in two perpendicular directions are taken on five different construction stages, starting from the erection of the columns and beams ending with the completion of the construction. The recorded measurements are transferred into frequency domain and the dominant frequencies for each case have been determined. The change in the dominant frequencies is evaluated with the existing construction stages and performed constructional works between the stages. The last measurement, performed on the building in service, revealed the first two dominant frequencies as mutual in X and Y direction, showing that these dynamic modes are torsional modes. This result is investigated by numerical analysis performed with finite element model of the building constructed for design purpose. Lower frequencies and different mode shapes are determined from numerical analysis. The reason of lower frequencies is discussed and the vibration survey is extended to determine the effects of an adjacent building. The results showed that the building is in strong relation with an adjoining building in spite of a designed construction joint.

  • There are various types of energy simulation tool to predict both thermal load and energy use. However, the problem about these software is that they have too much input variables and need expert with skills to run the simulation. Therefore, the purpose of this study is to develop the thermal analysis simulation program with input variables which eliminates coordinates of building components instead of using full coordinates by using DOE2. Since the simulation engine of the program is DOE2, the validity of S-DOE is performed by comparing peak heating and cooling load results with VisualDOE and annual energy use results with actual energy use of 1996. The results have shown that there are little difference between VisualDOE and S-DOE. Also it showed that there are little difference between actual energy use and S-DOE energy use results. S-DOE took less time to model a building than VisualDOE. These results reveals that the application of S-DOE have potentials in accurately predicting both energy load and energy use of the building and still have an advantage of taking less time to model a building.

  • The pushover analysis is becoming a popular tool for seismic design of building structures. In this paper the state-of-art on static nonlinear analysis of building structures is presented with the emphasis on the effects of analysis parameters; i. e., lateral load patterns, modeling of members, and analysis computer programs. The analysed results may have variation even if a same structure is analysed. This paper is to investigate how large the variation is and what the main causes of the variation are. The difference of analysed results, the resultant variation of lateral story shear force and flexural strength of structural members are discussed. The pushover analysis procedure are routinely used in the seismic design of building structures, but some problems must yet be clarified, such as the effects to evaluate the parameters of analysis on the basis of a lateral load patterns and modeling of members.
