The engineering background of this article is an ancient wooden building with extremely high historic and cultural values in Tibet. A full understanding of the dynamic behaviour of this historic building under in-service environments is the basis to assess the condition of the structure, especially its responses to earthquake, environmental and operational loading. A dynamic monitoring system has been installed in the building for over one year and the large amounts of high quality data have been obtained. The paper aims at studying the dynamic behaviour of the wooden building in seismic and operational conditions using the field monitoring data. Specifically the effects of earthquake and crowd loading on the structure's dynamic response are investigated. The monitoring data are decomposed into principal components using the Singular Spectrum Analysis (SSA) technique. The relationship between the average acceleration amplitude and frequencies of the principle components and operational conditions has been discussed. One main contribution is to understand the health condition of complex ancient building based on large databases collected on the field.

When faced with new projects, such as high-rise, complex, free-formed, and sustainable buildings, numerous participants in the building Industry use Building Information Modeling (BIM) technology. In 2009, the use of BIM spread to more contractors than eyer before. This paper aims to study the definition and characteristics of BIM, and to analyze Korean BIM application problems. Solutions for the application of BIM to the Korean Construction Industry suggested, by studying cases from developed counties and from Korea.

Cable net system openness and flexibility is good high and the large deflection caused no damage to the structure itself. However, cable installation, install complex systems and technologies are needed. In this study, for the basic materials of cable net construction management, cable net expert's advice and mock-up test results are summarized.

A mixted integer non-linear programming model which has the object function as minimizing building costs, and constraints with the functions for carrying capacity and service level of queueing time is developed. By using the proposed model, the most adequate on a building and the most economical elevator's specifications could be determined by sequential search method like complex method.

A summary of the main results from an international comparative study for the high-frequency base balance is given. Two buildings were specified - a 'basic' and an 'advanced' building. The latter had more complex dynamic response with coupled modes of vibration. The predicted base moments generally showed good agreement amongst the participating groups, but less good agreement was found for the roof accelerations which are dominated by the resonant response, and subject to measurement errors for the generalized force spectra, to varying mode shape correction techniques, and different methods used for combining acceleration components.

This study aims to solve environmental problems by reducing complex degradation and recycling industrial waste by utilizing waste fibers and blast furnace slags, which are industrial by-products. In addition, it is intended to secure long-term durability to reduce cracks. To this end, the disadvantages of fiber-reinforced concrete are to solve the problem of lowering liquidity and ensuring curing time, and to find the optimal combination when waste fibers and blast furnace slag are used together.

When measuring fine dust at a large-scale site such as complex construction, the change in the value of fine dust measurement is large due to the influence of the time, location, wind speed, wind direction, and humidity. This study aims to find out the results of measuring fine dust in an actual construction site and inferring the changes.

This study is performance estimation of wind augmentation device for BiWP(Building-integrated Wind Power) which recently attracts attention as a local power. various structures are installed on a rooftop of residential complex buildings. Changing a profile of these, we designed a configuration that is able to capture much air and increase exit velocity. To estimate wind augmented effect of this device, we compared numerical analysis results with wind tunnel test results. Results show that exit velocity is increased from 24% to 60% by wind augmented device on a rooftop of building.
