In this paper, it was tried to prove the possibility and effect of coordinate measurement by using MEP layout equipment at the construction stage, and to propose a method to improve measurement accuracy during construction. For this study, the passenger terminal site, which is a long span structure, was selected and compared with three dimensional CAD drawings and construction measurement results using MEP layout equipment for the precise construction of long-span irregular curved roof layers. As a result, it was found that it is possible to construct three-dimensional curved roof layers using MEP layout equipment through measurement and analysis.

A lot of push-out test results of studs in normal strength concrete have been presented. So present design methods in the codes for the calculation of the shear strength of studs are based on the test results of studs embedded in normal strength concrete. But knowledge of the load-slip behavior and the shear capacity of the stud in high strength concrete are limited to data obtained from the experimental push-off tests. So It is necessirary to evaluate the shear capacity of studs embedded in high strength concrete for the appropriate design code. Because it shows that the concrete compressive strength significantly affects the strength of the stud connections. In this paper, it was performed push-out test of shear studs in high strength concrete used in construction of high-rise building. Test results are compared with them calculated from current design codes.

The aim of this study is to estimate the compressive force of steel member using a system identification technique with vibration measurements. To date, several methods have been presented to estimate the compressive force using static and/or dynamic responses of the steel member. However, each and every one of these methods has its disadvantages as well as advantages in its procedures, level of accuracy, and equipment requirements. The paper reports a qualitative investigation of vibration under mono harmonic excitation. The methodology utilizes the relationship between the natural frequencies, the structural parameters, and the compressive force of the member. In this paper, experimental results are presented with a steel beam subjecting to several compressive forces and the proposed method is validated using both numerical and experimental data.

High rise buildings vibrate sensitively by the strong wind with reduction of weight and damping ratio recently. As increased the high rise buildings, a lot of people appeal the problems in serviceability caused by intensive vibration of building when strong wind has passed. In this paper, the active mass damper (AMD) which adopts the H∞ control algorithm is designed and applied to a exist building structure. This may be the first full-scale application of AMD to the existing building in the world. Two AMDs, which have 20 ton mass and 10 ton mass for x-axis and y-axis, respectively, are installed on the roof of the builidng structure, and those AMDs are design to control not only transverse response but also even torsion responses. In order to verify the performance of the AMD system, the controlled responses of the building structure are measured during a typhoon passes through the Korean Peninsula and compared with the uncontrolled responses obtained by a numerical simulation.

A lot of push-out tests of shear studs embedded in normal strength concrete were conducted. So current design code methods of the shear studs are based on the test results of studs embedded in normal strength concrete. It also appeared that the strength of connector and the concrete strength are the main factors affecting the behavior of shear connections. But push-out test data of studs embedded in high strength concrete is insufficient until today. So it is necessary to evaluate the load-slip behavior and the shear capacity of studs embedded in high strength concrete for the appropriate design code. In this paper, it was performed push-out tests of shear studs embedded in high strength concrete and fiber reinforced concrete used widely in high-rise building. Experimental push-out tests were used to evaluate both the shear stud capacity and the load-slip curve of the connector. And the results of the finite element model are compared with push-out tests and the values given in current codes of practice.

The underground method can be divided into Top-Down, Semi-Top-Down, Up-Up and Down-Up methods according to the construction order of the upper and lower structures. Among them, the Down-Up method proceeds with the construction of the first floor and its lower floors, and when the foundation is completed, the vertical members of the basement are sequentially completed from the foundation and the above-ground floor is constructed. In this paper, the crack reduction method around the open section of the Down-Up method affected by earth pressure was analyzed and divided into design and construction parts.

Top-down construction is a useful method of utilizing the working space, economic benefits and shorten the construction period. Precision construction of the elevator core is very important for safety of the top-down structure. In this study, the layout system for the field-BIM(Building Information Modeling) was used to precisely construct the elevator core in the basement and the ground. Through the layout system, it was possible to process the construction status, review the design results and construction errors, and confirm whether there is or not within the construction error range for elevator installation.
