This study introduces the development of a precast concrete double-wall, applicable to basement construction in apartment buildings. Unlike traditional precast concrete double walls, the developed double-wall doesn't require specialized manufacturing equipment such as a lathe. The constructability of these advanced technologies was validated through a full-scale mock-up test using the precast concrete double wall. The test specimens were constructed to represent a structural wall with a thickness of 250mm. It was observed that the quality of the in-situ concrete, filled between two single panels of 110mm thickness each, was excellent. The construction efficiency of the developed double-wall system for basement construction in an apartment building was also examined. Expert interviews about installation times of precast concrete elements were conducted to evaluate the speed of the basement floor's installation. The results showed that installation of precast concrete elements, including the proposed double walls, could be completed within 20 to 29 days for a basement in an apartment building. This indicates a three-fold increase in construction efficiency compared to traditional methods relying on in-situ casting.

Cracks are caused by drying shrinkage between the upper part of the underground parking lot and the apartment wall. As a result of the investigation, the distance between the apartment and the apartment is more than 45m, and the top slab of the underground parking lot is usually flat when there is not with steps. Therefore, the crack occurs more when the underground parking lot is a PC slab than a RC slab. In this study, the reduction of cracks was conducted by extending the slab, expanding the beam size, increasing the wall thickness, and installing a delay joint on slab. In each case, a finite element analysis was performed to examine the crack reduction method.

This research accomplished the seismic perfomance evaluation in the domestiv airport facility underground parking by the seismic design standard of airport facility. The seismic perfomance evaluation for the design ground motion decision and liquefaction was accomplished in the two-dimensional elastic-plastic dynamic analysis. This study presented analysis model, analysis methed and design procedure suited to perfomance level.

최근의 건물의 동향을 보면 아름다움을 강조하여 비틀리고, 경사지고, 테이퍼형태를 가지고 있다. 이러한 건물에 대응하는 구조시스템으로 대형 대각가새 구조시스템이 등장하였다. 이 구조시스템은 건축적인 요구사항을 만족하면서 구조물량 절감의 가능성이 있지만 다수의 부재가 만나는 접합부에 대한 구조성능 평가가 필요하다. 이에 본 연구에서는 H형 단면을 이용한 대형 대각가새 구조시스템의 접합부에 대한 단조가력 실험을 수행하였으며 하중 및 변형능력을 평가하였다. 주요 변수로는 부위별로 용접방법 및 웨브의 이음길이를 적용하였다. 실험결과 완전용입용접에 대하여 국부적으로 부분용입용접을 사용한 경우와 비교해 보면 구조성능에는 차이가 없었고, 웨브의 중첩길이는 웨브사이 이격거리에 100%에 해당하는 길이가 필요함을 알 수 있었다. As number of the buildings increases, it shows new trends such as twisted, tilted, taperer shape. As a structural solution for the new trend buildings, diagonal grid (Diagrid) structure was developed. Though a few buildings was built using diagird system, the structural performance of the corresponding node was not clearly identified. Therefore, experimental evaluation is needed to apply diagrid for higher buildings. In this study, the node was tested depending on the amounts of welding materials. As a result, the partial welding can provide enough strength for the node as required in the full penetration welding under monotonin compressive loadings.

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.
