  • This paper attempts to identify the term "tectonics" comprehensively by collecting and categorizing existing definitions of tectonics within the architectural area rather than to stress the concept of tectonics of each specific theorist. Although no consensus of opinion on the concept of tectonics exists, architectural tectonics was closely related to the following terms in three categories: 1. $techn\acute{e}$, technique, and technology; 2. construction and structure; and 3. stereotomics. Based on its etymology, system, and material construct, the notion of tectonics common in these three categories signifies "the art of framing construction," in which linear elements are connected with joints and clad or infilled with lightweight material. Thus, the art of framing construction, as a common concept of tectonics, reveals the following characteristics: First, tectonics is based on framing construction in contrast to piling-up construction as the etymology of tectonics signifies the art of carpentry. Then, the term tectonics, dealing as it does with a higher level of construction rather than the mechanical level of structure, incorporates the poetic aspect of techne as well as the rational aspect of technology. Third, Owing to the organic, double system of tectonic frame and incrusting or infilling materials, the tectonic body becomes both the ornament and the structure simultaneously. As the art of framing construction is based on material construction rather than structural or ornamental form, this paper proposes that one can view tectonics as a term that conveys the meaning of the actual material effect on space.

  • The aim of this paper is to determine the effect of soil-structure interaction and time dependent material properties on behavior of concrete box-girder highway bridges. Two different finite element analyses, one stage and construction stage, have been carried out on Komurhan Bridge between Elazi$\breve{g}$ and Malatya province of Turkey, over Fırat River. The one stage analysis assume that structure was built in a second and material properties of structure not change under different loads and site conditions during time. However, construction stage analysis considers that construction time and time dependent material properties. The main and side spans of bridge are 135 m and 76 m, respectively. The bridge had been constructed in 3 years between 1983 and 1986 by balanced cantilever construction method. The parameters of soil-structure interaction (SSI), time dependent material properties and construction method are taken into consideration in the construction stage analysis while SSI is single parameter taking into consideration in the one stage analysis. The 3D finite element model of bridge is created the commercial program of SAP2000. Time dependent material properties are elasticity modulus, creep and shrinkage for concrete and relaxation for steel. Soft, medium, and firm soils are selected for evaluating SSI in both analyses. The results of two different finite element analyses are compared with each other. It is seen that both construction stage and SSI have a remarkable effect on the structural behavior of the bridge.

  • Inorganic binding material was made by recycled resource and its applicability as pile-filling material was examined. The result was that the material had same liquidity with the liquidity of OPC and high reactivity with site soil. According to dynamic/static loading tests by site test-construction, the inorganic binding material met both design bearing capacity and settlement. Since the inorganic binding material showed same or better performance than OPC, the utilization possibility of the inorganic binding material made of recycled resource as pile-filling material was verified.

  • This study aims to estimate the relative importance of quality management items through the defect analysis in the landscape construction process. The RIQMI are decided by the defect coefficient and it's cause weight. The defect items in the landscape construction process were classified by 56 items based on the classification form of '96 landscape architectural construction standard and the cause pattern were categorized 4 types as design, material, construction, and environment factors. To analyze the defect coefficient and the aucse weight by defect, the researcher surveyed the questionnaires on the 103 engineers and the 31 experts on the landscape architectural construction. The result of this study are as follows. The relative importance by facilities pattern turn out to be much higher construction, material fator than design. environment factor in wood facilities, paving facilities, and steel facilities, the RIQMI is very high in timber crack, timber vending, faulty of timber against decay, welding faulty of steel facilities in material factor, and timber crack, faulty of timber against decay, finish faulty of steel facilities, welding faulty of steel facilities in construction factor.

  • 본 연구는 조경공사 표준품셈의 개정 작업이 진행되고 있는 현시점에서 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘의 식재 공종의 내용의 특성을 비교하여, 향후 한국의 조경공사 표준품셈의 발전에 기여하는데 연구의 초점을 두고 진행하였다. 표준품셈과 표준보괘의 특성을 파악하기 위해서 한국의 경우는 2010년 '국토해양부'에서 제정한 건설공사 표준품셈 공종내의 조경공사를 연구 대상으로 하였다. 또한 일본의 경우도 2010년 '국토교통성' 제정 토목공사 표준보괘의 공원식재공사 표준보괘를 연구대상으로 하였다. 그리고 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘 공종 중에서 식재 공종에 초점을 두고 품셈의 범위, 세부 공종, 품셈의 구성, 수목 적용 규격, 품셈의 내용 등의 비교를 연구의 내용적 범위로 한정하였다. 한국의 조경공사 표준품셈과 일본의 공원식재공사 표준보괘의 식재 공종의 내용을 비교하여본 결과, 한국의 조경공사 표준품셈은 독립적인 품셈과 품셈의 적용에 있어 융통성이 필요하다. 그리고 지주목에 대한 독립적인 품셈과 운반에 관한 품셈 규정 그리고 조경토와 관련된 품셈 등의 검토를 통하여 한국의 조경공사 표준품셈이 더욱 발전할 수 있다고 판단된다.
