While non-uniform shapes are appearing as an apparent building style recently, most architects predominantly think structure and construction technology should support the designed shape of non-uniform structures determined by the architect. Within such a governance structure of architect's perception, the role of an engineer is emphasized for technical support only. Especially, in making a decision on a structural design and plan, if various and objective reviews are not conducted, the design is very likely to be left only as a drawing even if the design is appropriate for criteria and norms. With the recognition of such problems, the present study attempted to propose an equal cooperative relationship between architects and engineers in designing non-uniform structures in the future.

Large logistics centers are being built around the world. Most of these buildings have characteristics of long span and heavy load, and use PC (precast concrete) structure for quick construction. There have been few attempts to systematically analyze the various influencing factors of PC erection planning. In this study, we intend to analyze the influencing factors necessary for the creation of a sustainable PC erection planning algorithm.

In the case of precise safety inspection and precise safety diagnosis of a building, a condition evaluation must be conducted to determine the safety grade. Since 2004, an evaluation method using fuzzy theory has been introduced for quantitative condition evaluation,and the relationship and importance of reinforced concrete members using fuzzy theory have been applied. Generally, fuzzy theory is a method used to deal with ambiguous expressions with unclear correlations, but at the time of development, it seems that it was developed by applying fuzzy theory as an alternative in a situation where inspection and diagnosis result data were insufficient. Therefore, it is necessary to verify the relationship and importance of evaluation items derived based on the current fuzzy theory using actual inspection and diagnosis result data.In this study, the correlation between the evaluation items was derived by using the results of 19 precision safety inspections and 9 precision safety inspections and the performance score function formula, and using this, a reasonable durability score calculation formula of the member was presented.

This study was begun on the premise that architecture which has the definite disposition for survival even in the urban, social structure of that uncertainty and constructs specialty is biomorphic architecture. This study was organic philosophy background analysis of Biomorphic architecture occurrence, through meaning inherent analysis in Biomorphic architecture, which going to be deployed atypical and new shape one. Biomorphic architecture is organism shape of structure of autonomous survival, which is shaped the potential of biological phenomena. Theoretical analysis of the Biomorhpic architecture characteristic was analysed. Factor in the occurrence of Biomorphic architecture based on an objective analysis of the research is characteristic analysis. Which is reason as the 'create', the science of complexity and emergent System. The generation causes of biomorphic architecture are an organic philosophy. Biomorphic architecture makes the realization of simile form using the procedural principle represented by in natural phenomena.

현대 건축은 시공 기술과 재료생산 및 개발의 발전을 바탕으로 점차적으로 투명성을 띄게 되었다. 이러한 건축적 투명성은 재료나 기술적인 발전도 많은 영향이 있었으나 그 보다 사용자들의 공간적 인지와 요구에 맞춰 생성되었다고 볼 수 있다 본 논문은 도미니크 페로의 프로젝트를 바탕으로 건축 공간적 투명성의 근본적 요소들을 분석하여 프로젝트에 나타난 공간적 구획과 인지에 대해 알아보았다. 도미니크 페로는 투명성을 건축적 구축방법 및 표현방법으로 사용하는 것으로 나타났고, 건축물이 하나의 고립된 물체로 보기 보다는 대지와 건축물의 구분이 불분명하여 공간적인 경험이 건축물과 대지의 경험을 넘나들게 만들어 진 것을 볼 수 있다. 실내공간의 투명성은 공간 구획에서 표현이 되었는데, 도미니크 페로의 대부분의 프로젝트에는 매우 간단하고 개방된 구획을 추구한 것을 미뤄 볼 때 실내 공간구획과 외부와의 밀접한 관계를 동시에 설계한 것을 알 수 있었다. 공간적으로나 표피적인 투명도가 높은 공간의 사용하는 사용자의 생활패턴이나 공간적 인지에 미치는 영향을 살펴보았을 때, 개방된 공간이나 공간적 노출에 의식하지 않고 자연스럽게 적응하는 것을 알 수 있었다. 현대건축 공간에 나타나는 투명성은 물리적인 영향보다는 사용자의 공간인식과 시각적 인지에 큰 영향을 미치는 것으로 판명되었다.

Recently, the construction industry has seen the emergence of interior and exterior finishes using ultra-high performance concrete (UHPC) and colored concrete products using precast concrete (PC). However, the excessive amount of pigment used for coloring reduces the strength of the concrete. There is a need to improve the durability and chromaticity of colored concrete, and further analytical studies on the properties of colored concrete are also required. Therefore, in this paper, colored ultra-high strength cement composites (C-UHSCC) containing red and green inorganic pigments were prepared, and the compressive strength and color of the specimens were measured according to the age, and the correlation between strength and color was analyzed by simple linear regression analysis using R² value. The results showed that the red color was highly correlated with L^* and a^*, and the green color was highly correlated with a^*. These results can be considered for various concrete formulations, but research is needed to suggest the optimal pigment mixing ratio for proper strength and color development.

In this study, a series of flat dilatometer tests are performed for Busan sand reconstituted in a large calibration chamber to evaluate the state parameter ($\Psi$). Experimental result shows that the horizontal amplification factor ($K_D/K_0$) is linearly related with state parameter in semi-logarithmic space, but the $K_D/K_0$ of OC specimen is smaller than that of NC specimen because of the horizontal residual stress by stress history of OC specimen. The relation between the normalized dilatometer modulus ($E_D/\sigma_m'$) and the state parameter is also linearly expressed in semi-logarithmic space, and the effect of stress history is relatively insignificant in this relation. However, the variation in $E_D/\sigma_m'-\Psi$ relation of NC state is slightly higher than that of OC state due to the effect of the stress level, and the correlation curve is descending with increase of confining stress. The comparison of test result with previous results of Ticino and Toyoura sands shows that the $E_D/\sigma_m'-\Psi$ relation of Toyoura sand is located on upper side than that of Busan and Tieino sands due to the effect of the higher compressibility, whereas the $K_D/K_0-\Psi$ relation of each sand is irregularly distributed.
