소비의 패턴이 이성소비에서 감성소비로 전환되면서 오감이 중요한 마케팅 요소로 등장하고 있다. 특히 시각적 요소는 인간이 사물을 인지하는데 있어서 83%정도의 영향력을 발휘하기 때문에 매우 중요하게 고려된다. 따라서 본 연구는 Color Code를 토대로 사용자의 성격을 분류하고 동시에 사용자가 선호하는 색상을 이용하여 색채배색을 제안하는 방법을 설명하고 있는데 성격을 RED, BLUE, WHITE, YELLOW의 4개의 컬러코드로 분류하기 위해서 ‘The Hartman Color Code Personality Profil’을 이용하였다. 조사결과 사용자의 컬러코드 중 가장 많은 코드는 BLUE코드였으며 선호도도 가장 높았다. 이러한 BLUE 코드의 특징 중 색채와 대응할 수 있는 감성어휘를 중심으로 색채배색안을 제시하고 이를 주택상품의 컬러마케팅에 이용하고자 하는 것이 본 연구의 목표이다.

Generally significant reinforcement is used in nuclear power plant structures and may cause potential problems when concrete is poured. In particular pouring concrete into structural member joint area is more difficult than other areas since the joint area is very congested due to the crossed bars and the embedded plates, The purpose of this study is to solve these problems by applying Gr.80(550MPa) shear bars to containment structures of nuclear power plant. In order to apply them to containment structures, it is necessary to change ASME-CC code (ASME Sec.III Div.2). The structural performance tests of wall & beam have been done to compare Gr.80(550Mpa) with Gr.60(420MPa) shear bars. The test results and code change proposal were presented to ASME-CC Committee last year and the discussion for code change will be expected to proceed in the near future.

Nonlinear seismic performances of code designed Perforated Steel Plate Shear Walls (P-SPSW) were studied. Three multi-storey (4-, 8-, and 12-storey) P-SPSWs were designed according to Canadian seismic provisions and their performance was evaluated using time history analysis for ground motions compatible with Vancouver response spectrum. The selected code designed P-SPSWs exhibited excellent seismic performance with high ductility and strength. The current code equation was found to provide a good estimation of the shear strength of the perforated infill plate, especially when the infill plate is yielded. The applicability of the strip model, originally proposed for solid infill plate, was also evaluated for P-SPSW and two different strip models were studied. It was observed that the strip model with strip widths equal to center to center diagonal distance between each perforation line could reasonably predict the inelastic behavior of unstiffened P-SPSWs. The strip model slightly underestimated the initial stiffness; however, the ultimate strength was predicted well. Furthermore, applicability of simple shear-flexure beam model for determination of fundamental periods of P-SPSWs was studied.

This study examined the efficacy of development control in the monitoring of building developments in Kenya, a case study of Kisii Town. It focused on the extent to which the 1968 Building Code was enforced by the County Government of Kisii in an attempt to promote quality assurance. The target population comprised 7,430 residential developments from where a sample size of 364 was proportionately and randomly drawn. Research findings indicated that 39% of developers were unaware that their developments should have been inspected during construction. Similarly, awareness of building inspection significantly predicted if developers issued Notices of Inspection to the planning authority to facilitate inspections. Consequently, developers who were unaware that their building constructions required inspection were 99.9% less likely to issue such notices. Moreover, developers who did not obtain development permission were correspondingly 99.9% less likely to issue Inspection Notices. As a result, those who did not issue Notices of Inspection were 99.8% less likely to have their buildings inspected during construction due to lack of records indicating when such constructions had commenced. The study concludes that although the County Government of Kisii is lawfully mandated to monitor building developments in Kisii Town, the function is not well executed. This gap affords developers with an opportunity of not conforming to the approved building plans.

Nonstructural elements are installed according to the function of a building, and refer to the elements other than a structural system that resists external loads. Although the nonstructural elements had the largest part of seismic loss of buildings, seismic design of buildings mainly focuses on structural system and the seismic design of nonstructural elements are rarely conducted. In this study, the seismic design provisions of nonstructural elements presented in Uniform Building Code (UBC) and International Building Code (IBC) were investigated in order to analyze the seismic design considerations of nonstructural elements presented in Korean Building Code (KBC). The results showed that the equivalent static load applied to seismic design of nonstructural elements was revised to take into consideration a total of five items such as effective ground acceleration, vertical amplification factor, response amplification factor, response modification factor, importance factor.

The building design codes and standards in many countries usually are either fully or partially adopted from the international codes. However, regional conditions like the quality of construction industry and different statistical parameters of load and resistance have essential roles in the code calibration of building design codes. This paper presents a probabilistic approach to assess the reliability level of adopted national building codes by simulating design situations and considering all load combinations. The impact of the uncertainty of wind and earthquake loads, which are entirely regional condition dependent and have a high degree of uncertainty, are quantified. In this study, the design situation is modeled by generating thousands of numbers for load effect ratios, and the reliability level of steel elements for all load combinations and different load ratios is established and compared to the target reliability. This approach is applied to the Iranian structural steel code as a case study. The results indicate that the Iranian structural steel code lacks safety in some load combinations, such as gravity and earthquake load combinations, and is conservative for other load combinations. The present procedure can be applied to the assessment of the reliability level of other national codes.

The application of all regulations during building phase, plus constant vigilance in operation is essential to reducing the risk of fire aboard. A Safety by design approach is increasingly important. Fire safety regulation can solve problems which are hard to be solved by HSC code(International Code of Safety for High Speed Craft). Recently HSC code is applied for ship design development or guidance to the designer and demonstrates many advantages. In this pages, ship fire Safety are realistically modeled as ship design and the shipboard fires & muster stations are analyzed using HSC Code.

This study was performed to develop an LRFD (Load Resistance Factored Design) Code for Domestic Larch. To accomplish his, we evaluated bending, compression, tension and shear strength. The results of the strength evaluation were utilized to verify the distribution and code conversion. For bending, tension and compressive strength, the Weibull distribution was well-fitted, but for shear strength we observed a normal distribution. For evaluating the bending and compressive strength, a full-sized specimen was used. A small clear specimen was used to test tension and shear strength. Compressive strength in particular was found to be affected by tight knots, although there was little difference between grades. In the code conversion, the design value of the LRFD was larger than the existing allowable stress value in the Korean Building Code. However, the allowable stress in this study was about two times higher than the value listed in the Korean Building Code. This result induced the difference between the soft and hard conversions. For greater reliability, the accumulation of additional data is necessary and further studies should be performed

In the past two decades, researchers from different countries have conducted series of experimental and theoretical studies to investigate the behaviour of structures in fire. Many new insights, data and calculation methods have been reported, which form the basis for modern interdisciplinary structural fire engineering. Some of those methods are now adopted in quantitative performance-based codes and have been migrated into practice. Mainly based on the achievements in structural fire research at China, the Chinese national code for fire safety of steel structures in buildings has been drafted and approved, and will be released in this year. The code is developed to prevent steel structures subjected to fire from collapsing, ensure safe evacuation of building occupants, and reduce the cost for repairing the damages of the structure caused by fire. This paper presents the main contents of the code, which includes the fire duration requirements of structural components, fundamental requirements on fire safety design of steel components, temperature increasing of atmosphere and structural components in fire, loading effect and capacity of various components in fire, and procedure for fire-resistant check and design of steel components. The analytical approaches employed in the code and their validation works are also presented.
