This paper reports the study on the shrinkage property of expansive strain-hardening cement-based composite (SHCC) materials containing 1.5% polyethylene (PE) fibers volume fraction. Variables were cement types (ordinary portland cement, OPC and ultra-high early strength cement, UESC) and 2 replacement levels (0, 10%) of an expansive admixture (EXA). A number of experimental tests were conducted to investigate shrinkage and compressive strength. The test results indicated that using UESC improves compressive strength of SHCC. Also, replacement of EXA on SHCC can reduce the huge shrinkage value and EXA has fewer effects on UESC specimens than OPC specimens.

This paper reports on a comprehensive study on the mechanical properties of expansive fiber-reinforced strain-hardening cement composite (SHCC) strengths(30 and 70MPa) materials containing various replacement levels (0 and 10%) of an expansive admixture and 1.5% polyethylene (PE) fibers volume fraction. A number of experimental tests were conducted to investigate compressive strength, flexural strength, and direct tension behavior. Test results show that as expected, the different replacement ratio of an expansive admixture have an important effect on the evolution of the Materials of SHCC with a rich mixture. Test results show that as expected, the different replacement levels of an expansive admixture have an important effect on the evolution of the free shrinkage of SHCC with a rich mixture. As an alternative under expansive admixture evaluated the performance of SHCC expansive admixture alternative than if the substitution did not substantially improve performance, the expansion of the alternative material PE30 than PE70 tend to represent better. This implies that the replacement of 10% expansive admixture for PE30 is excellent

Gyeongryeongjeon has several aspects such as building for ritual ceremonie, Wonmyo and architecture of Jinjeon. As building for ritual ceremonie shows the phases of the times, thought, religion and international relations, the research of Gyeongryeongjeon has not only architectural but historical and cultural significance. Because Gyeongryeongjeon had a role of Taemyo and building for ritual ceremonie of Goryeo influenced building for ritual ceremonies of Joseon. we can also acknowledge the history of building for ritual ceremony with this study.

The creation and development of the city center in the process of social and economic function space, the highest intensity, which functions as a center where the population is concentrated. But while the growth of the city was concentrated in the center features are dispersed to other places in the city, the population distribution as the city does not function like the former will decline. Public institutions, especially the floating population of the city's urban escape reduction and urban land and buildings, including the decline of the economic decline has been the cause of the problem. Therefore transferred to the social need for public facilities grant a new feature of the existing recycling center circle deliberation needs to be resolved.

We focus on the urban type living-pod housings (ULPH) which adequately correspond to rapid change of the housing environment so as to respond to the housing needs of one or two person families. We suggest housing designs such as modular housing and/or container housing type of ULPH which show possibilities as the future prototype of flexible and extendible ULPH on the condition that we adopt the new concepts such ‘Plug & Play’, the Core and the Pods, Modular Construction and Space Swapping. We finally suggest two design prototypes of ULPH.

This study began with the unfortunate death of promising artist and try to find a solution to recover the identity of local culutre by proposing art center. In modern society. people hunger for culture, but the level of welfare is worse today. So this project is to make an architecture place to gather scattered culutere elements in the gongju old city, and these elements have a network by themselves. By studing the Gukgogae street and the case of art studio utilizing idle space, it was conducted identity in the way that enhansing rather than presenting a new model, If the 'Gongju art center' as art studio is settled down favorably, it will be positoned as a real 'art creation space' successfully combined traditonal place and creative workplace of ar t& culture. It provide satisfaction of dwellers' desire for culture enjoy and boosting up the community economy and promoting the string that connect ancient, modern and present age.

Steel moment frames with weak axis connection are used in domestic steel fields as a lateral load resisting system as well as strong axis steel moment connection unlike USA or Europe. However, these connection types have been frequently used in domestic steel construction fields even though researches on these connection types could be hardly found. Therefore, the main purpose of this research is to evaluate the cumulative energy dissipation capacity based on researches on steel moment frame with weak axis connections that had been performed by other researchers.

The purpose of this design thesis is to propose the 'Transformable Architecture' focused on the movie 'Transformer's autobots which transfers from vehicle to autobots. and suggests a plan for an exhibition space by applying the transformable structure system and the movable system like the autobots transfers. The elements of space or space themselves change physically and flexibly by increasing or decreasing. This idea can resolve the problem where the local area which has the shortage of exhibition space. and provide the temporary space which is event space for users.

This study analyzed the technical property of ultra high strength concrete pursuant to changes in superplasticizers and SF replacement rates with a view to reviewing the plan to use a superplasticizer containing CASB as an additive for enhancing strength, whose results are summarized as follows: For the unhardened concrete, it could be seen that the use quantity of superplasticizers to meet the target slump flow increased when using CASB, and its setting time was promoted when adding CASB, but the increasing of SF replacement rates in CASB had no big effect on its setting time. When it comes to the property of hardened concrete, both of its compressive strength and tensile strength increased more when using CASB than when using N, its self contraction property decreased more in case of C-8 than in case of N, and its self contraction length change rate increased more in case of C-0 than in case of N.

The purpose of this study was to examine the necessity of eco-friendly finishing materials and how to apply the materials in apartment housing. From a perspective of environmental conservation, Green Apartment Housing can be defined as a hospitably planned residential complex, which is designed to decrease environmental load of energy, resources, and waste. On the realization of eco-sound architecture, building envelope is not only a black curtain to block external environment but also a filter which connects the inside with the outside of a building. To apply eco-friendly finishing materials, pre-review for analysis of each raw material should be preceded on the premise that a related policy for eco-sound design has been formulated.

This study is to analyze properties which compare improved curing sheet with blue sheet in order to check the performance which is tensile stress. As results, it is confirmed that improved curing sheet(MP+BBS1 and MP+BBS1+MP) is better than the blue sheet at using field already. And the more edge distance increases, tensile stress increases regardless of test pieces type. Also, MP+BBS1+MP is the best tensile stress regardless of edge distance. But in case edge distance at 25 mm, MP+BBS1 is similar in tensile stress to MP+BBS1+MP. Synthetically, curing sheet improved by MP is analyzed to be available instead of the original because it is superior to tensile stress.

As various physical and psychological problems occurs, the focus of housing shifted to health from worth. These problems can be treated and prevented by changing architectural housing planning environment. In this research, Serotonin hormone concepts are applied for making healthy housing environments. Serotonin hormone functions as controlling emotion and feeling happy in human body. Exposed to certain environments or conditions like light, physical activity, mental-stability, natural-friendly life, brain in human produces serotonin hormone. This research extracts housing planning factor for the activation of serotonin hormone and arranges these factors to residential developments.
