As social needs are increasing to minimize the occurrence of external effect due to urban development and to diffuse the benefits of development to surrounding areas, diverse cooperative planning methods are increasingly being discussed. In the long term, laws and systems need to be refined to support cooperative planning, but prior to such development, elements, procedures, and methodologies wherein cooperative planning in U.S.A cases could be implemented were examined to derive the alternative to and implications of cooperative planning that can apply not only to single administrative districts but also to complex boundary new towns being developed by various local governments. This paper surveyed and analyzed the cases of Wisconsin State of the U.S.A, thereby deriving the following implications. First, joint planning areas should be established within the boundary area of various local governments to establish cooperative planning areas in special areas such as complex boundary new towns, and to this end, urban planning means should be prepared. Together with such efforts, to boost the flexibility of cooperative planning, life sphere unit-based planning unit should be established, and a well-organized operation system to activate communities should be prepared. Also, revenues, generated through regional growth, should be distributed to individual local governments through joint tax according to the agreed-upon ratios, and as such, measures to share services and operate joint tax in small-size regions should be secured. Together with such efforts, to establish cooperative governance, measures to manage conflicts through the participation by stakeholders and arbitrators should be prepared from the planning stage, and measures for implementing cooperative planning at the level of basic urban planning should be prepared.

Residential Environment Improvement Project (REIP) which has started in 1989 and continued with 3rd government-supporting project in 2013 has lots of policy changes and related studies. However, the related researches have focused on residents resettlement into the project site, this paper is more interested in the residents stability than residents resettlement. So, this paper analyzes the changes of residents stability on the site of REIPs (with 3 groups of dwellers, removers and newcomers). We survey about understanding of those projects, each interior physical housing characters, housing cost, outside settlement characters. On the base of case analysis, we can conclude as follows: firstly, the residents are more young, higher educated, and higher income but not alter to household, barrier, occupation. Secondly, REIPs have some positive influences on physical conditions of housing and outside characters but negative impacts on housing cost. In case of newcomers, there are no changes of housing size and room numbers but higher housing cost, better outside settlement conditions.

This paper presents various attempts to secure the floor impact sound insulation performance on the dry floor system of steel framed modular house that lately attracted domestic attention. Test results show that in the condition of using dry floor system of D31(D32), the light-weight impact noise performance records the top level in the floor impact sound insulation performance grading system. the heavy-weight floor impact noise performance meets the minimum sound level limit in the floor impact sound insulation performance grading system that enacted regulation on housing construction standards.

An experimental program was initiated to investigate the structural capacity of PC (Precast Concrete) beam-column joints used for the underground parking structure. Static testing of 4 typical PC beam-column joints specimens was conducted. Specimens were designed to span a range of parameters typically encountered for such members, based on findings from the survey of existing PC joint details used in the construction fields in Korea. The specimens were four by their joint types and testing parameters. The specific structural behavior germane to each specimen, and general observations on overall member behavior as a function of the considered parameters, are reported. From the results of tests on four PC joints specimens, the beam-column joints of PC structure used for the underground parking building was found to have similar structural capacities when comparing to the cast-in-place concrete system.

The purpose of this study is to develop hybrid energy blocks with piezoelectric and electromagnetic induction method. The developed energy block is able to be applied to the housing and facilities in the city and is suitable to adjust the characteristics of facilities. To develop the hybrid energy block, we analyzed the characteristics and requirements of various energy block types and drew improvement and application method to develop energy blocks. We compared and analyzed the characteristics and performance of the prototype energy blocks and the developed hybrid energy blocks. According to result of the comparison and analysis, the developed energy block shows higher performance of 12.7 times for adding one vibration and 28.9 times for five consecutive vibrations than that of a existing prototype energy block. This is consistent with research purposes for W-level electrical energy production. Thus, the new energy block will likely be possible to apply to the housing and urban facility.

Passive energy dissipation systems for seismic applications have been under development for a number of years with a rapid increase in implementations starting in the mid-1990s in many countries. A metallic hysteretic damper has most commonly been used for seismic protection of structures in domestic area because they present high energy-dissipation potential at relatively low cost and easy to install and maintain. This paper presents an analytical case study of the effectiveness of isotropic hysteretic metallic damper(IHMD) called Kagome as a passive dissipative device in reducing structural response during seismic excitation. An eighteen-story RC framed apartment building is studied with and without IHMD. Results demonstrate the feasibility of these techniques for seismic mitigation. The inclusion of supplemental passive energy dissipation devices in the form of IHMD proved to be a very effective method for significantly reducing the seismic response of the building investigated.

Site coefficient and amplification factor of current domestic Seismic Design Code (KBC-2009) have no consideration for the domestic ground condition in which the base rock is normally placed within 30m form the surface. Accordingly, in this study dynamic centrifugal test and analysis for pile foundation into clay were achieved. and the response spectrums of free surface and basement were compared with each other. Within the period 1sec., the measured spectral acceleration of free surface and basement was bigger than the design spectral acceleration of SC and SD site. However the measured spectral acceleration of free surface and basement for the period over 1.5sec. was smaller than the design spectral acceleration of SC site. There was no severe difference of spectral acceleration according to the upper structure, embedded depth of foundation and free surface conditions. Consequently, normal domestic apartment housing for the period range over 1.5sec. could be design more economically applying these test result.
