        북미와 유럽 등지에서 주거용 주택소재로서 폭넓게 사용되고 있는 구조단열패널(SIP)의 구조적 성능을 평가하기 위해 면내전단하중 시험을 수행하였다. 국외의 경우, 구조단열패널의 기준과 관련된 연구들이 다양하게 진행되었다. 하지만, 국내의 경우, 구조단열패널에 대한 기준은 마련되어 있지 않으며, 성능평가와 관련된 연구는 극소수이다. 본 연구에서는 구조단열패널을 내력벽으로 활용하기 위한 구조성능평가 실험을 수행하였으며, 벽체에 개구부 설치 후 면내전단하중을 가력하였다. 실험체의 크기는 2,400×2,400㎜이며, 변수로는 개구부의 크기와 개구부 보강방법이다. 실험체의 수량은 총 8개이다. 개구부가 있는 구조단열패널의 구조 해석을 수행 하였다. 해석 결과는 구조 실험 시험 결과와 비교하였다. 이를 통해 구조단열패널의 구조 거동을 예측할 수 있는 해석 모델을 완성하였다. 개구 크기를 변수로 하여 면내전단하중을 받는 구조단열패널의 거동을 유한 요소 해석을 통해 분석하였다. 연구를 통해 구조단열패널의 최적 개구부 크기를 제안한다.

        The office building more than 3,000㎡ of the total floor area should be needed to improve the energy efficiency based on government's recommendation. In this study, the new composite panel with structural function is conducted to check the thermal conductivity for application of exterior wall. The thermal transmittance was calculated by dynamic analysis to consider the thickness of insulation only per locations based on design criteria. The simulation program for the analysis was used TRISCO Radcon module, which has a function of a steady-state 3-dimensional heat transfer analysis.

        Eccentric axial load tests were carried out to investigate the structural performance of the SIP (Structural Insulation Panel), which is widely used as residential type in Europe and North America. Outside the country, design standards for SIP have been prepared and related research has been carried out variously. However, in Korea, the research on the performance of the structural insulation panel is very small, and the related standard is not provided. In this study, the eccentric axial load was applied after the opening was installed to utilize the structural insulation panel as the structural wall. The size of the test specimen was 1200 × 2400㎜. The number of test specimens was 6, and the size of the openings and the reinforcement method around the openings were used as variables.

        In this study, the structural analysis of the structural insulation panels with openings was carried out. The analytical results were compared with those of the previous structural performance tests. The structural behavior of the structural insulation panels subjected to eccentric axial load with the opening size, installation direction as parameters was analyzed through finite element analysis. Through this, we propose an optimal opening shape suitable for the structural insulation panel.

        This project is mainly related to evaluation of total energy consumption of low energy house, the exterior envelope of which was wholly composed of structural insulated panels(SIP). The U-value of applied SIP was in the range of 0.189 to 0.269W/㎡․K and the U-value of pair glass from 0.78 to 1.298W/㎡․K was applied for window dependent to its function respectively. For comparison of total energy performance, the energy simulation for pilot house was performed to compare with the control house having insulation criteria of Korean building regulation in 2009. Based on simulation of dynamic energy performance, the pilot house saved 48.3% of annual energy consumption while the control house in 2009 consumed as 85.7GJ/y. In case of heating, the result showed that the energy saving ratio amounted to 76.7%. For CO₂ emission, the pilot house diminished approximately 35.4% from 6,208.4kgCO₂ to 4,009.2kgCO₂. In payback period to early investment, it was analyzed the pilot house took 7.8 years, when the low energy house built by other insulation method with same thermal perfusion took 11.5 years. From this result, it is considered that the SIP is more effective, economic to Green Home application.

        Structural insulated panels, structurally performed panels consisting of a plastic insulation bonded between two structural panel facings, are one of emerging products with a viewpoint of its energy and construction efficiencies. These components are applicable to fabricated wood structures. In Korea, there are few technical documents regulated structural performance and engineering criteria in domestic market. This study was conducted to identify fundamental performance of both monotonic load and quasi static cyclic load for SIPs in shear wall application. Static test results showed that maximum load was 44.3kN, allowable shear load was 6.1kN/m, shear stiffness was 1.23 M N/m, and ductility ratio was 3.6. Cyclic test was conducted by two kinds of specimens : single panel and double panels. Cyclic test results, which were equivalent to static test results, showed that maximum load was 45.42kN, allowable shear load was 6.3kN/m. Furthermore the accumulated energy dissipation capability for double panels was as 2.3 times as that for single panel. From performance of structural tests, it was recommended that the allowable shear load for panels was at least 6.1kN/m.

        Structure Insulated Panel (SIP) is an wooden structure material with which structure and insulation functions are satisfied. Hence, it would be a cost-effective model to implement low energy house which has higher insulation and structure performance and which the wall thickness is able to be reduced. In this study, performance of thermal insulation and fire resistance were evaluated in order to verify applicability to low energy house. Fire resistance test is performed on vertical load bearing members for partitions, and the test results satisfy one hour of fire resistance condition according to KS F 2257. The members include two layers of fireproof gypsum board with thicknesses of 12.5mm attached to SIP. Thermal insulation performance is satisfied with the 2012 standard (0.225W/㎡·K). As the performance of resistance and thermal insulation are satisfied, SIP is expected to be applied to low energy building materials. In the future, the structural safety will be confirmed by structural performance and seismic performance test and the guidelines for distribution will be drawn up.

        Structural insulated panels, which are structurally performed panels consisting of a plastic insulation bonded between two structural panel facings are one of emerging products with a viewpoint of its energy and construction efficiencies. These components are applicable to fabricated wood structures. By now, there are few technical documents regulated structural performance and engineering criteria in domestic market. This study was conducted to suggest fundamental reports such as racking resistance, axial capacity, transverse load capacity, and lintel load capacity for SIPs. Test results showed that maximum load was 44.3kN, allowable load was 14.7kN for racking resistance, and that maximum load was 137.6kN, allowable load was 37.4kN/m for axial compression capacity. For transverse load capacity, test results showed 10.3kN/㎡ of maximum load, 3.4kN/㎡ of allowable load. For lintel load capacity for SIPs dependent to lengths, allowable loads were 20.4kN for 600㎜ long lintel, 23.9kN for 1,200㎜ long lintel, 19.3kN for 1,800㎜ long lintel, and 2,400㎜ long lintel had 14.1kN of allowable load. In the near future, when the allowable load for wall application is established, SIPs is considered to substitute the existent post-and-lintel construction to bearing wall structure.
