본 논문은 구조물의 기초지지력에 안정성 평가를 위해서 연구되었다. 구조물의 하부에 설치된 기초의 저면은 지반과 접촉하게 되는데 지반유실 및 기타원인으로 인해 기초와 지반의 접촉면 일부분이 손실되었을 때 접촉비율에 따라 나타나는 지지력안정성을 분석하기 위해서 시행되었다. 이를 위해 기초저면과 지반의 접촉비율을 정량적으로 조절하여 수치해석 및 모형실험으로 지지력 거동을 분석한 결과 기초저면과 지반의 접촉율이 75% 이상일 경우에는 기초의 지지력이 크게 저하되지 않는다는 지지력 안정성 기준을 확립하였다.

Full scale size model tests of the top-base foundation was performed in siwha marine clay and the site measurement results were compared with the analytical results from finite different programs, FLAC-2D to investigate the behavior of top-base foundation. The stress distribution obtained from the numerical analysis for the various types of foundation were compared and analysed during the application of allowable load as well as yield load. It was found that the top-base foundation prevents the lateral deformation of soft ground and stress dispersion effect to reduce the surface settlement, and that the foundation creates uniform stress distribution around it, therefore increasing bearing capacity.

The bi-directional high pressure pile load test(BDH PLT) which is a kind of pile load tests was conducted to find out a reasonable design procedure of large-diameter drilled shafts of large-size building structures. The behaviors of bearing capacity and settlement of the large-diameter drilled shafts were analyzed and the results obtained from BDH PLT were also compared with those obtained from the equations suggested in the specification. In case of the reasonable design procedure adopted, the construction cost could be saved at least 15 ~ 28%. It could be concluded that BDH PLT should be needed for the foundation construction cost reduction of the high-rise building structures.

The purpose of this study is to provide for the basic data useful to the effective production and marketing of the foundation garment befitting adult women's shapes and preferences, and thereby, help them improve their apparel life. For this purpose, 563 Korean women aged between 20-59 were sampled to survey their recognition and actual wearing condition of foundation garments and positively identify the factors affecting the practices and thereupon, determine the correlations among them by age group. The raw data of this study is processed by SPSS Win(10.1) and analyzed by using frequency, percentage, $x^2$-test, ANOVA, Duncan-test. The most of adult women were aware of their foundation size and the absolute majority of them wore brassieres, while a half of them used the girdles. The adult women had 5.7 Brassieres and 2.2 Girdles. The use of the foundation depended much on user's age or seasons. They had begun to wear Brassieres at their age of 15 on an average and Girdle around their age of 19 depending their individual needs. It has been found through this study that adult women's is actual wearing condition of foundation garments differ by age group, which may well suggest that foundation production need to consideration this age-wise practices when setting up their foundation production and marketing strategies.

In this paper, the behaviour of shell foundation was studied. In order to perform this study, three studies such as theoretical, numerical and experimental programs were performed. In the theoretical program, the general shallow foundation theories and failure mechanism developed by Terzaghi, Mayerhof and others were reviewed and compared. Based on the previous shallow foundation behaviour, the shell foundation theory was developed using the upper boundary theorem. In the numerical study, the 2 and 3 dimensional FEM simulations were carried out using an uncoupled-analysis approach. From the analysis results, the adequate depth of shell foundation was evaluated. It was also evaluated the bearing capacity according to the shell angle ($120^{\circ}$, $90^{\circ}$, $60^{\circ}$). In the experimental study, the laboratory model tests were carried out for five cases of different foundation shapes including the rectangular and circular foundation in order to verify the theoretical and nemerical study. According to the results of this study, the bearing capacity of shell foundation was theoretically about 15% larger than that of general foundation. However, in the model test, the bearing capacity of shell foundation was about 25 to 30% larger than that of general foundation. In the case of shell angle, the maximum bearing capacity of shell foundation shows when the shell angle of foundation was $60^{\circ}$. In addition, Even if the shell foundation has the various advantages compared with the general foundations as described above, the practical verifications in full scale size will be necessary to use in the field and will be helpful in the technical development of other special foundations.

This study was conducted to investigate the relation between clothing pressure and subjective sensation exerted by foundation. Nineteen females volunteered as subjects. Experimental foundations were brassiere with 70B, 70C, 75B and 75C size which were widely distributed in pilot test and two types of girdle of which size were 64, 70 and 76. Clothing pressure with an air pack system and subjective sensation were measured at 5 points in brassiere and 7 points in the girdle. As the result of this study, brassiere's band and girdle's waist line, of which clothing pressure are high, is needed to improve. Generally the more pressure makes the more tightness, however, in some regions more or less pressure can give comfort. The tightness rating may not only related to clothing pressure, but also related to factors such as body size, body fat, resilience of muscle and bone structure. Other subjective sensation such as tactile feeling, hot/wet feeling, etc. in addition to the study with consideration of these factors could be used in future research to evaluate the effectiveness of foundation.

Bridge foundation failure considering the effect of local scour around pier foundations under hi-directional seismic excitations is examined in probabilistic perspectives. The seismic responses of bridges with deep foundations are evaluated with a simplified mechanical model, which can consider the local scour effect around the deep foundation in addition to many other components. The probabilistic characteristics of local scour depths are estimated by using the Monte Carlo simulation. The probabilistic characteristics of basic random variables used in the Monte Carlo simulation are determined from the actual hydraulic data collected in middle size streams in Korea. The failure condition of deep foundation is assumed as bearing capacity failure of the ground below the foundation base. The probability of foundation failure of a simply supported bridge with various scour conditions and hi-directional seismic excitations are examined. It is found that the local scour and the recovery duration are critical factors in evaluating the probability of foundation failure. Moreover, the probability of foundation failure under hi-directional seismic excitations is much higher than under uni-directional seismic excitations. Therefore, it is reasonable to consider hi-directional seismic excitations in evaluating the seismic safety of bridge systems scoured by a flood.
