The effects of vertical component of earthquakes on torsional amplification due to mass eccentricity in seismic responses of base-isolated structures subjected to near-field ground motions are studied in this paper. 3-, 6- and 9-story superstructures and aspect ratios of 1, 2 and 3 have been modeled as steel special moment frames mounted on Triple Concave Friction Pendulum (TCFP) bearings considering different period and damping ratios. Three-dimensional linear superstructures resting on nonlinear isolators are subjected to both 2 and 3 component near-field ground motions. Effects of mass eccentricity and vertical component of 25 near-field earthquakes on the seismic responses including maximum isolator displacement and base shear as well as peak superstructure acceleration are studied. The results indicate that the effect of vertical component on the responses of asymmetric structures, especially on the base shear is significant. Therefore, it can be claimed that in the absence of the vertical component, mass eccentricity has a little effect on the base shear increase. Additionally, the impact of this component on acceleration is remarkable so the roof acceleration of a nine-story structure has been increased 1.67 times, compared to the case that the structure is subjected to only horizontal components of earthquakes.

장명등은 능묘의 능침 앞 중앙에 놓여 사자(死者)를 지키고 밝혀주는 상징적인 기능과 함께 뛰어난 조형성으로 능역을 장식하는 역할도 담당했던 중요한 석물로서, 석등의 한 범주에 속한다. 정릉 장명등은 조선왕릉 장명등 중 최초로 조성된 장명등이며, 조선 전 중기 왕릉 장명등 가운데 유일한 사각 장명등(四角長明燈) 형태를 이루고 있다. 대석, 화사석, 옥개석 형식이 기본적으로 사각을 이루고 있어 팔각 장명등(八角長明燈)형식과는 완연하게 구분된다. 하대석, 간주석, 상대석을 1매의 통석으로 마련하고, 화사석은 1매의 통석으로 전후로 화창을 표현하였다. 정릉 장명등은 고려 현 정릉 장명등의 전통을 그대로 따랐으나, 이보다 뛰어난 조형성을 보이고 있어 조선 개국 이후 최초로 조성되었던 왕릉 장명등으로서의 격조를 무리없이 보여준다. 본고에서는 정릉 사각 장명등 양식의 원류를 파악하는 데 연구 목적을 두고 고려 왕릉 장명등과 더불어 사각 장명등의 연원이 되는 사찰 사각 석등과의 비교 고찰을 시도하였다. 그 결과 고려 말 회암사지 지공선사 석등 및 나옹화상 석등, 조선 초 회암사지 무학선사 석등 및 청룡사 보각국사 정혜원융탑석등과 다음의 공통점들을 확인할 수 있었다. 첫째, 대석, 화사석, 옥개석 등이 기본적으로 사각을 이루고 있는 점, 둘째, 간주석이 낮아지면서 대석부분이 안정적인 형태를 이루는 점, 셋째, 화사석의 경우 대석 위에 양측으로 석재를 세워 자연스럽게 전후로 화창을 구성하는 방법, 넷째, 옥개석이 사모지붕 형태를 하고 있는 점 등이다. 한편 정릉 장명등에는 불교적 요소가 다분히 내제되어 있는데, 간주석의 삼주문(三珠文)표현이 그것이다. 삼주문은 밀교와 관련된 상징물의 하나로서, 우리나라의 경우 고려 불화 및 조선 초기 보살상의 보관에 표현된 예가 확인된다. 정릉 장명등은 이후 묘 사각 장명등 조성에 직접적인 영향을 끼치는데, 15세기 후반 이후부터는 점차로 정릉 장명등의 영향에서 벗어나 팔각 장명등 형식이 보다 많이 가미된 경향으로 변모해 나간다. 정릉 사각 장명등은 고려왕릉에서 조선왕릉으로의 능제 계승, 사찰 사각 석등 양식의 수용, 그 시대 불교사상의 반영 등 당대의 시대상과 문화의 흐름을 유추해 볼 수 있는 다양한 요소들이 담겨진 산 증거물로서 의의가 있다 하겠다.

This study summarizes the relations among $PM_{2.5}$ concentration, water-soluble ions concentration, metallic element Components characteristics and SPSS in negative ion and metallic element of $PM_{2.5}$ particle in Miryang.(By the urban area, the industrial complex area and the suburban area according to the season) $PM_{2.5}$ concentration of total 72 samples collected from 3 sites turned out to range from 3.47 to 34.7 ${\mu}g/m^3$, and the average concentration was the suburban area-the kin nup(16.00 ${\mu}g/m^3$) > the urban area-the roof of the old Miryang university(10.32 ${\mu}g/m^3$) > the industrial complex-Sapo industrial complex(10.29 ${\mu}g/m^3$). In particular, the suburban area had $PM_{2.5}$ concentration 1.5 times those of urban area, industrial complex. It was thought although the site was suburban and farm-side without pollutants around, it had a higher concentration value influenced by external factors including the brickyard, small-scale incinerator, driving range construction, construction on the Daegu-Busan express and the widening of the four-lane road between Miryang-Anyang nearby. As for water-soluble ions among $PM_{2.5}$ particle collected in Miryang area, $SO4_{2^-}$ accounted for 60% and $NO_{3^-}$, was 30% in spring and summer. And $NO_{3^-}$ accounted for 50% and $SO4_{2^-}$ was 35% in fall and winter. The AI value of metallic Components among $PM_{2.5}$ particle collected in Miryang area had a high value influenced by the apartment complex construction and the extension work of road. The industrial complex area had Zn concentration 3 times, and Fe concentration 2 times those of urban area and suburb area. When it comes to the relation with metallic elements in urban area, the highest coefficient of correlation was between Cr-Fe with 0.85, and Pb-Cd turned out in the reverse correlation. Among metallic elements, the coefficients of correlation between Zn and Cr, Mn, Fe, NI were high in industrial complex area. The highest coefficient of correlation was between Mn-Zn with 0.88, meanwhile Ni and Cu, Cd turned out in the reverse correlation in the suburb area. These coefficients of correlation are attributed to the difference in pollutant sources, rather than difference in pollutant and non-pollutant.

With the increasing demands of 3D spatial information in urban environment, the importance of point clouds generation techniques have been increased. In particular, for as-built BIM, the point clouds with the high accuracy and density is required to describe the detail information of building components. Since the terrestrial LiDAR has high performance in terms of accuracy and point density, it has been widely used for as-built 3D modelling. However, the high cost of devices is obstacle for general uses, and the image-based 3D reconstruction technique is being a new attraction as an alternative solution. This paper compares the image-based 3D reconstruction technique and the terrestrial LiDAR in point of establishing the as-built BIM of outdoor structures. The point clouds generated from the image-based 3D reconstruction technique could roughly present the 3D shape of a building, but could not precisely express detail information, such as windows, doors and a roof of building. There were 13.2~28.9 cm of RMSE between the terrestrial LiDAR scanning data and the point clouds, which generated from smartphone and DSLR camera images. In conclusion, the results demonstrate that the image-based 3D reconstruction can be used in drawing building footprint and wireframe, and the terrestrial LiDAR is suitable for detail 3D outdoor modeling.
