  • In this study, I would like to inquire about the composition of oegi(外機) on the hip and gable roof. Oegi purlin compose the basic member of framework of a hip and gable roof in both sides roof, supporting the inside end of the side rafter. However, the oegi purlin is not simply used to form hip and gable roof. The effects of using oegi purlin have the advantages of spatial. The spatial advantages are the width of the toekan(退間) increases as the oegi purlin escapes from column row and to increase the ceiling height by becoming a point of staying the ceiling. That reflect the desire to expand indoor space due to changes in worship behavior. Oegi purlin was used not only for structural needs, but also for altering in indoor space due to the changing times.

  • This study is about the structure and transition of orthogonal design of palace architectures in Joseon Dynasty. The results are as follows. First, Changdeokgung and Changgyeonggung Palaces' corridors, and their architectures seen in the Court Documentary Paintings have early Joseon style in the corner-connections. Their roof shape in the corner is gable roof. Generally, gable roof has direction. Besides, it is easy to extend gable sides. Second, Corridor of Gyeongbokgung Palace has hipped and gable roofs with corner eaves. It was popular during the late Joseon Dynasty. On the other hand, it is impossible to extend any sides of those roofs since they have roof faces in their four sides. Instead, they have completeness. That's why their aesthetic appeal exhibits more pleasing than gable roofs. Third, corner-connections of palace architecture shows evidences and traces of the transition from gable roofs meeting at right angle in the early Joseon to hipped and gable roofs meeting at right angle with corner eaves in the late Joseon. Also, the corner-connections with corner eaves were usually used even in the attached architectures.

  • It is difficult to build a hipped and gable roof in slender rectangular type due to restraint in variation of lateral length caused by gongpo arranged on the side, purlin space and the form of gable part and aesthetical effect of chunyeo maru. Against this backdrop and with the assumption that this phenomenon is more apparent in roofs of three-bay-kan Buddhist temples with the hipped and gable roof among national treasure Buddhist temples, this study has aimed to prove that a roof can be built in a less slender rectangular type than that of flat form and to present the building methodology and found the following findings. First, The ratio of lateral to longitudinal length of the roof has been adjusted by protruding the chunyeo and the method of adjusting the ratio of lateral to longitudinal length of the roof is considered to be determined depending on the availability of woods to be used in chunyeo. Second, in order to symmetrically arrange the edge of the roof, which is critical from the perspective of construction morphology, the chunyeo angle has been intentionally adjusted to reduce the gap of length between the front roof and the lateral roof. To sum up, the characteristic of the hipped and gable roof, which is difficult to be built in slender rectangular type, is more clearly shown in the roof and it is identified that the length of the front roof and the lateral roof has been intentionally adjusted to achieve the symmetrical arrangement of roofline of the roof edge.

  • The purpose of this study is to classify roof styles about high-rise apartment complexes in these days. Specially, it is focused on those in Daegu city. It has analyzed for 75 apartment complexes in Daegu city. Those complexes are all over 300 houses each and were built from 2004 to 2007. Generally, roof styles about high-rise apartment complexes are classed as a flat roof style and a slope-sided roof style. Types of the flat roof style were divided a flat roof style and a eyebrows roof style. And, types of the slope-sided roof style were divided a single slope-sided roof style, a gable roof style, and a hipped roof style. The curved roof style didn't show up at these cases. According to this study, the slope-sided roof style including the gable roof style was revealed the most common roof style about high-rise apartment complexes in Daegu city from 2004 to 2007. Among 76 cases of roof styles, the number of the gable roof style is 52, and the number of flat roof style is 18. Each roof style was changed for more decorative shape. Specially, in case of the flat roof style, 17 cases for 18 cases are built as a decorative flat roof style. and, 15 for 52 gable roof style cases are built as a decorative style, too. According this case study, we are able to know that the sort of roof style was advanced variously and decoratively, and the shape of roof style was combined more than 2 decorative factors. The roof style of high-rise apartment complex in future will be more various and decorative than this time and will be develop compositively.

  • The paper addresses the suitability of wind pressure coefficients specified in contemporary design standards and codes of practice for gable roofs of intermediate slope (roof angle $10^{\circ}-30^{\circ}$). In a recent research study, a series of low building models with different roof slopes in this intermediate range were tested in a boundary layer wind tunnel under simulated open country terrain conditions. This was different from the original study in the 70's, which produced the current provisions on the basis of a model tested only for a single roof slope (4:12) in this range. The results of the study suggest that a modification to the American wind provisions would be warranted to make them more representative of the true local and area-averaged wind loads imposed on gable roofs of intermediate slope.

  • This study investigates the types and spread of framed structures of gable roofs meeting at right angle showed in old architecture and documentary paintings of houses, which were well liked in the early Joseon Dynasty. The conclusions of this study were as follows. First, the framed structure of gable roof meeting at right angle can be divided or recognized in 4 types according to their structure's size and purlin's position. Three of those types were noted to be in Seoul. Second, the framed structure of gable roofs meeting at right angle begun from the awareness of their independence from one another. Each space was divided based on their functions. Therefore, it could be extended in various forms, not only in the square plan physique but also in many different forms. And allowed free plan configuration regardless of column layouts or size of structure. Third, 5 purlins and 3 purlins crossing structure were preferred in Han-yang, the early Joseon Dynasty. It is related to the specific construction conditions of urban houses, such as the slope of land, limited land area, and economic power. Fourth, urban housing techniques were diffused throughout the country by officials who lived in Kae-gyeong and Han-yang at the end of Goryeo and early Joseon Dynasty. In other regions, framed structure of gable roof meeting at right angle households decreased, but in some regions of Gyeongsang-province, framed structure of gable roof meeting at right angle has maintained with Staggered purlin.

  • This aim of the study is to investigate the plan and elevation types of existing way stations built in the early 20th century Korea, focused on Choong-ang, Donghae-nambu, and Kyung-jeon line of the railroad tracklines. The plans and elevations are drawn up and analyzed based on literature data and aerial photographs through the survey. These way stations are classified into various types by room layout and front elevation. The basic plan types are composed of waiting room, station service room, and administration. The station service room has a train operation room in the projecting part of corner. This room has windows on every side to see in and out of train. There are the enlarged, extended waiting room types, and linear types in the other plan types. The waiting room is lied on the right side, and has a gable roof in elevation. The elevation types are classified with side and centralized, and so on by the placement and shape of gable roofs. The basic elevation types have gable roofs in sides lied on the waiting room, and these types are transformed into centralized types by extension of waiting room The others are the linear types without gable roofs and the unusual roof types in appearance.

  • This study deals with the contemporary rural housing with special reference to the roof types/materials and the outer wall materials in Ulleungdo Mountains. The most frequent roof type of rural housing is the hip-and-gable roof type(42.1%); and the next, the gable roof type(25.8%). For the roof materials, the precoated steel plate(69.1%), the asphalt shingle(11.8%), and the cement(10.7%) are the most frequent but the roofing tile and the artificial slate are not used. And for the outer wall materials, the cement(27.5%), the siding(21.3%), the corrugated galvanized iron(16.8%), and the lumber sheet(6.7%) are the most frequent. It is the hip-and-gable roof housing type with the precoated steel plate(roof materials)(41%), or the hip-and-gable roof housing type with the precoated steel plate(roof materials) and the cement(outer wall material) (18.0%) that is the most frequent type of rural housing in Ulleungdo Mountains. For the roof/wall materials, the ratio of the corrugated galvanized iron is high probably due to the relatively low cost of transport, and the ratio of the roofing tile, the artificial slate, the red brick, and the building stone is very low probably due to the relatively high cost of transport.

  • This paper compared ventilation performance between the sound roof tunnel with flat roof and the sound roof tunnel with gable roof. The ventilation rate of the sound roof tunnel is calculated by natural ventilation rate plus ventilation by vehicle. The roof type is divided by the shape of the roof and the ventilator location on the roof. The results between calculation and CFD on the ventilation rate are almost alike. The ventilation rate on the flat roof is $558.4\;m^3/s$ with mid-ventilator and $496.8\;m^3/s$ with left-right ventilator. The ventilation rate on the gable roof is $653.2\;m^3/s$ with mid-ventilator and $611.6\;m^3/s$ with left-right ventilator. The ventilation rate of soundproof with gable roof is higher than that with flat roof. The ventilation rate and with mid-ventilator is higher than that with left-right ventilator the soundproof roof. Therefore, the ventilation performance of soundproof roof depends on the roof shape and ventilator location on the roof.

  • The low-rise buildings with gable roofs are commonly used in a number of industries. In order to study the characteristics of peak external pressure coefficient on low-rise buildings with gable roofs, wind-tunnel test have been carried out. Wind-induced pressures were measured simultaneously at many points on wind-pressure models, typical of simple low-rise buildings with gable roofs, which have seven different roof slope with constant width(D), height(H), and length(D). The pressure measurements were made in one kind of turbulent boundary layer, which simulated the natural winds over typical suburban terrains at a geometric scale of 1/150. The results indicate that peak external pressure coefficient on the roof and wall edges were increased. The results compared with wind standard of KBC-2005 and standards of various nations. The comparative resultant, experimental result appeared very similar at AIJ-2004. But the results were somewhat larger then wind standard of KBC-2005.
