The tensile structure system is a system that is composed with tensile members There are tension main system, vector system, and supported bending system, which have various tensile structure formations In this paper, for architectural planning, the composition elements and the composition pattern that have an effect on the architectural characters was Investigated In tensile structure system Thus, It was examined that the composition clements are tension member, profile shape, anchorage, arrangement and stabilizing And each tensile structure formation represents the typical architectural characters that are classified into three categories as these elements is composed One is the form developable type that the composition of structure member influences the design of exterior form, another is the general adoption type that there is no structural restriction in form and space, and the other is the large-unit space type that large space composition is obtained with respect to the dosed plan type For the extraction of the tensile structure characteristic, composition elements and tensile structure formations that are corresponded to these type groups have shown as the composition pattern

이주나,Lee, Juna 한국교육시설학회 2019 敎育施設 Vol.26 No.5

School gymnasium is a multi-purpose large space building for various events and physical education activities, and is a facility that requires an approach to the desirable structural design, besides mechanical problems of structure against loads. For the integrated structure design concerning the architectural features, the major considerations of gymnasium planning that are the internal and external shape of the gymnasium, the space scale with structure members, the structural efficiency by members weight reduction and openness of the gymnasium space will have to take into account in the structural planning. From this point of view, the several cases of the school gymnasium were investigated and the parametric analyses were performed to the models using the various structural system. The parameters were the composition elements of structure system that are profile of structure, rigidity of member, connection and anchorage and stability. At the result, It was presented that the profile of structure member was the most influential factor to structural efficiency and the effect of the form and space of gymnasium. Also the design informations of structure design having the various feature of form and space were presented for the initial gymnasium planning.

들림형 보구조는 휨재와 뜬지주, 스트링으로 조합되는 구조로서, 스트링에 PS력을 도입하여 휨재의 응력과 변형을 조절함으로써 구조능력을 높이는 구조시스템이다. 기존의 연구결과와 실사례를 조사하여 들림형 보구조의 특성과 구조계획시 구성방식을 파악하였다. 그 결과, 연력도형의 보의 형상 및 높낮이 그리고 스트링의 sag설정, 평면배열, 뜬지주의 수와 구성이 설계인자로서 고려될 수 있음을 파악하였고, 실사례와 구조적 거동의 연구고찰을 통해 그 설계인자의 세부 구성방식을 나타내었다. 또한 들림형 보구조는 큰 부가하중이 작용할 때의 구조부담을 줄이기 위하여 부가하중에 대해 별도의 저항 메카니즘을 고안함으로써 구조효율을 높일 수 있는 방식이 고려될 수 있음을 보였다. Beam String Structure is a structure system that is composed with beam, strut and string, and the structural capacity of this structure system is enhanced by introducing prestress force in string and controling the stress and deformation of beam. Researching on the established studies and examples, character and composition methods of Beam String Structure was investigated. At the result, It was examined that the design elements of the system are shape and rise of beam, sag of string, plan arrangement and the composition and number of strut, in addition, detailed composition methods of the design elements were represented. Also, it was showed that the method to form the individual mechanism against additional load can be employed in order to reduce stress of Beam String Structure under the heavy additional load.

In order to figure out the usability of various timber structures in the educational facility, the recent timber structure examples published in the Japanese architectural magazine, 'ShinKenchiku' over the past five years were surveyed. As the results, timber structures were presented in many cases of nursery schools and kindergartens overwhelmingly, and they also used in various school buildings, university facilities, and the roof structure of the school's gymnasium, with intention of having the differentiated design and space features. The examples show that span 6 to 10m is generally used with flexure structure system and flexure+compression structure system added the strut as compression members. In addition concerning stability, it was founded that the struts have an stability effect in the flexure+compression structure system, and flexure structure system examples using semi-rigid joints have open spaces liberally in two-way direction for about 9m span. For large spaces structures with span of 15~20m or more, the various structural system such as suspension structure, truss, flexure+compression, etc. was designed to overcome the material limitations of timbers and to make an design effect in structure system.

이주나,Lee, Ju-Na 한국공간구조학회 2009 한국공간구조학회지 Vol.9 No.2

스팬 30m 이상을 갖는 건축물로 한정하여, 1960년대 이후 건립된 국내 공공 대공간 건축물의 발달과정과 건립특성에 대하여 연구하였다. 국내 대공간 건축의 용도와 규모의 현황을 살펴보고 구조방식이 건립된 건축물에 미치는 영향을 살펴보고자 한 것이다. 연구결과, 1980년대-90년대에는 스팬 40-70m 규모의 체육시설이 집중적으로 건립되었으나 2000년 이후에는 용도가 다양화되면서 대규모의 컨벤션센터 건립이 다수 이루어지고 있는 것으로 나타났다. 또한 초기 독특한 구조형태와는 달리 80년대에는 입체트러스가 보편적으로 활용되었고, 2000년 이후에는 형태효과를 고려하여 구조체를 고안하거나 새로운 구조시스템을 활용하는 시도가 보여지고 있다. For the large space buildings since 1960s in Korea spanned more than 30m, the establishment feature and the development process were examined. As the Results, physical facilities with 40-70m span were mainly established in 1980s-1990s, but large scale convention centers have been establishing after 2000s as the used of large space buildings are varied. Also, a space frame has been generally used in 1980s while the unique structural shapes were builded in the early age(1960s), the structural design with concerns a form and using various structural systems have been attempting after 2000s.

이주나 한국공간구조학회 2016 한국공간구조학회지 Vol.16 No.1

This study analyzes the four composition elements : profile, anchorage and connection, material and member rigidity, stability, as the main composition design elements of flexure structure systems, in order to explore possibilities for more various structure designs in architectures with flexure structure system. It also examines typical design methods that use the mentioned four composition elements. At the results, this research presents an understanding of the differences between funicular shape and non-funicular shape and mechanical features of the shapes in the profile element, regarding to the ratio of rise height to span length(f/l). Also, the typical design methods are presented for the designable usages of the hinge joints and the fix joints, and for the applications of member rigidity expressed by the index of the ratio of member depth to span length(d/l). And it was presented that connection styles, addition of brace members, placement of shear walls are the main design methods in the stability element. This data would be useful to architectural designs concerning integrated design with structures.

이주나,박선우,박찬수 한국공간구조학회 2004 한국공간구조학회지 Vol.4 No.3

구조시스템은 역사적으로 발달해온 기술적 배경에 따라 건축에 사용되었고, 구조의 역할도 변화되어 왔다. 그러므로 다양한 구법으로 이루어지는 연성구조시스템의 건립사례와 시기에 따라 건립된 규모를 조사함으로써 여러 연성구조형식의 a성을 고찰하고 연성구조의 전개방향을 모색하였다. 그 결과, 연성구조시스템은 초기에 여러 케이블구조로 발달하기 시작하였으나 1970년대 이후부터는 막구조가 주로 사용되고 있는 것으로 나타났다 또한 초기의 케이블 구조시스템들은 대공간 건축에 주로 사용되었으나, 1970년 이후에는 중소규모의 건축물에 사용되는 경향이 있으며, 격자형 케이블구조나 공기막구조 그리고 돔 형식의 들림형 하이브리드 막구조가 대형공간으로 발달하는 경향을 보이는 것으로 나타났다. Structural systems have a lot of architectural meaning concerning historical context of structural technology. Therefore, surveying constructed examples and their constructed year, the character and development of various formations of structure systems with non-rigid member were investigated. At the result, the early modem structure systems with non-rigid member were made up from the cable structures, then membrane structures have mainly used after 1970's. The early structural systems had intended to make the large scale space, after 1970's, they have been adopted into the smaller scale space structure, and cable net structure, pneumatic structure and dome typed hybrid membrane system tend to compose the larger scale spare structure.
