It is the most significant point in the designing process to assume the initial cross sections of the structural members in structural calculation for building design This study is concerned with the determining of the initial cross section of beams and girders for optimum design in reinforced concrete structures. This paper is aimed at determining the optimum cross section size of reinforcement and concrete of beams and girders for economical structural design and simplicity of structural calculation. The results of this study could be· summarized as follows; (1) The initial cross section of beams and girders determined by the resistant moment is more reliable than that by the method of experience. (2) It is more economical, simplified and reasonable to sestet the cross section size of reinforcement, α_t and concrete, bd through reviewing the relationships b, d and α_t in the graphs, equations and architectural functional requirements of the beams and girders. (3) It is preferable increasing the strength of concrete to increasing the strength of reinforcement in reducing the beam depth.

황홍순 大田工業大學 1992 한밭대학교 논문집 Vol.9 No.2

The buckling strength of the welded Light Weight H-Shaped Steel columns has been investigated experimentally and analytically. Experiments have consisted of tension test, stub column test and long column test. The results of long column test have been compared with theoretical predictions based on the beam-column concept. And the re- sult of the test have been discussed to apply to the current design code. Finally, some recommendations have been presented for the design of this type of column in association with the SSRC column curves and the ECCS column curves.

黃弘淳 大田工業大學 1989 한밭대학교 논문집 Vol.6 No.2

This study concerned with the bending strength and deformation capacity and characteristics of Weld formed Light Weight H-Shaped Steel Beams under pure or 3-Point bending. Through this experimental test and analysis, the following conclusions were obtained. 1. Through the coupon test and Stub Column test, it was found that the section properties of Light Weight H-Shaped Steel Section was satisfied structural design code and specification. 2. The bending strength of Light Weight H-Shaped Steel Bens is related to slenderness ratio, and the increasing ratio of stress. 3. The deformation capacity of Light Weight H-Shaped Beam is expressed by eq. (3-4). 4. The bending strength of Light Weigh H-Shaped Beam under Pure bending and 3-Point Bending is Predicted by the numerical analysis on moment-curvature relationships and the test results.

PERT/CPM을 利用한 技術敎育의 敎育課程 構成에 關한 硏究

黃弘淳 大田開放大學 1985 論文集 Vol.3 No.-

This study is concerned with the development of curriculums for technical education. We need some technologists and engineers who have high-technology in the modern Industrial societies. Nowadays, with the rapid progress of the modern high-technology, the curriculums for the technical education need some Improvements in performing the education of the technologies. The moat Important things to plan the curriculums for technical education are the constitution of educational contents, sequences, periods, directions, and levels. And it needs to constitute educational resources: that is, educational persons, materials, spaces, equipments etc., systematically. In the view points of students, there are some problems of the continuity between the precedent teaching-learning subjects and the subsequent teaching-learning subjects, overlapping of contents of subjects, vagueness of times and credits of subjects in the curriculums for the technical education. In this respect, an attempt was made to improve and constitute the curriculums for the technical education by the method of PERT/CPM. As we can constitute the curriculums that the contents of subjects were gotten from analyzing of task for the technical education by the method of PERT/CPM, It is possible to perform the team-teaching, and we can realize the relationships between the schools and industries and get a lot of advantages.

黃弘淳,朴仁雨 大田産業大學校 1995 한밭대학교 논문집 Vol.12 No.0201

An Experimental Study on the Strength and Deformation of the Reinforced Steel Fiber Short Columns under Axial Compression This research is aimed to investigate the strength and deformation of the Reinforced steel fiber concrete short columns under uniaxial load. The main variables in this study are compressive strength of steel fiber concrete, tensile strength of boor bars, steel ratio hoop bars, and configuration of hoop bars. Fourteen specimens were tested and these experimental results were compared with one anothor and theorical analysis values. The resluts of this experimental study showed: 1. The strength of reinforced steel fiber concrete columns increased according to the increase of strength of steel and concrete. 2. The increasing ratio of the strength of reinforced steel fiber low density concrete columns is larger than that of reinforced steel fiber high density concrete columns. 3. The initial tangent of P-ε curve of high strength Hoop Bars is larger than that of Low strength of Hoop Bars. 4. The initial tangent of P-ε curve and strength of columns high restrained hoop bars were larger than those of low restrained hoop bars.

The inelastic lateral buckling strength of weld formed H shapped steel beams are evaluated under with the intermediate restraint condition. The testing results are compared with the numerical analysis using stub column curves based on the tangent modulus theory. From the result of study the restraint limit value in the inelastic range of mechanical properties of weld formed H shapped steel and the intermediate restraint effects are discussed.

This thesis aims to stuffy and analyze the strength and permeability of concrete in order to see the suitability in general structure in using water cooled blast furnace slag produced from the iron industry as a fine aggregate. Under the similar condition of workability, in the 14th day of curing period, there is the difference about 3.4% in compressive strength between the general concrete and water cooled blast furnace slag concrete, but in the 28th day of curing period, there is no big difference between them. the permeability relations of concrete is almost same in W/C 45%, 55% and in W/C of 65% water cooled blast furnace slag concrete is more permeable than general concrete. And the result of using mixedly water reducing admixture is that the unit volume of cement is reduced about 8% and 20% of permeability effect.
