朴鶴吉 동아대학교 공과대학 부설 한국자원개발연구소 1991 硏究報告 Vol.15 No.1
It is required that the method convert the dry method in wall structure being prior during a building construction. Therefore, this study introduced P.C pannel model investigates the basic research for the convertion of a construction structral method, the optimization of structural design, and environmental property. Conclusions obtained from the study are following : 1. As the wet method finds a fault in the industrial structure, construction property, environmental property, and the optimization of structural design at the present, it is necessary that the wet method convert the dry method. 2. As P.C pannel model suggested this study, developing and researching the efficiency of construction, is prior to the dry method, it is expected to obtain the guarantee of a superior space rate and a execllent construction, the criterion of high quality, the shortage of a term of works, and the optimization of structural design in architecture.

火災時 高熱을 받은 鐵筋콘크리트 기둥의 耐力特性과 解析(Ⅰ)
李成宰,朴鶴吉 釜山工業大學 1987 論文集 Vol.29 No.-
This study is to present the practical recommendations for establishing the approximate analytical method and fire-resist6ing characteristics of reinforced concrete column-which is composed normal concrete and mild steel reinforcement SBD24-which is affected from high temperature, through theoretical interpretation of the existing literature on this subject and an temperature, through theorretical interpretation of the existing literature on this subject and an actual experimental proof. The important factors which are concerned with establishing an approximate expression of stregth reduction are outlimed. The influence of high temperature on the material properties of reinforcement and concrete are reviewed. The results are as follow. 1. The strength reduction, for reinforced concrete column at high temperature can be established and obtained by numerical analysis method. 2. The strength capacity of fire-resistance in reinforced concrete column can easily be known to concrete reduction factor table of time dependence. 3. Relationship of fire-resistance time and covered thickness can be reasonably calculated. 4. This paper include hereafter problems second-order influential factors,which are involved in spalling, splitting and expension deformation.

角形鋼管 Beam-to-Column 接合部 耐力一變形 特性
朴鶴吉 동아대학교 공과대학 부설 한국자원개발연구소 1994 硏究報告 Vol.18 No.1
This paper has been researched in an attempt to estimate strength-behaviour characteristics of Beam-to-column connection between W-beam and rectangular hollow section(RHS) column. Ail yield line thee is applied to estimate yield strength of connection in this study. Stress concentration and strain distribution of the cruiform connections which β ratios of beam flange with to RHS range from 0.5 to 1.0 are analyzed by the analytical method of FEM. FEM gives good estimation for an actural connection stress-strain characteristics, but yiel line theory had some differences between the theory and actural behaviour.

I刑斷面의 Web Crippling과 Web Buckling에 關한 理論的 硏究
朴鶴吉 동아대학교 공과대학 부설 한국자원개발연구소 1984 硏究報告 Vol.8 No.1
This study is on the two phenomena which are the localized yielding and over-all bucking of the web plates, i, e,, web crippling and web buckling. Such situations arise when concentrated loads are applied to the shape sections(I,H,WF Type, and plate girder) of the beams, beam bearing supports, and column web for the reactions of beam flanges at the beam-to-column connections. In this paper a theoretical solution to determine the ultimate strenght was presented, and the estimative and analytical investigation for the design code(AISC)and the theoretical background was summarized. The principal findings and results of the study may be summarized as follows; 1. It is considered that the theoretical expressions adequately describes the actural condition. 2. AISC testing expressions are satisfied with force equilibrium condition, but those are unsatisfied with the mechanism and full plastic moment conditions. 3. The safety factor for the web buckling is lower than that of the web crippling at the beam-to-column connections in comparison with the plate girders.
