Slab-Band floor have been primarily associated with apartment house construction. A numerical analysis of the stress for this system used simpson's rule, and this method was compared with solutions by the slope-deflection method. In the results of a comparison, it was found that results of simpson's rule was almost same as that of the slope-deflection method. This paper had seen that Slab-Band Floor system was more economical about 5%∼10% than two-way slab system.

This study dealts with optimization for volume of spherical shell under axisymmetrical uniform load. The objective of the design is to minimize the volume of spherical shell. The only constraint is connected with the shell stability. The design variable is the central angle of curvature.

姜文明 慶北大學校 1983 論文集 Vol.36 No.-
In this paper Slab-Band Floor for doubly reinforced concrete was analyzed by applying Ultimate Strength Design Method. And Slab-Band Floor was divided into column strip and middle strip. Thus each part was optimized by Lagrange's Multiplier method and differential calculus. In this paper objective function means cost function contained steel cost, concrete cost and form cost. Also design variables are steel ratio and effective thickeness of each portion. And constraint was considered by ultimate bending moment, minimum tickness for deflection and minimum steel ratio.

This paper descrides on the optimum design of low-income apartment. The procedures of this study have the following steps : * For the structural analysis, the 15th storey frame systems were composed on the basis of a unit plan which is arranged with four household. * By ETABS-program, the bearing wall system and slab-band system were analyzed elastically. * The optimal problems were made by considering the objective function which minimize the construction cost of frame. * Constraints are the design limits defined by the ultimate flexural strength, the ultimate shear strength, the minimum thickness, and the minimun ratio of steel in accordance with ACI 318-89 Code. * Optimization is conducted by GINO ( General Interactive Optimizer) in case Utimate Strength Design (USD). * For the optimum Design of underground parking lots in the low-income apartment,the results of rahmen frame system were compared with those of slab-band system.

This paper describes the automatic assembly of stiffness matrix to the frame analysis. The transformation method of stiffness matrix assembly, equation (10), has the disadvantage of requiring a large amount of computer storage for the matrices [A] and [k]. This method is suitable only for hand calculations and is very suitable for a computer method. In the examples, it has seen that the results of this method is identical to the results of equation^(5).

본 연구는 온도상승에 따른 압축을 받는 I-형강 보의 플랜지와 웨브의 국부좌굴응력해석을 위한 컴퓨터프로그램과 항복파괴전에 I-형강 보의 플랜지와 웨브에 국부좌굴이 일어나지 않을 최적 폭-두께비를 구할 수 있는 최적알고리즘의 개발이다. 본 연구에서 사용한 고온에 있어서 강재의 응력-변형도 관계식은 EC3(Eurocode3) Part1.2(2000b)를 근거하였다. 본 연구에서 국부좌굴응력과 최적 폭-두께비는 항복응력, 플랜지와 웨브의 국부좌굴계수와 폭-두께비 영향을 고려하여 해석하였다. 그리고 본 연구의 컴퓨터 프로그램을 적용한 설계 예를 들었다. This study involves the development of a computer program to analyze the local buckling stresses for the flange and the web of I-beams under compression at elevated temperatures, and the optimization algorithm to analyze the optimum width-thickness ratios which does not occur their local buckling prior to yield failure. The high-temperature stress-strain relationships of steel used in this study were based on EC3 (Eurocode3) Part1.2 (2000b). In this study, the local buckling stresses and the optimum width-thichness ratios were analyzed considering the influences of the yield stress, local buckling coefficients and width-thickness ratios of the flange and the web. Design examples show the applicability of the computer program developed in this study.
