In line with the worldwide trend toward the protection of natural environment and economic concerns, the steel framed house is suggested for the next industrialized generatiov. In Korea, untrustworthiness of concrete structured apartment has led to the development of alternative building material and technology. POSCO has constructed the model steel house to assess the marketability of steel framed house in Korea. To collect basic data required to design the steel framed house suitable to Korean life pattern and housing needs, professional evaluation of model steel house was conducted. The goal of this study is to propose alternative plan and ideas on the interior space planning based upon the evaluation from women housing professionals. Our analysis reveals that the habitability of steel house is equal or superior to that of traditional houses. But in the interiior sapce planning, the certain aspects of steel houses is not suitable to Korean likfe style: the lack of storage space and utility space, inflexibility of plav. We conclude that given its cost efficiency and environmental concern, steel house has potential to take an important part in future Korean housing.

Judging from recent aspects of lift, Housing of diverse types are emerzing as the interest of housing quality takes a growing with advanced life-cycle, varity of dweller needs and high-grade consuming patterns. This study is to explore more positive design method of steel-framed house through analysis about the decorative properties, choosing steel-framed house designed by domestic architects after 1990. In conclusion, as actively making use of merits of steel-framed house and making up its faults, it is suggested as a possibility of modern future-types housing

This study proposes a method of generating steel house shop drawing in an automated design method, reducing construction manpower and period. With one hour fire-resistant approval code, reflecting work ability and efficiency, steel-framed house market is expected to extend from one or two story house to multi-purpose facilities up to four story height. More models have been constructed in this system than the first appearance of fire-resistant approval in Korea in 1997. Also, cost estimation of components such as frame walls, roof trusses and floors is obtained with shop drawings. Also, the lack of suppliers of steel framed house shop drawing and unstandardized drawing method get constructors have difficulty in understanding its design. In steel framed house industry, shop drawings are essential part in building and constructing framework and they have major effects on construction deadlines and expenses. By exploring method of shop drawing automation, this study aims to optimize work flow with a standardized drawing method. The proposed system can be applied to manufacturing automation in domestic industry of factory-built panelizing method in the near future.

The Zhuhai Opera House has an external structure consisting of a type of spatial steel, where the stress of steel elements varies with the ambient temperature. A structural health monitoring system was implemented at Zhuhai Opera House, and the temperatures and stresses of the structures were monitored in real time. The relationship between the stress distribution and temperature variations was analysed by measuring the temperature and stresses of the steel elements. In addition to measurements of the structure stresses and temperatures, further simulation analysis was carried out to provide the detailed relationship between the stress distributions and temperature variations. The limited temperature measurements were used to simulate the structure temperature distribution, and the stress distributions of all steel elements of the structure were analysed by building a finite element model of the Zhuhai Opera House spatial steel structure. This study aims to reveal the stress distributions of steel elements in a real-world project based on temperature variations, and to supply a basic database for the optimal construction time of a spatial steel structure. This will not only provide convenient, rapid and safe early warnings and decision-making for the spatial steel structure construction and operation processes, but also improve the structural safety and construction accuracy of steel space structures.

This article examines that how in-house subcontract has been introduced and developed in metal industry in 1970s, focusing typical workplaces in steel industry. That was essential for the capital to insure control mechanism for large number of laborer because of mobilizing a large scale of capital in industrialization of heavy metal industry. In case of Pohang steel industry, this necessity was fulfilled by introduction and imitation of Japanese personnel management by being included of Japanese economic hinterland. This was embodied in both constructing internal labor market for regular workers and introducing in-house subcontracting system for contingent workers at workplaces. This was exceptional comparing in-house subcontracting system in Korean steel industry with in-house subcontracting system in advanced economies, because of disappearing in-house subcontracting system by making internal labor market. And this was closely linked by late development of Korea. Implications of Pohang steel company's case are as follows : first, late development effect in formation of employment system, second, in linking informality of Korean employment system. This implications mean that in-house subcontracting in steel industry is structured as mechanism for personnel management in large factory being influenced by industrialization of heavy industry. In this point, improvements which include wide economic solution beyond labor solution for present problem of in-house subcontracting system is desirable.

Precast Concrete apartments were main stream of domestic industrialized housing around 90's , and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel stud and Unit Box have their own merits an demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the Open System basis. In this study, the design standard for Unit house will be established coping with the established preparing standard for design specifications defined by Architectural Law and Promotion Law of Housing Construction. That is for design standard of industrialized private housing on the Open System basis.

For the reason of economy, farmers and structural engineers prefer the vinyl house frame members that have the lightest cross sections. Therefore, in order to reach this aim, rod bracing system is the best method for multiple vinyl house frames. In this study, wire rods (tension members) are used to be bracing members in multiple vinyl house frames. The effects of additional wire rods in the frames are investigated by the variations of the bending moments, axial forces, displacements and combined stresses in the main frames that are reinforced by different shapes of rod bracing system. Vinyl house frames are usually made by steel pipe members and collapsed by the excessive wind and snow loads. Two kinds of bracing models are used for wind and snow loads separately in this study. The effective bracing models for each load are finally figured out.

In this study, the optimum structural components of the rural house using the light gage cold-formed steel frame is proposed. The model for selecting the optimum structural components, determines the range of load by the region and size of house, calculates the weight of the component by structural design process and optimizes a kind of the component by sensitivity analysis of the component to the total weight.
