  • This study lays emphasis on the development of efficient analytical models for a multistory structure with wings, including the in-plane deformation of floor slabs. For this purpose, a multistory structure with wings is regarded as the combination of multistory structures with rectangular plan and their junctions. In addition, a multistory structure with a rectangular plan is considered to be an assemblage of two-dimensional frames and floor slabs connecting two adjacent frames at each floor level. This modeling, concept can be easily applied to multistory structures with plans in the shape of L, T, Y, U, H, etc. To represent the in-plane deformation of floor slabs efficiently, a two-dimensional frame and the floor slab connecting two adjacent frames at each floor level are modeled as a stick model with two degrees of freedom per floor and a stiff beam with shear deformations, respectively. Three models are used to investigate the effect of in-plane deformation of the floor slab at the junction of wings on the seismic behavior of structures. Based on the comparison of dynamic analysis results obtained using the proposed models and three-dimensional finite element models, it could be concluded that the proposed models can be used as an efficient tool for an approximate analysis of a multistory structure with wings.

  • Fully rigid floor diaphragm is one of the main assumptions that are widely used in common practices due to its simple application. However, determining the exact degree of diaphragms flexibility cannot be easily accomplished without finite element modeling, which is an expensive and time-consuming procedure. Therefore, it is always possible that apparently rigid diaphragms, based on prescriptive limitations of seismic codes, experience some degrees of flexibility during the earthquakes. Since diaphragm flexibility has more uncertainties in asymmetric-plan structures, this study focuses on errors resulting from probable floor diaphragm flexibility of torsionally restrained structures. The analytical models used in this study were single-story buildings with asymmetric plan and RC shear walls. Although floor system is not considered explicitly, a wide range of considered diaphragm flexibility, from fully rigid to quite flexible, allows the results to be generalizable to a lot of lateral load resisting systems as well as floor systems. It has been shown that in addition to previously known effects of diaphragm flexibility, presence of orthogonal side elements during design procedure with rigid diaphragm assumption and rapid reduction in their absorbed forces can also be an important source to increase errors due to flexibility. Accordingly, from the obtained results the authors suggest designers to consider the possibility of diaphragm flexibility and its adverse effects, especially in torsionally restrained systems in their common designs.

  • In this research, an object-oriented Petri net model for representing a flexible process plan is proposed, which is hierarchically multi-faceted for supporting planning, scheduling, and shop floor control functions. The multi-faceted process plan model consists of the following: a) an object model which represents on object-oriented data model, b) a static model which represents a process flow model with process alternatives, and c) a dynamic model which represents a process activity model with resources alternatives, of a flexible process plan. Petri nets allow the static and the dynamic process plan models to be represented in a unified formalism with an ease of model transformation. The multi-faceted process plan model suggested in this paper, is illustrated with a prismatic port in comprehensive detail.

  • Purpose: Design inducement incentive item and formula on permitted floor area ratio in district detailed plan have been improved to reflect the actual application of guidelines and the social needs of city and architecture. However, the current guideline has a limit to realize the purpose of the plan. This study proposes improvement of the items and parameters in formula. Method: This study analyzed the district detailed planning guidelines since 2000 and the cases of general type district unit plan. In order to propose improved items and parameters, planing purposes and present parameters were compared and analyzed. Result: Items of guidelines have been changed according to public needs. High necessity items were applied to large parameters, and these items have been changed as the guideline changes. Diversity of items depended on regional characteristics, and parameters were more flexible than items for most cases. The purposes of plans, parameters and items were analyzed and it revealed four items needed improvement; the inducement of the limited building line, the improvement of the pedestrian and street environment, the necessity of the open space, and strengthening of the regional agreement. For improvement, this study added items and improved the relevance between items and sub-items. The parameters were improved by considering the importance, feasibility and comparing them with each other. Simulated result confirmed that proposed guideline is appropriate to operate, and also characteristics of area encourage to operate it more flexible.

  • A shop floor control system (SFCS) is the central part of a CIM system used to control the activities of several pieces of manufacturing equipment (e.g., NC machines, robots, conveyors, AGVs, AS/RS). The SFCS receives orders and related process plans, and then performs selecting a specific process routing, allocating resources, scheduling the workpieces, downloading the processing instructions (e.g., RS-274 instructions for NC machines, VAL II programs for robot), monitoring the progress of activities, detecting and recovering from errors, and preparing reports on the status of the manufacturing system. Simulation has been utilized in discovering control policies used for resolving shop floor be control problems such as resource contentions, part dispatching, deadlock. The simulation model must be designed to respond to real-time data coming from a shop floor. However, to rapidly build a realtime simulation model of SFCS cannot be easily accomplished. This talk is to address an automatic program generator of discrete event simulation model for shop floor control from process plans and resource models. The program generator is capable of constructing complete discrete simulation models for multi-product and multi-stage flexible manufacturing systems.

  • 모듈러주택은 세계대전 이후 신속하고 효율적인 주택공급을 위해 시도되었다. 국내에서도 30년 이상 품질 및 시공방법 개선을 위한 노력을 했으나 경쟁력있는 주택 상품이 되진 못했다. 모듈러 주택은 라멘구조로 평면구성을 자유롭게 할 수 있지만, 대부분 벽식 구조의 일반적인 아파트 평면을 분절한 형태로 변형하여 시공한다. 모듈러 주택의 생산 및 구조적 측면의 장점을 강화하기 위해서는 평면, 건축 구성재의 부품화 및 표준화, 자재, 제작 및 시공법, 공정관리, 공사비 관리 등 종합적인 측면에서 자동차와 같이 공장생산 시스템에 적합한 모델을 발전시키는 것이 필요하다. 본 연구에서는 생산 및 호환을 위해 MC(Modular Coordination)설계원칙을 적용하여 운반 및 생산 용이한 3m×3m 모듈을 공간의 기본 단위로 설정했다. 빌트인 가구를 포함한 3m×3m공간을 다양한 형태의 제품과 같이 생산하고, 이를 거주자의 기호에 맞게 조합하여 46m2 평면을 완성하는 방법을 제시했다. 생산설비, 운송수단, 시공크레인에 따라 생산 모듈을 다르게 설정할 수 있으며 운반장비가 소형화될수록 생산모듈의 가짓수도 적어질 수 있다. 이와같은 모듈러 주택 생산방식은 거주자의 요구에 맞춰 다양한 평면의 주택을 제공하기에 용이하고, 기술과 시스템의 발전에 따라 시공속도도 가속화할 수 있을 것이다.
