Public institutions and owners have been introduced to Building Information Modeling (BIM) tools. BIM has become an important factor in the design process in undergrad programs. The purpose of this study is to demonstrate the improvement of the architectural engineering design process through an analysis of BIM courses. BIM education courses are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM in the introduction of an integrated design process. An architectural engineering design process needs to be based on understanding design, building structures, construction and building services. 3D Modeling helps support an understanding of building structure and eco-friendly element analysis. The new process of architectural engineering design education is proposed as a result of this research.

Nowadays the widely used media in architecture include visualizations, animations and three-dimensional models. 3D digital methods using active CAM(Computer Aided Manufacturing) and CNC(Computerized Numerical Control) imaging have been developed for accurate shape and 3D measurements in freeform buildings. In contrast to a conventional building using auto CAD system and others, the proposed digital optimization method is based on a combination of 3D numerical data and parametric 3D model for design and construction. The objective of this paper is therefore to present digital optimization process for constructability of freeform building. The method can be useful in the effective implementation of an error-proofing process of freeform building during design and construction phase. 3D digital coordinate data can be used effectively to identify correct size of structural and finish members and installation location of each members in construction field. In addition, architects, engineers and contractors can evaluate design, materials, constructability and identify error-proofing opportunities. Other project participants can also include representatives from all levels of management, departments as well as workers and key subcontractors' personnel, if necessary. The 3D digital optimization process is therefore appropriate to serious variations in freeform shape. For future study, the developed digital optimization method is necessary to be carried out to verify the robustness and accuracy for constructability in construction field.

Recently, the fire risk of architectural structures is increasing due to the super high - rise and super - size of the buildings. Therefore, the direction of fire safety design tends to change from the existing design to the performance - based design. In particular, domestic fire safety policies are divided into building law and fire fighting law. In case of fire fighting law, performance design is already carried out. Therefore, this study summarizes the prediction formula for fire characteristics among the structural fireproofing design field as shown in Fig. 1 according to this situation, and compares it with the standard method of each country in particular.

고층화의 최대 장점은 과밀한 수평 밀집 환경을 건축물의 수직적 확장으로 과밀 현상에서 다층 보행자 시스템으로 대지의 공지를 활용하는데 있다. 이러한 초고층 건물은 특성상 건물의 강도, 강성, 안전성 등을 고려하여 설계가 이루어졌고, 이러한 특성으로 인해 비교적 건물 내의 대공간 확보와 평면의 자유를 얻기 힘들었다. 그래서, 이런 단점을 보완하기 위해서 그 대안으로 SAC조와 현수교 구조(Cable)를 제안하고자 한다.

In the case of structural analysis for building structures, the super-structure and the sub-structure are analyzed by using separate structural models in the field because of time saving, facile result interpretation and easy analysis of dynamic behavior. However this separate structural model violated the compatibility condition of structural analysis and it can not consider the interaction of superand sub- structures. In the present study, the analysis results of this separate model were compared to those of the unified model of super- and sub- structures which can consider the interaction of super- and sub- structures and reflect the realistic boundary conditions. According to the comparison results, the the analysis model using separate models can underestimate the member force and deflection of structural members in the super-structures and overestimate the deflection and member force of sub-structures. Therefore, in the case of high-rise buildings, irregular shaped buildings, buildings which are expected to be affected by large differential settlement and remodeling buildings, the unified structural model for super- and sub- structures was recommended for structural analysis instead of the separate structural model.
