Architectural fabrics are now used in membrane structure with the merits of free shape, lightness and opened up new possibility for the design of new building structures. Recently PVC, PVF, PVDF, PTFE coated fabric for using the membrane structures. However, clear standards for the design and construction is not exist because of the lack of Architectural fabric research. In this paper, Flammable properties of PVDF, PTFE coated fabrics are obtained through the Flammability test using the Cone Calorimeter. Based on these results, identify the fire resistance property of the Architectural fabric.

This study examines the significance of digital fabrication of scaled physical models in the digital design process and highlights the integration of design computing and digital fabrication in architectural education. Advances in CAD/CAM technologies have increasingly influenced building design and construction practices by allowing the production of complex forms that were once difficult to design and construct using traditional technologies. At the advent of digital architecture, schools of architecture introduced digital technologies to their curriculum, focusing more on design computing than digital fabrication, preventing students from completely mastering digital technologies. The significance of digital fabrication for scaled physical models as a design media within the digital design loop is discussed. Two case studies of leading schools of architecture that are successful in building the bridge between both areas are given. These focus on the curricular structure to integrate both areas within design studios. Finally, a curricular structure offering students a balanced approach to these areas of knowledge is proposed based on what was learned from these case studies.

Public institutions and owners have been introduced to use Building Information Modeling (BIM) tools. Learning BIM becomes an important factor in design process of undergrad program. The purpose of this study is to demonstrate an integrated architectural engineering design process using BIM tools. BIM education programs are analyzed to compare the level of detail in BIM education. An architectural engineering design class needs to involve BIM to introduce integrated process. An architectural engineering design process needs be based on understanding design, building structure, construction and building services. 3D Modeling helps understanding a building structure and checking environment-friendly element analysis. As a result of this research, new process of design education is proposed under four issues.

The tombs at the royal level of the Western Han dynasties belong to the five kingdoms of Chu, Liang, Lu, Zhongshan and Changyi, representing the new forms and ideas of the tomb architecture. Taking Shanchuwang Tomb in BeidongShan, Xuzhou as an example, this paper analyzes the architectural structure and symbolic significance of the tomb, and tries to discuss the concept of burial reflected in it.The analysis of the structure of the main body of the tomb reveals the basic logic of the tomb imitating the palace on the ground, and the definition of the nature of the annex reflects its transcendence over the general form of the tomb.

This study investigates how the spatial recognition structure is emerging through the case of rectangular plan combined with a combination of Dang-Sil(堂室) and Gong(工) shape roof, and identifies a type of architecture in the early Joseon Dynasty that has never been revealed. The conclusion of this study is as follows. First, the Dang and the Sil are connected to each other, but the architectural elements such as pillars, frame, and windows are distinguished and appear as separate buildings. Second, the distinction between Dang and Sil is evident by the difference in the number of ridges and the shape of the roof. In addition, the roof and roof framework of the independent rooms and the rooms were common in the right angled architecture where the direction and the expandability of each structure were maintained. Third, the construction of the Dang-Sil combined structure, in which two or more structure frameworks were combined with the rectangular combined flat roof structure, gradually changed into a single structure with a single ridge. Fourth, this change means that people of the early Joseon Dynasty recognized the Dang and Sil as separate architecture, but the strict sense of spatial separation has disappeared over time.

In this study, the performances of a passive tuned mass damper (TMD) and a semi-active TMD (STMD) were evaluated in terms of seismic response control of elastic and inelastic structures under seismic loads. First, elastic displacement spectra were obtained for damped structures with a passive TMD and with a STMD proposed in this study. The displacement spectra confirmed that the STMD provided much better control performance than passive TMD and the STMD had less stroke requirement. Also, the robustness of the TMD was evaluated by off-tuning the frequency of the TMD to that of the structure. Finally, numerical analyses were conducted for an inelastic structure of hysteresis described by the Bouc-Wen model. The results indicated that the performance of the passive TMD whose design parameters were optimized for an elastic structure considerably deteriorated when the hysteretic portion of the structural responses increased, and that the STMD showed about 15-40% more response reduction than the TMD.

In the early of Joseon Dynasty, Royal Tomb developed from stone chamber tomb to lime chamber tomb through precedents. The lime chamber tomb consists of main-chamber(JeongGwang) and sub-chamber(ToeGwang). This separation makes character to construct tumulus of the Royal Tomb half and half. By this character, the Royal Tomb are not constructed by separate structure but constructed by coadjustment. The underground structure and tumulus of the Royal Tomb affect each other in the size and method of construction. The selecting type of Royal Tomb is generally made decision through terrain and politics. This study prove the architectural structure is also one of the major cause the that select type of Royal Tomb.

Isogeometric concept is introduced to find out the optimum layout of plane structure under free vibration. Eigenvalue problem is formulated and numerically solved in order to obtain natural frequencies and mode shapes of plane structures. For the exact geometric expression of the structure, the Non-Uniform Rational B-spline Surface (NURBS) basis functions is employed and it is also used to define the material density functions. A node-wise design variables is adopted to deal with the updating of material density in topology optimization (TO). The definition of modal strain energy is employed to achieve the maximization of fundamental frequency through its minimization. The verification of the proposed TO technique is performed by a series of benchmark test for plane structures.

Damage location and extent of structure could be detected by the inverse analysis on dynamic response properties such as frequencies and mode shapes. In practice the measured difference of natural frequencies represent the stiffness change reliably, however the measured mode shape is insensitive for stiffness change, but provides spatial information of damage. The damage detection index on shear building structures is formulated in this study. The damage detection index could be estimated from mode shape and srory stiffness of undamaged structure and frequency difference between undamaged and damaged structure. For the verification of the observed damage detection method, the numerical analysis of Matlab and MIDAS and shacking table test were performed. In results, the damage index of damaged story was estimated so higher than undamaged stories that indicates the damaged story apparently.
