본 연구의 목적은 방진층을 가진 바닥판을 포함한 건축물의 동적해석을 위하여 효율적인 모형화 방법과 이에 대한 해석법을 제안하는 것이다. 이를 위하여 방진층을 포함한 바닥판의 모형화를 위하여 바닥슬래브와 상부 마감층을 각각 독립적으로 모형화하고 이들 사이에 방진층을 의미하는 스프링 요소를 사용하였으며 방진층의 감쇠에 의한 비비례 문제를 해결하기 위하여 Newmark-{\beta}법을 적용하여 동적해석을 수행하였다. 상하부를 각각 모형화함으로서 방진층 상하부의 재료적 차이에 의한 감쇠거동을 정확하게 모형화할 수 있었다.

Computerized visual database construction of architectural precedents has just begun in some research institutes in the world. In Korea the first visual database has shown its testl version by S architectural design firm in september 1996. In this article the author discusses the historical contexts and the recent computerization cases, the traits, the uses and the limits of architectural visual database system of precedents. The forms and contents of data fields in two cases are compared with a focus on the description of architectural traits of each data entry. Compared to the KIA format, the S database has better performance for architectural design reference because it collects more pictures and drawings and larger texts for the field of architectural chracteristics. But this latter also is constrained by its capacity of memory and so lacks the reciprocity of the DOORS in the Graduate School of Design, Harvard University. A visual database system which has more flexible allocation of memory and respondent with the users is yet to be prepared. But this system also should be maintained by some experts in architectural history, theory and criticism, because their knowledge is essential for selection of precedents and revision of the data description. A full-fledged electronic visual database in architecture will not only save much effort for the architect, but also will change the architects' design behavior. Nevertheless this does not mean the automatic promotion of architects' creativity.
