Abstract

Evaluation indices of the panelizing optimization for Architectural freeform surfaces are proposed for quantitative evaluation through the case studies on panelizing optimization and evaluation index for Architectural freeform surfaces. Proposed evaluation items are adherence to original design intent, production ease, and continuity. The evaluation index for adherence to original design intent is surfaces fitness, the evaluation indices for production ease are planarity, planar panel ratio, and the evaluation indices for continuity are tangent continuity, and divergence. Algorithms are also suggested to compute the proposed evaluation indices.

비정형 건축곡면의 패널분할 최적화 정도를 평가하기 위한 여러 가지 최적화 평가기법들이 개발되어 적용되고 있으나 이러한 평가기법과 평가지표들은 독립성, 보편성을 확보하고 있지 못하다. 그러므로 본 연구에서는 비정형곡면 패널분할 최적화 평가기법 및 평가지표에 관한 사례 및 선행연구 고찰을 통한 독립성 및 보편성이 확보되는 비정형 곡면 패널분할 최적화의 정량적 평가를 위한 평가항목 추출과 평가지표의 제안이 이루어진다. 제안된 세 가지 패널분할 최적화 평가항목은 원형 충실도, 생산 용이성, 연속성이며, 원형 충실도를 위한 평가지표로는 곡면 일치, 생산 용이성을 위한 평가지표로는 평면성, 평면 패널 비율, 연속성을 위한 평가지표로는 접선 연속성, 사이 간격이 제안되었으며 그 산출방법이 함께 제안되었다.
