Explanation

해석선 생성

시작점과 끝점에서 다른 단면을 갖는 해석선을 생성합니다.

Image Removed

  • [Select Member]

    • Property Reference : Material과 Structure 정보를 참조해올 Member 객체를 선택합니다. 하나의 Member만 선택 가능합니다.

    • Sectioning Reference : 단면 취득 시 사용할 Member 객체를 선택합니다. 여러 개의 Member를 선택할 수 있습니다.

Info

Analysis Line의 경우 Analysis Mode에 진입하는 시점에 Reference로 부터 속성 정보를 참조하고 단면을 취득합니다. 즉, Property Reference나 Sectioning Reference로 선택한 Member를 해석선 생성 후 속성 변경, 삭제, 혹은 이동을 할 경우 해석선 생성 시점의 정보가 아닌, 해석 모드 진입 시점의 정보를 활용하여 해석용 모델을 생성합니다.

  • [Draw / Select Edge]

    • By Draw : Analysis Line 생성 방식을 선택합니다. 선을 작도하여, 해당 선의 형상으로 Analysis Line이 생성되게 합니다.

    • By Select : Analysis Line 생성 방식을 선택합니다. Edge를 선택하여, 해당 Edge와 겹치게 Analysis Line이 생성되게 합니다.

  • [Analysis Line Table]

    • Name 열 : 해당 행의 Analysis Line에 부여될 이름이 출력됩니다.

    • Reverse Direction 체크박스 열 : On으로 설정할 경우 선택하여 생성한 해석선의 시작점과 끝점의 위치가 바뀝니다.

    • Tapered Section 체크박스 열 : On으로 설정한 경우 시작점에 배치할 단면과 끝점에 배치할 단면을 다르게 설정하여 변단면 해석용 모델을 생성합니다.

    • Sectioning Offset (S) 열 : 해석선의 끝점에 배치할 단면을 취득할 지점을 설정합니다.

    • Sectioning Offset (E) 열 : 해석선의 시작점에 배치할 단면을 취득할 지점을 설정합니다.

  • 아래와 같은 부재를 대상으로 Analysis Line을 생성한 경우,

Image Removed

  • Tapered Section 체크박스를 Off으로 설정한 경우 Analysis Line의 Start Plane 단면 취득점에서 취득한 단면을 해석선의 시작점에 배치하고, End Plane 단면 취득점에서 취득한 단면을 해석선의 끝점에 배치하여 해석용 모델을 생성합니다. 그리하여 아래와 같은 해석 모델이 생성됩니다.

Image Removed

  • Tapered Section 체크박스를 Off로 설정한 경우 Analysis Line의 Start Plane 단면 취득점에서 취득한 단면을 해석선 전체에 배치하여 해석용 모델을 생성합니다. 예시 모델의 경우 아래에서 윗방향으로 생성된 Analysis Line이므로 아랫 단면이 시작면입니다. 그리하여 아랫면에서 취득한 단면이 해석선 전체에 배치된 것입니다. Reverse Direction 옵션을 On으로 설정할 경우 윗단면이 해석선 전체에 배치되어 해석 모델이 생성될 것입니다.

title상세 설명 (Sectioning Offset)

  • 해석선의 시작점에서 Sectioning Offset (S)에 입력한 길이만큼 해석선의 끝점 방향으로 떨어진 지점을 시작면 취득점으로 지정합니다. 또한, 해석선의 끝점에서 Sectioning Offset (E)에 입력한 길이만큼 해석선의 시작점 방향으로 떨어진 지점을 끝면 취득점으로 지정합니다.

  • 각 취득점에서 해석선에 수직인 평면을 그리고 해당 평면과 Sectioning Ref 객체들과의 교차면을 각각 해석선의 시작점과 끝점에 배치하여 해석용 부재를 생성합니다.

  • Tapered Section 체크박스를 Off로 설정한 경우 Sectioning Offset (S) 입력란만 활성화되며, 해당 지점에서 취득한 교차면을 해석선 전체에 배치하여 해석용 부재를 생성합니다.

  • 아래와 같은 부재를 대상으로 Analysis Line을 생성하고 Sectioning Offset (S) 입력란에 2m, Sectioning Offset (E) 입력란에 1m를 입력한 경우,

Image Removed

  • 우선적으로 아래 그림과 같이 입력한 Offset 길이만큼 떨어진 지점에서 Sectioning Ref 객체를 자른 교차면을 취득합니다.

Image Removed

  • 그 후, 취득한 단면을 해석선의 시작점 및 끝점에 배치하여 아래의 하늘색 같은 형상을 만들고 해석용 부재로 활용합니다.

titleDetailed Explanation (Tapered Section)

If you created an analysis line for a member as shown below.
you created an edge in advance to create a 1D analysis line in a straight direction, but there was a discontinuity in the cross section (a mismatch in the number of vertices), so you separated the edge at that location.
