효율적인 유지관리및 에너지 수율의 이유로 인해 직사각형의 형상을 가지는 기성품 photovoltaic panel들을 사용하게 됩니다. Dubai의 모래먼지가 많은<br />

환경에서 pv panel 들의 청소및 유지관리는 또다른 중요한 고려 요소가 되며, 이를 위해 각 pv panel들은 panel 의 양끝단에 위치한 maintenance gutter 위에<br />

앉혀집니다. 아래의 process는 초기의 gutter로부터 pv panel의 길이를 고려한 특정한 거리상에 다음번의 gutter의 위치를 정하기 위한 geometric rule을<br />

설명하고 있습니다.<br />

STEP 08_CATWALK GEOMETRY SET OUT<br />

Catwalk Assemblies<br />

Clearance Surface for Catwalk<br />

Top Chord Surface<br />

Bottom Chord Surface<br />

Circle line to start Catwalk Assemblies<br />

Goals<br />

A: Keep the distance for the ‘PV Cassettes’ consistently between ‘Catwalk Assemblies’<br />

B: Maintain a constant clearance from the ‘Canopy truss structural top surface’ to the ‘PV Ring beams’<br />

C: Keep a single ‘Catwalk / Gutter’ cross section and orientation at all locations<br />

Process<br />

1) Offset upper chord surface by required clearance<br />

3) Create circle with a radius equal to the target span for the PV Cassettes centered on the center of the ring beam or lowest required<br />

point for clearance<br />

4) Move the circle over on the axis of the gutter's walkable surface by the length of the catwalk opening in the direction of the next<br />

segment. This will account for the plank being "layed" from the right hand side of the lower gutter assembly vto the left hand side of<br />

the next gutter assembly above<br />

5) Intersect this circle with the offset curve to get next placement point<br />

6) Translate the cross section from the center point of the ring beam to the new intersection point.<br />
