Project: Passenger Clearance Building, RSHP + Aedas
Through the steps shown in the previous images, the part of the problem that is being sorted out is the continuation and improvement of the base module of the corrugated roof shape.
The algorithm was carried out based on the indications given in class, but some modifications were carried out in order to bring the shape of the model closer to the real project.
As seen in the technical drawings of the project in question, along the longitudinal axis the structural grid has a spacing, which varies alternately, of 35 and 30 meters. In this way, the pillars are arranged in pairs that have a distance of 35 meters between each pillar and that are 30 meters apart from the next pair of pillars. As a result, each covering module has a length of 65 meters longitudinally.
Regarding the transversal axis, it can be seen that the structural grid has a fixed distance of 42 meters between the 5 axes. Between each axis, 2 covering modules are inserted, with a horizontal displacement of half a module. Consequently, each covering module has a length of 21 meters transversally.
Furthermore, other design features that were taken into account were the height (z axis) of the roof module. Longitudinally, the module raises about 10 meters (between the base and the top of the curve). Longitudinally, the module also has an arch that rises by about 1 meter.
Taking into account the characteristics described above, the following modifications were carried out in the base algorithm for the covering module: (1) the distance between the initial and final points of the module was set as 65 meters (equal to the longitudinal length of the module); (2) the end of the target domain for the remap component was set out as 10 meters (equals to the maximum longitudinal rise of the cover module); (3) the offset curve distance was set to 21 meters (equal to the transversal length of the roof module); (4) the midpoint of the connecting line of the two curves was moved by a vertical vector (unit z) of 1 meter (equal to the transversal elevation of the covering module); (5) the perpendicular planes, which served as the basis for the rectangle component, were realigned with reference to the first one (this step was necessary because it was found that some rectangles along the curve had their distances on the x and y axes inverted).
The next steps to be developed for modeling the project can be: (1) model the side beams that define the modules; (2) define which other coverage layers will be represented, and model them; (3) replicate the covering module, in order to obtain the coverage in its entirety; (4) model the pillar; (5) replicate the pillar module according to the structural grid; (6) think about the connections between the pillar and the roof; (7) consider how far to model glazed closing surfaces and internal seals and slabs.
