Structures project 3

ALI NOLL AND BEN MANARSKI

DESIGN INTENT

LOCATED AT THE CORNER OF HENRY AVE. AND UNIVERSITY DR. THE INTENT OF THIS PROJECT WAS TO CREATE A SAFE AND COMFORTABLE BUS SHELTER USING A CLEAN AND STRAIGHTFORWARD STRUCTURAL SCHEME FOR THE UNIVERSITY COMMUNITY. THE USE OF STRUCTURAL ELEMENTS WAS DIRECTLY CORRELATED WITH ENVIRONMENTAL INFLUENCES SUCH AS SOUND, WIND AND LIGHT. COLUMN ELEMENTS WERE REPEATED MORE FREQUENTLY WHERE THESE INFLUENCES NEEDED TO BE MITIGATED. IN ORDER TO KEEP THIS PATTERN APPARENT COLUMNS PUNCTURE THE ROOF STRUCTURE AND KEEP A UNIFORM HEIGHT.

PLAN

NORTH ELEVATION

1/2” = 1’-0” 6

BUTTERFLY ROOF PITCHED SLIGHTLY TO THE SOUTH TO ALLOW FOR PROPER DRAINAGE. FINISHES OF ROOF ARE SUPPORTED BY 2X12 BEAM/ GIRDER SYSTEM.

VARIED COLUMN SPACING BLOCKS NOISE, WIND, LIGHT, AND OTHER ENCIRONMENTAL FACTORS AND ALSO PROVIDES SOME STRUCTURAL REDUNDANCY.

SEATING UTILIZES COLUMN STRUCTURE WHICH ALSO ALLOWS FOR ADDITIONAL PRIVACY.
