冰棍棒桥设计与建造

STRUCTURE  BRIDGE

To design a Bridge structural as stable to assemble and constructed to function as a whole to support and transmit loads and forces to the ground.Aim: The design process is to explore the principle of greatest structural capacity for least structural weight. This is called a ‘strength-to-weight ratio’, where ‘strength’ is the load/weight that the bridge can carry, and ‘weight’ measures the weight of the bridge itself. The higher this number, the greater the bridge’s efficiency or the better its ‘strength-to weight’ ratio.Purpose: Construct a bridge made from ice block sticks, string or cotton, glue and/or pins. Rules: Your bridge will weigh a maximum of 300grams.

DESIGN  PROCESS

BRIDGE MODEL  1

The triangle signifies stability When resting on one side, the triangle is an extremely stable figure. The challenge towards it was the originality of its structure. The logic behind it was taken in Francis Ching’s book pg. 40. Trying to avoid the design of a standard truss look found to be more difficult in the beginning stages as my idea was set to bridges that we see today and pictures from books. “Whatever good things we build end up building us. “Jim Rohn.

Bridge 1: Weight 296 grams, Strength 5,000, Ratio 16.89

DESIGN PROCESS 2

Bridging the gap between performance and development. The bridge should be made longer than the rig span. When placed under stress from loading the structure often bends decreasing in length, which can result in the bridge falling off the rig.

Structure  Bracing

These Structural Systems are generated by rope holding the structure together. which generate different bridge bracing through beam, cantilever, arch, suspension, cable-stayed on bridge 2.Bridge 1: Weight 296, Strength 5,000 grams, Ratio 16.89

Bridge 2 was determined by its stability by having Arch roll against eachother causing tension to vibrate through to the bottom brace. Changing the topcord in bridge 1, into an arch created attention. The originality and engineeringthat looks cool and stayed strong.
