Structural Joint

Span The extent or measure of space between two points or extremities, as of a bridge or roof; the breadth.

A joining of two pieces of material in wood, metal or plastics by mechanical means.

Frame To build by putting together the structural parts of; construct.

Bracing

A support.

STUDIO REPORT Top View:

Bottom View: Aim: • To build a stable structure long enough to bridge across a 1500mm gap. • Using limited amount of material (600mm x 100mm x 2mm piece of balsa)

This bridge is wide and it has the shape of triangular prism. It was constructed by thin beams. The way to connect each beam was using glue tapes and pins. However, the structural joints of the model were still very weak, which were broken many times during the process.

Side View:

STUDIO REPORT Other group’s work This bridge is narrow and it has the shape of quadrangular prism.

It was constructed by thick beams.

The top view of the bridge:

The bottom view of the bridge:

The side view of the bridge: The way to connect each beam was using pins only. Because the beams of this bridge were thicker than the beams of ours bridge, the structural joints of this model were stronger, which means they would not be broken easily.

Because of the limited amount material provided, as they made thicker beams, the number of beams of this bridge was less than the number of beams constructed of our bridge. In other words, this bridge looks simpler.

STUDIO REPORT Comparison between two groups’ work The bridge is weak but stable.

When put a rule on it, the bridge will sink slowly and be broken by the weight of the ruler.

Therefore, this bridge is suit to place the things in lighter weight, which will give less loads to the bridge.

The bridge is stronger but less stable.

When put a rule on it, the bridge will lean on one side, which is hard to keep the balance of the bridge.

Therefore, this bridge is suit to place the things with smaller size, which is easy to make the bridge be balanced.

LEARNING LOOP The Aims of Building systems are Performance requirement (including structural compatibility, integration and safety) Aesthetic qualities Regulatory constraints Economic considerations Environmental impact Construction practices.

•

According to Ching 2.02, Structural System was designed and constructed for supporting and transmit the gravity and lateral loads safely to the ground without exceeding the allowable stresses in its members.

•

Enclosure System---the system is the shell or the envelope of the building, such as roof, exterior walls, windows and doors.

It includes the items of the building which do not belong to the Structural System.

The Enclosure System provide the physical access to the different area of the building and it is also itself which divided the interior space of the building.

Mechanical system is the system which provide the essential functions of the building including water supply, heating, electricity ,transport(such as lifts) and the recycle system.

ESD—Environment Sustainable Design e.g. thermal mass, solar energy, water harvesting, night air purging The facade of a building is typically considered part of the enclosure system.

All of vertical, horizontal and rotation movements will a fixed joint restrict.
