Constructing Journal week 3Part 1:In this week’s tutorial, we visit four places in the campus and also observed their structure andmaterial. Following is some information about those architectures.ERC Building

Potential Construction Constrains_ERC was built between two old buildings

Links to other buildings_Steel Beams and Skylight ( glass)

Construction type_Steel Frame Construction

Structural System (s)_Column Structure

Materials_Glasses, batten, steel, blue stone, concrete, plywood

Other relevant comments_Using the glass to be a skylight which can save electricity in the day time and this is to obtainsustainability.MSLE Building (Link Between Buildings)

Potential Construction Constrains_

The highest place isapprox 9m and the lowestplace approx 6m

MSLE was built between two old buildings

Links to other buildings_Concrete Structure

Construction type_Stairs and wall: mass constructionRoof: frame construction

Structural System (s)_Cantilever Structure and beam structure

Materials_Concrete, glasses, scam, zinc, stainless, steel, brick.

Other relevant comments_The cantilever is the most special part in this building which is only depends on one side’s wall tooffer the whole force to the cantilever. I also noticed that the cantilever used steel nails to stickitself on the wall.

Using a 1.8m hight person asunit, it approx 3.5 peoplewhich is 6.3m

Queens College Extention

Potential Construction Constrains_An extention part where can expand the using area for this building.

Links to other buildings_It is still building now...

Construction type_Mass Construction

Structural System (s)_Simple Structural SystemColumn StructureMaterials_Timber, brick, concrete, granite, steel

Other relevant comments_This building’s original part using the steel truss to fixed roof which can be seen in the second pic.

Approx 6.5m - 7 m

Ormond Theology Centre Reception

Potential Construction Constrains_This should be the extention part for the left side building.

Links to other buildings_Copper sheet

Construction type_Steel frame construction

Structural System (s)_Less weight

Materials_Copper sheet, PVC down pile, Concrete(where include the timber inside), glass, steel, brick, stone.

Other relevant comments_The copper sheets make the steel pipeline not be easily broken.

Approx 6m--6.5m

Part 2:Task:

Our groups’ design:

Destroying Time:Group 1 :

Group 1 model is a triangle structure (Tension and Compression structure), which doesfirm and strong enough with the thick timber( 35×35), however the broken place is the thintimber (3×40 timber). And that thin timber deformed firstly then gradually broken. We canfind material’s flexibility is important to a building.

Group 2:Group 2 model seemsnot too firm and can bebroken easily, the model’slabored point is onlydepend on the thick timber(35×35cm), so thisstructure makes themodel only can obtain 7rounds’ force from verticalside.

Group 3 (Our Group)

Our group’s model is very strong which obtains 12 rounds force from vertical. The wrongplace in our designing is where we made “feet” under our span which made the verticalforce can’t be standard and balance and finally dead. During our constructing, we usedbench drill which help us decrease the time that we should spend and it does very helpful.On the other side, the method we setting the 3×40 timer is put it vertically, because whena force coming vertically, then the timber can bear a maximum force to against it, and thisis the success point!
