Group activities For the first week's group activities, we plan to use the




establish a tower which provides with a entrance for the toy dog and a roof that can cover the tower.

After our group discussion, we consider that the most simple way for arranging the bricks is probably the most stable way.

While we are building, we think about two related things which is necessary: A entrance that allow the toy dog to move in and out loosely. A small Arc that higher the height of the toy dog

Two bricks' distance

As we are making it higher, we find some trouble at the corner that we can only leave the problem at there.

We still use rubber band to make the roof which can cover the top of the tower.

Our tutor put some heavy things on the top of our tower in order to test the stability and we achieve a pretty good result!

The reason why we can succeed is that there is no space between each two bricks and the compression and tension on the brick act equally which is also an important factor.

Comparison with other class

These two towers show me some new ideas of making towers, they make the roof without the rubber band instead of angle tricks for building them. They may not as stable as we are, but in aesthetic view, they have a amazing structural and out looking. This is the information I should acquire from them.

Week 2 Log Book Knowledge map for elearning:

studio session activities reports Preparation for 'balsa tower'

sharp knife tape & glue pieces of basla First step: make a draft

With the reference with Performance & Requirements, we plan to make it high and stable. Consider about Aesthetic Qualities, our group plan to make multiple-triangles to make it simple and nice.

This impression drawing I find on the Internet which is close to our plan and draft.

For pratical making part: When we are making the foundation for the tower, we use kind of cross bracing to keep the frame more stable.

More importantly, we add a knee brace frame in the foundation to keep it like a simple K-brace form so that can bear the force act itself more safely.

As we are finish the tower, we find that some of our connection elements are not that stable as we expected. So we add some fixed joints to make the connectors and members more stable and of course more aesthetic.

Comparison with others' group

Our classmates use the simplest triangle way to establish their tower for their group. From my view, indeed it is stable but it must have all the members. If only one of them is cut, the load path will be also block and the force cannot exert on the object itself, therefore it falls down.

In order to test the stability of the tower, we cut some members of the system.

It fells down until we cut some balsa in the bottom, which shows the safety of the tower we made.

The reason of why our tower is more stable than 'the triangles one' is that the load paths are still the same act on the object and the dead load maintain the same as well.

Group Activity: Scale, Annotation and Working Drawing Conventions

Extra Questions • Q:How does the scale of the building compare to the scale of the drawings? How do the architectural and structural drawing differ? •A: Different part of building may use different scale for drawing. We always use a bigger scale for more detailed drawings and a small scale for a plan or elevation(like 1:100@A1). •Architectural drawing is used for design and it is used to understand the concept of design and space. However, structural drawing is more useful for the people who builds the architecture.

This week we have a off campus site visit in order to develop an ability to understand an unfamiliar building site and the different system used in construction projects of various scales

Foundation system(basement): Ground Anchors •To use this way in order to reinforce the foundation which at the retaining wall which loads will distribute into mud. Ground Anchors is a time saving solution for sites nowadays.

Some strategies being use •Post tension Pre-tensioned concrete is cast around steel cables or bars, while they are under tension. The concrete bonds to the tendons as it cures, and when the tension is released it is transferred to the concrete as compression by friction. Image retrieved from:

•The sill is not finished. The gap is risky because that it might not prevent corrosion and heat which may damage the material

•The caulk junction is used as waterproofing that prevent corrosion of moisture

Subject Glossary Load paths

Beam & Column Beams are rigid structural members designed to carry and transfer transverse loads across space to supporting elements. Column are rigid, relatively slender structural members designed primarily to support axial compressive loads applied to the ends of the members.

TENSION FORCES When an external load pulls on a structural member, the particles composing the material move apart and undergo tension. Tension forces stretch and elongate the material. The amount of elongation depends on the stiffness of the material, cross sectional area, and the magnitude of the load.

COMPRESSION FORCES A compression force produces the opposite effect of a tension force. When an external load pushes on a structural member, the particles of the material compact together. Compression forces result in the shortening of the material.

Week 3 Subject glossary • Moment –

The moment of a force is the tendency to make an object or a point rotate. •

• Slab on the ground

  A force will only produce a moment about a point if it is applied at a distance from that point along a line of action that does not pass through the point. •   Moments are measured by the product of the force magnitude and the perpendicular distance between the line of the action of the force and the point (this distance is called the moment arm). • Moments also have magnitude and sense. Since moments are the product of force and distance, the units are expressed in Newton-meter (Nm) or Kilonewton-meter (kNm).    Mo = F x d (i.e. moment = force x distance)

Concrete slabs-on-grade supported directly by the earth and thickened to carry wall and column loads form an economical foundation and floor system for one- and two-story structures in climates where little or no ground frost occurs

• Pad Footings: Also called isolated footings, these type of footing help to spread a point over a wider area of ground

• Retaining walls:

are used when sites are excavated to create basement or where changes in site levels need to be stabilized. The pressure load of the earth behind the wall need to be considered to prevent the wall from over turning

• Strip Footings: used when loads from a wall or a series of columns is spread in a linear manner

Week4 Subject Glossary Span • •

is the distance measured • between two structural supports. can be measured between vertical supports (for a horizontal member) or between horizontal supports (for a vertical member). is not necessarily the same as the length of a member.

Spacing • •

Span & Spacing

is the repeating distance between a series of like or similar elements. is often associated with supporting elements (such as beams, columns etc.) and can be measured horizontally or vertically. is generally measured centre-line to centre-line.

SPACING of the supporting elements depends on the SPANNING capabilities of the supported elements

Girders • Structural girders are used to construct a part of skeleton frame for structures ranging in size from one-story buildings to skyscrapers. Joists • There are many different kinds of joist: Steel joists, wood joists, etc. (This is a example of wood joists framing

•Soft storey It is relatively flexible in the ground storey, i.e., the relative horizontal displacement it undergoes in the ground storey is much larger than what each of the storey above it does. This flexible ground storey is also called soft storey.

Nail –

Reinforcement for connection

Screws –

May make a weakness point

Destructive Test Our designing structure collapses at the point when the load applied on it, it just reach about 430KG. It should be wider so that can reduce the bending stress

The crack is at where we use the drill to screw the plywood and pine, it makes a weakness point.

Comparison with other group

•This group uses the triangle to reinforce its structure which is a good way but the triangle itself is more stable than the structural itself which will reduce the stiffness
