Week 1 eLearning
Constructing Environment Overview
Introduction to Materials
Loads on buildings
Kinds of Labor
Basic Structural forces
Eg. Wind pressure/earthquake
Load Path Diagrams
Common used as foundation in Melbourne CBD
For the week 1 eLearning, it introduces the concept of constructing environment. It briefly mentioned the constructing materials and the Melbourne’s bluestone structure, and talks about the dead loads and live loads in the video. In the Ching, Chapter 2.08 to 2.11 are the explanation of Loads on buildings.
Week 1 Tutorial
The tutor talks about the bending when the load puts on a piece of material. No matter the material is made of timber, ion or other materials, the bending will still occur.
The diagram is shown how the dead load transfer through the bridges into the ground. It can argues that the load will transfer to the end of each bridge. And donâ€™t forget the ground will provide the forces to support the bridges.
The activity of the first tutorial is bulding a tower as high as possible and allow a animal toy to fit in.
I find out the common structure of the tower in our class. The first structure of the tower is more stable than the second one, especially when the tower gets higher. But the second structure can reach to the higher height when using the same amount of the piece of materials. The first structure gain more support from the ground, because it has the greater surface area that is touch the ground. Also the second layer is gain more support from the first layer.
Environmentally Sustainable Design (ESD)
Week 2 eLearning Building Systems
stages of a material’s life.
The disposal of waste products back to the earth or recycled into other products.
Structural system Support and transmit applied gravity and lateral load

The shell or envelope of a building, consisting of the
roof, exterior walls, windows, and doors.
Common ESD Strategies:
Provide essential services to a building. Eg. Water
supply system, sewage disposal system, heating/
ventilating/ air-conditioning systems
Nigh air purging Solar energy
Roller Joints (only vertical load)
Wind energy Cross ventilation Smart sun design Insulation Water harvesting
Week 2 Tutorial Activity Building a stable tower to reach the ceiling We in groups of five and build a tower by using balsa. We connected different pieces of short and small balsa together to make a long piece. However, the connections are not well enough to keep the frame straight, so it leads to the unbalance structure, which is decrease the stability of the tower. We used a triangle based in order to reduce the flexibility of the tower, and connected the edges by another piece of balsa to increase the stability.
