As Part of a brief I received for my 2nd year studying Architectural technology, we where asked to produce a 1:20 scaled section through an as-built framed structure in Greenpoint park. 

 Above is a section through an open air amphitheatre in Green Point park.

It is constructed with gumpoles,concrete,steel and timber.

`  

A Framework is constructed using verticle gum-poles and steel I-beams.This Framework is normally called the primary structure as it is the beginning process of construction , similar to a skeleton in the human body.   This framework is normally load bearing as it supports other materials used in the structure. On the Right is an example of  the framework and how it supports the roof .

Cladding and other nessesary elements are added to the framework to make it funtional. this is refered to as the secondary structure.

for example secondary structure would be a brick infill wall in a framed concrete structure or in the case of  the structure in Green point a secondary structure would be the stone walls or the suspended timber floor. Cladding such as sheeting or aesthetic materials added to the framework is also considered a secondary structure. 

In some cases where a post and lintel style of construction is used , it is necessary for lateral bracing to be used to act against horizontal forces such as wind. This reinforces the structure and distributes the horizontal forces to the footing of the structure. On the right is an example of the bracing used in the Green Point structure. the use of tensile steel cabling keeps the gum poles in tension , transferring loads to the footings of the gum poles

Each individual member has its on function, but for the structure to act as a unit each member needs to be fixed to another member and so forth. fixings are important as they transfer weight through the join of the members. In some cases fixings need to be engineered to the tee to assure the safety of the inhabitants or users of the structure. on the right and below are example of the fixings used in Green point.
steel is useds as it has a higher shear strength than concrete or wood but still has some flexibility. Fixings on the ground need to have a high compressive strength to transfer all the load-bearing weight above it to the concrete footing. Fixings from member to member do not necessarily have to be as strong and a ground fixing as it is combining the properties and strength of 2 or more members, witch in turn creates a stronger bond.

 Different materials have different properties as we all know. it terms of horizontal and vertical spaning, steel has the highest and is predominately used to span over large areas without the support of a central support beam. in some cases cabling is used to reinforce the steel which in turn strengthens the beam. On the right is an example of how far a steel beam can span. In the case of the Green Point structure the beam does not have excessively heavy materials above it thus it can span a longer distance.
Different shape Steel beams are used in different situations, in this example the 'I' beam was used.
