Column and Beam Mass Construction Fabric Tensile

Building Systems:   

Enclosure System Structural System Mechanical System

Considering these systems we should take into account; performance requirements, aesthetic qualities, economic efficiencies and environmental impacts . Load Paths: 

Basic Structural Forces: A Force is any influence that produces a change in the shape of movement of a body. Types of Forces: 

Compression: external load pushes on a structural member, particles compact Tension: external load pulls on structural member, material moves apart

Source: Ching, Building Construction Illustrated, 2008, Chapter 2.11 Structural Forces

Static loads: applied slowly to structure until peak, doesn't fluctuate. Dynamic: applied suddenly, can have rapid changes in magnitude and position

Activity 3 Task Description: Week 1's tutorial task consisted of the students splitting up into groups of four with the aim of building a structure as high as possible made of out small rectangular wood pieces. Though the difficulty lay in the fact that the structure had to have a roof and a space in which a toy dinosaur could fit in. The task focused on the ideas of compression, tension, and force as previously discussed in the studio

Initial phase of construction consisted of a sound horizontal stacking in a semi circle structure. Due to its solid foundation the group was able to eventually enclose the semi circlet to form a roof but still able continue the horizontal stacking process. In order to gain maximum height we were able to develop a four by four layer method which we found to be extremely effective as it was easy and quick to initiate and due to our solid base was able to hold itself up quite easily. The diagram below demonstrates the structure found on the top half of the image in the bottom left of this page. In finishing our group was very successful as we achieved not only the tallest structure in our tutorial but also the tallest amongst all three tutorials. Upon reflection, the reason for our success derived from the simple and effective method incorporated into our process, as it was easy to build but also very secure


Week 2: Structural Systems:     

Skeletal eg eiffle tower Solid eg greek ruins Surface eg opera house Membrane eg wind sail Hybrid- cross between two

ESD, Environmentally Sustainable design Considerations:      

Recyclability Embodied energy Carbon Fooprint ESD strategies; eg solar energy wind energy

4 Structural Joints: 

Roller Joints: Allow rotation but resist translation in a direction perpendicular into or away from their faces Pin Joints: Allow rotation but resist translation in any direction Fixed Joints: Maintain the angular relationship between the joined elements, restrain rotation and translation in any direction Source: Cheng, 2008, Building Constructing Illustrated, 2.30 Joints & connections

Task Description: Week 2's task similar to week 1's involved building a structure that supported itself as high as possible whilst doing so in the previous groups of week 1. However, this structure was to be made out of no more than very thin long (50cm approx) pieces of balsa wood, sticky tape, and pins.

Our first step was to create a base, and so we came to the decision to cut up the this pieces into three to form a triangle. We were able to hold the triangle together through pins and sticky tape. Our next step involved using three of the longer pieces of wood and linking them between two of our made triangles. For stability we decided to cross over the long pieces so that it appeared to form two touching triangular pyramids, applying sticky tape again to the point of friction where the three pieces crossed over. After making this one model, consisting of the two triangles attached together by the long pieces we repeated this process 4 times, simply using sticky tape to hold each model together. The task was in practise quite difficult, however the group once again did the best in class as it was able to reach the roof but do so with much less aid of balance assisted by the roof in comparison to the other groups whilst also being a more stably sound structure as it did not crumble or break. The diagram on the following page illustrates in closer detail the structure used and how it was put together
