CONSTRUCTION LOG BOOK
Tutorial week 1-‐ Stewart Brooks Loads are represented as arrows. A load will take the most direct route to the ground. Landscape is the fundamental background to the constructed city. A sense is the direction of a force-‐ direction and sense work together. Compression is a characteristic of mass consumption. Forces are defined by direction and magnitude. We use scales to represent larger elements in a smaller format, smaller elements in a larger format and for practical reasons. E-‐tutorials Loads: Dead loads-‐ the permanent loads of the structure Live loads-‐ something that can be applied
Not sure what kind of accompanying pictures to put here???? Key terms Load path: A path that seismic forces pass through to the foundation of the structure and, ultimately, to the soil. Masonry: Stone or brickwork, the work done by a mason. Compression: The act or process of compressing or the state of being compressed. Reaction Force: Newton’s Law states that for every force acting on a body, the body exerts a force having equal magnitude and the opposite direction along the same line of action as the original force. Point Load: A load concentrated over a very small or tiny area. Beam: A horizontal member spanning and opening or carrying a load.
TOWER MAKING
To begin our tower we decided to make a substantial sized base to ensure it would be built on solid foundations. We chose a width of three blocks which seemed appropriate at the time to allow us to taper the tower inwards, however in retrospect such a bulky and wide base in general was probably not necessary, as it used up most of our resources on the lower levels! We used a stretcher bond style to stack the blocks as we believed this would be the best way to ensure that the load would transfer down to the towers foundations even when the structure began tapering inward as it got higher. After the fifth story we decided to reduce the width to only two blocks across. This was in an effort to save time in the building process as well as reducing the amount of blocks we were using. This proved to be a little more effective and we began to catch up with some of the other towers in our room, whose groups seemed to have decided to build theirs much taller and slimmer in stature.
In order to address the problem of ensuring that the object specified by the tutor (in our case a green dinosaur) could fit through an opening in our structure and back out again we measured the dinosaur in terms of the blocks we were using and then one member of our group built that side of the structure to ensure that the dinosaur could fit easily. This was a major concern for us as we were worried about whether or not the structure would still be able to self support with a chunk of it missing for the doorway. After ensuring that the dinosaur was able to enter, therefore enabling us to meet the requirements, we were running out of time and once all our blocks had been used we began to experiment with how much of our structure we could take apart before in began to crumble. We were for the most part really surprised at how self supporting we had built our structure to be, which made us realize we could have maybe used a third or even half the amount of blocks on many parts. If we built this same structure again we decided a few messages would be: -‐using less blocks on the foundations of the building as we still needed it to reach a certain height -‐spend less time on the design process and more time building.
Week 2 Lecture
Demonstration of force/compression forces By putting four straws together as legs the structure is able to withstand more pressure and leads to more stability. The structure is also able to withstand more when the legs are completely straight. With shorter legs in theory the structure should be able to withstand a little bit more however the legs proved to be a little bit less stable. Angular structures seemed to be the most stable out of the different types that were constructed. Week 2 e-‐learning:
Structural Systems Solid systems-‐ -‐Have particular kinds of structural actions associated with them: -‐shell/frame/skeletal systems -‐hybrid systems “compression” Skeletal systems-‐ are a very very efficient way of transferring loads downwards.
Membrane structures-‐ very common in sports stadiums
Construction Systems Considerations: -‐ Performance requirements -‐ Aesthetic qualities -‐ Economic efficiencies -‐ Environmental impacts
Construction Joints Roller joint: -‐loads transferred directly downwards, but if load comes from any other direction, roller section of the joint can move to cope with these pressures. Pin joints: -‐modes of action can be in two directions *look up pin joints in Ching for more info Fixed joints -‐bending can occur in structure due to stress on the joints from different pressures and no leeway able to be given within joint. A crane is a “truss”-‐ triangulation.
Framework for analyzing form -‐tectonic technique strategies form the DNA of a building -‐column and wall-‐ the arcade (two parallel vertical planes). Point and plane: -‐things begin at a point, which then becomes a plane, the plane then folding or bending to become a volume. A system can be defined as: An assembly of interrelated or interdependent parts forming a more complex and unifidied whole and serving a common purpose. ESD-‐ Environmentally Sustainable Design +thermal mass +solar energy +water harvesting +night air purging A façade of a building is usually considered part of the enclosure system.
TOWER BUILDING WEEK 2 This week we had to use balsa wood and glue to create the highest structure we could. A member of our group kindly cut up the wood so that we were able to start constructing as soon as the time started. He had sliced the wood very thinly which allowed us to have 40 pieces however some of them were not very stable whatsoever. As a group the planning process took us longer than for the previous week due to the fact that we were determined to learn from last week and concentrate on building height instead of worrying too much ensuring our structure was super stable. We discussed a few possible shapes for our structure to take before deciding on a triangle base with triangular reinforcements on each level to ensure the structure could support itself. This proved to be effective and as each member of the group found a job for ourselves we began building quite quickly. We decided on two triangles of 60x60x60cm for the base and first level, followed by 40x40x40cm for two levels then finally 20x20x20.
