Learning Loop Compression and Extension • Is considered as forces o Force is defined by its magnitude and its direction Compression : 2 forces facing the same direction, which pushes an object inwards, resulting in compacting and shortening the length
Extension : 2 forces facing opposite directions, which “pulls’ an object from 2 sides outwards, stretching the object itself Loads Can be divided into 1. Static Load : applied slowly to structure without fluctuating rapidly in magnitude or position1 o Live loads (moving or moveable) o Dead loads (static)
o Occupancy loads o Settlement loads o Ground and water pressure o Thermal stress o Rain and snow loads o Impact loads
2. Dynamic Load : applied suddenly to a structure, rapid change in magnitude and point of application2 o Wind loads (based on the kinetic energy of a moving mass of air) o Earthquake (depending to vibrations on the earth’s crust)

Studio Brick Tower The last activity in week 1 studio was to make a solid, concrete brick tower in small groups of 4 people. The diameter of the tower that we made we considered to be big enough to support the tower, firstly assuming that the tower as it builds up will decrease in the size of its diameter. Goal : To make a building as tall as possible using the materials given Materials : Small wooden bricks
Steps 1. 2. 3.
Our building used variation of patterns differentiated by 1. Thickness 2. The number of wooden bricks used Pattern Our group constructed the tower in
a circular shape, placing the bedside of the brick as the bottom part. As it is the largest area of the brick it will result in a strong base for the foundation of the tower. The brick is stacked vertically to maximize height. The stretcher of the brick is placed as the bottom,
using the width or length of the bed part as the height.
Efficiency of Materials Used • Construction process takes a lot of time, time consuming • Placing of bricks are not always in a precise position • Consistency and thickness of the walls are not always consistent Amount of Materials Used The amount of materials used depends on each pattern and how many layers the pattern goes on. Deconstruction of the Tower
The deconstruction process starts from the bottom of the tower, where the pattern is most firm and stable. Openings were made not until the top most part to still keep the tower intact. By taking parts of the tower off, the load that was supporting one another changed. The load, or downward force from above was then distributed to the other bricks on the sides of the “hole”.
For this reason the hole was made narrow, to keep the distribution of forces in the tower still stable.
We made the “hole” or the opening on both sides bigger and bigger up to the point when the 2 “legs” of the tower could not withstand the downward force and collapsed. Comparing to Other Groups 1. This group’s tower was made using similar patterns to ours. However
the tower was made slightly tilted to one side. The fact that it is tilted actually becomes an advantage, as when it is deconstructed from one side it does not affect the stability and distribution of the tower. It was already tilted in the first place so even when parts of the tower were taken off, the tilted part can still hold. The tower was made using minimum use of materials, not very thick. 2.
This group’s tower was made the shortest out of the others. However it was made with the firmest base and the most amounts of materials. Its foundation if the tower was continued to be built would most likely be the one that would withstand the most amount of load.
Glossary Appendix Force : influence which tends to change the motion of an object Compression : the application of balanced inward forces to different points on a material or structure Load : Forces, deformations, or accelerations applied to a structure or its component Mass Construction : A building construction approach using masonry, adobe, or other building materials that can lessen the extremes of diurnal flux, especially in arid climates
Beam : a structural element that is capable of withstanding load primarily by resisting bending Frame : a structural system that supports other components of a physical construction
