Earthquake Resistant Design of a Masonry Structure
1.0 Design of a masonry structuresThe goal of this experiment is to understand the process for building civil structures and to
comprehend the behavior of structures during earthquakes. Construction companies should beformed with an engineer, an architect, and a builder. This construction company will be hired by abuilding owner to design and construct a new structure.
Form groups of 4, and each make person responsible for one of the following jobs:
� Building Owner: The goal of the building owner is to have a building that can be rented for the most money.
� Architect: The job of the architect is to make sure that the building is beautiful.
� Engineer: The engineer will make the building strong to survive the strongest possible earth-quake.
� Builder: The builder will construct the building based onthe designs by the architect and the engineer.
2.0 Design and construction process� Meet with your group, decide on a name for your company, and agree upon your respective
jobs.
� Sketch your ideas for the building on paper. Come to agreement on how your building project will proceed before starting construction. The builder should never allow construction to get ahead of the architect�s and engineer�s design.
� Build the structure according to the ideas sketched on paper.
2.1 Design parameters� Use cardboard as the foundation for your building.
� The maximum dimensions of the building are 10 by 5 blocks in the base, and unlimited number of floors.
� Floors with more room can be rented higher. Therefore, the bigger the floors the more money the building owner can get.
� People like to have a good view of the city from this building. The floors with more windows (or bigger windows) can be rented higher.
� From top floors the view is even better than from lower floors. The higher the floor the higher the rent that could be charged.
� Buildings have to be maintained. A maintenance cost should be paid to paint the building. This cost should be deduced from the rent cost.
The income of the building is rent minus maintenance

3.0 Building materialsThe building will be constructed using the following materials
� Sugar cubes: Sugar cubes will be used as bricks
� Peanut butter: Peanut butter will be used to connect one brick with the ones next to it.
� Cardboard: The floors will be built using cardboard
4.0 TestingThe buildings will be tested in an earthquake simulator. The day of the testing each group
will have a 3 minute presentation about their building. In the presentations the group should dis-cuss the considerations that they had for the design and construction of the structure and the prob-lems they faced.
Before testing the structures, the most attractive building, the building with more income, andthe tallest building will be selected. Then, each building will be tested in the earthquake simulator.
