QUESTION 1 / summary of project
The objective of this project is to construct a structural model resembling a tower using spaghetti and blue tack, with specific dimensional constraints, and subsequently subject it to simulated seismic conditions. The primary design parameters dictate that the tower must attain a minimum height of 60 centimetres while maintaining a maximum base size of 30 centimetres. The construction materials, spaghetti, and blue tack, will be procured within a budget constraint of $60. Each piece of spaghetti is priced at $1, and blue tack is priced at $1 per gram.
The experimental procedure involves the assembly of the tower, mimicking the architectural challenges faced in real-life seismic-resilient structures. Upon completion, the tower will undergo seismic simulation by subjecting it to controlled shaking, simulating the effects of an earthquake. The structural integrity and stability of the tower under these conditions will serve as a practical analogy to the challenges faced in designing earthquake-resistant buildings.
This project holds significance in providing a hands-on learning experience, shedding light on the complexities involved in constructing real-world structures capable of withstanding seismic forces. It draws parallels to earthquake-prone regions such as Japan, where engineered structures are strategically designed to endure the dynamic forces exerted during seismic events along tectonic plate boundaries.
QUESTION 2 / Analysis of engineering process
Following the completion of the earthquake-resistant tower experiment using spaghetti and blue tack, a comprehensive evaluation of the outcomes reveals promising success. The tower demonstrated remarkable stability during the simulated earthquake, withstanding the seismic forces without collapse.
The chosen materials, spaghetti, and blue tack played pivotal roles in the positive outcomes. The spaghetti, adequately reinforced, provided robust structural integrity, effectively withstanding the simulated seismic forces. Blue tack, utilised for connecting and reinforcing the structure, proved successful in securing joints and distributing support evenly. Observations during the earthquake simulation indicated minimal swaying of the tower, showcasing its resilience.
While the experiment was successful, continuous improvement is always a goal in scientific endeavors. To further enhance the success achieved, refinements are proposed. Experimenting with additional techniques to reinforce the spaghetti can be explored, including bundling multiple strands or testing alternative materials for even stronger supports. Attention to detail in improving connections between spaghetti pieces using bluetack remains crucial to ensure continued success in securing joints and distributing support.
Structural design modifications, though effective in the current experiment, could still be refined for optimal performance. Incorporating the triangular shapes for stability and adding diagonal braces strengthen the tower’s resilience, whereas in our first prototype we did not have this. Consideration of weight distribution on the tower should be maintained to ensure an even spread of stress during seismic events.
To continue the success achieved, controlled testing and iterative improvements are recommended. Adjusting one variable at a time, such as the height of the tower, the amount of blue tack used, or the thickness of the spaghetti, allows for a systematic understanding of their individual impacts. Iterative testing involving multiple trials after implementing changes will further solidify the success observed.
