Challenges
Hyper-Static Arch Resilience Protocol
Design and construct a structural arch spanning exactly 30cm that must support a fluctuating load of 5kg while resisting lateral sway induced by a dynamic oscillatory force. You must prioritize the calculation of thrust line stability and demonstrate how the structural geometry accommodates the bending moment under asymmetric loading conditions. The final evaluation will focus on the deflection-to-load ratio and the efficiency of the force distribution path within your material constraints.
Seismic Resiliency in Tall Modular Structures
Design and construct a vertical structure at least 40cm tall that incorporates a base-isolation or dissipative dampening system to withstand lateral impulse loading. The structure must maintain vertical alignment and structural integrity while subjected to a 10-second simulated harmonic vibration test mimicking specific seismic wave patterns. You must provide a brief technical report calculating your anticipated natural frequency and total mass distribution.
Seismic Resilience of Modular Lattice Towers
Design a self-supporting vertical structure at least 40cm tall that utilizes a braced-frame geometry to resist lateral shear loads. Your structure must support a 500g eccentric mass at the apex while enduring a 30-second simulated harmonic oscillation test at varying base frequencies. You must prioritize material efficiency and calculate your displacement-to-height ratio before and after the vibration test.
Tension-Compression Hybrid Truss Optimization
Design a truss system that maintains structural integrity while spanning a 40cm gap and supporting a 5kg dead load at the center point. You must minimize total material mass while maximizing the stiffness-to-weight ratio to prevent deflection exceeding 5mm. Document the calculated failure points for each joint under maximum stress to evaluate the load distribution efficiency.
Dynamic Seismic Mitigation for Tall-Structure Prototypes
Design and construct a vertical structure at least 60cm in height that must withstand a 30-second sustained horizontal oscillation test at a frequency of 2Hz. You must incorporate an integrated, non-powered tuned mass damper (TMD) system to minimize structural deflection at the apex during excitation. Success is measured by the ratio of structural stiffness to the mass of the damping system while maintaining integrity under base-load displacement.
