1. Structural Member Design

For a 50-foot span steel beam in a commercial warehouse supporting automated conveyor loads (150 psf live), design the section to resist combined bending and torsion while limiting deflection to L/400—evaluate lateral-torsional buckling and propose web stiffeners if needed, using AISC LRFD methods.
In a military hangar with wood glulam columns under 200 kip axial loads and blast overpressure (5 psi), analyze compression capacity considering moisture effects and eccentricities—suggest fiber wrapping for enhanced ductility per NDS standards.
Design a prestressed concrete girder for a mid-rise office bridge atrium, accounting for long-term creep and camber—how would you adjust tendon eccentricity to balance dead load moments without exceeding ACI stress limits?

2. Connection Design

Propose bolted end-plate connections for roof joists in a curved commercial arena roof, handling uplift winds (60 psf) and thermal expansion—analyze prying forces and bolt pretension to prevent fatigue failure over 10^6 cycles.
For a steel-to-concrete beam pocket in a military vehicle maintenance bay, design embedded anchors to transfer 150 kip shear under impact loads—evaluate pullout capacity per ACI Appendix D and incorporate corrosion protection for humid environments.
In a high-seismic commercial tower, detail a base plate for a moment-resisting frame column (500 kip axial + 200 kip-ft moment)—compute anchor rod tension and suggest shear keys to achieve full fixity while accommodating construction tolerances (±1/4 inch).

3. Plate, Slab, and Foundation Design

Design a two-way reinforced concrete slab for a hospital floor (100 psf live load) with column spacings up to 30 ft—address punching shear around drops and propose temperature reinforcement to control cracks, ensuring deflection < L/360 per ACI.
For a slab on grade in an arctic military depot supporting heavy artillery (500 psf), calculate thickness and joint spacing to resist frost heave and thermal curling—integrate fiber reinforcement and evaluate subgrade modulus effects on cracking.
In a coastal commercial high-rise, design a mat foundation on piles for liquefaction-prone soil—analyze differential settlement under seismic loads and optimize pile layout to minimize bending moments in the raft.

4. Bracing and Stability Systems

Evaluate X-bracing versus eccentric bracing in a steel-framed commercial office for a high-wind zone (120 mph)—compute stiffness contributions to reduce story drift to H/500 and assess fatigue from vortex shedding.
For a buried military command bunker, design concrete shear walls as a stability system against lateral earth pressure (50 psi)—incorporate damping devices to mitigate earthquake resonance and validate with nonlinear dynamic analysis.
In a tall wood-framed residential tower retrofit, propose tension-only bracing to prevent soft-story collapse—analyze P-Delta effects and suggest hold-down anchors to handle uplift in seismic events.

5. Composite and Modular Systems

Design a composite steel-concrete beam system for a data center floor with sensitive equipment (vibration limit 0.5 mils)—optimize shear stud spacing for 75% composite action and evaluate fire resistance enhancements.
For deployable military modular barracks using prefabricated wood-steel hybrids, detail inter-module connections for rapid assembly (under 24 hours)—assess shear transfer and redundancy under blast loads equivalent to 100 lb TNT.
In a sustainable commercial retrofit, propose modular CLT panels integrated with steel trusses—calculate load-sharing ratios and thermal bridging effects to achieve net-zero energy goals.

6. Advanced and Specialized Design Topics

Analyze progressive collapse in a multi-story commercial mall under column removal scenarios (per UFC 4-023-03)—design tie forces and alternate paths, incorporating smart sensors for real-time monitoring.
For a military offshore platform, design against wave-induced fatigue using finite element modeling—evaluate corrosion fatigue in steel members and suggest cathodic protection strategies.
In an urban high-rise, integrate resilient design for flood events by elevating critical systems—assess hydrodynamic loads on foundations and propose adaptive base isolation for combined seismic and scour effects.
