Given a reinforced concrete building design with a rectangular footprint of 50m x 20m, 5 stories high, and a 3m thick foundation, using the ACI 318-19 code, calculate the required rebar diameter and spacing for the columns and beams to withstand a seismic load of 0.3g, considering a soil type of medium-stiff clay, and provide a detailed report on the structural elements' capacity and potential failure modes, including a comparison of the results with the equivalent static force method and the response spectrum method.

For a water distribution network consisting of 15 nodes, 20 pipes, and 2 pumps, with a total demand of 5000 m3/h, using the EPANET 2.2 model, determine the optimal pipe diameters, pump settings, and valve configurations to minimize energy consumption and pressure drop, while maintaining a minimum pressure of 20 psi at all nodes, and provide a sensitivity analysis of the results with respect to changes in demand, pipe roughness, and pump efficiency, including a comparison of the optimized solution with the current network configuration.

Using the SUMO 1.10.0 simulator, model a 4-lane highway with a length of 10km, 2 on-ramps, and 2 off-ramps, with a traffic volume of 2000 vehicles per hour, and evaluate the impact of varying the lane change rules, speed limits, and ramp metering strategies on the overall traffic flow, congestion, and travel times, including a comparison of the results with a calibrated VISSIM 2020 model, and provide recommendations for optimizing the traffic signal control and dynamic lane management.

For a proposed embankment design with a height of 10m, a base width of 20m, and a side slope of 2:1, on a soil profile consisting of 2m of clay overlying 5m of sand, using the PLAXIS 2D 2020 model, assess the soil stability and deformation under various loading conditions, including self-weight, traffic loads, and seismic excitations, and evaluate the effectiveness of different soil improvement techniques, such as preloading, geogrid reinforcement, and grouting, in enhancing the soil's bearing capacity and reducing settlement, including a sensitivity analysis of the results with respect to changes in soil properties, water table level, and loading magnitude.
