The drawing shows the beam (B) and girder (G) layout for the third floor of a commercial building.
The live load (LL) for the flow is 45 PSF and the dead load (DL), which consists of a 4" thick
concrete slab weighs 50 PSF. For now, we will neglect the weight of the beams/girders.

Use the method of virtual work and show all working.arrow_forwardYou are an engineer designing an aeration tank for a wastewater treatment plant receiving municipal waste. The activated sludge system (aeration tank and secondary clarifier) you design needs to remove 85% of the incoming BODs from the primary effluent, giving a final concentration of 30.0 mg BOD5/L exiting the system. Your design will maintain a concentration of 2500 mg VSS/L and F/M ratio of 0.5 g BOD/g VSS d in the aeration tank. In an effort to keep the waste activated sludge low in water, only about 0.1% of the primary effluent flow (Q) exits the WAS line. The secondary effluent has a flow rate of 9990 m³/d. What volume (in m³) will the aeration tank need to be? Write out all equations and state any assumptions as needed. Primary effluent: Aeration tank V, X, S Secondary clarifier Secondary effluent: Q.
