Use Bishop's definition of effective stress for the silt layer, assuming x =S.. Assume a value of G. = 2.65 and that the gravimetric water content of the silt below the water table is 20%.

The height of the parapet above the roof is 2 feet. The walls are to be constructed of 8-inch CMU and are to be fully grouted. The building is assigned to SDC D, and therefore, the walls have to be special RM shear walls according to TMS 402. There are 6 shear walls to resist the lateral seismic force along one principal axis of the building and 4 shear walls along the other axis. The corner walls are flanged walls meeting the requirements in Sec. 5.2.3 of TMS 402-22. The columns carry only gravity loads and no lateral seismic forces. The floor and roof diaphragms are relatively flexible in out-of-plane bending compared to the in-plane flexural stiffness of the walls, so that you can ignore the coupling moments and shear forces exerted by the diaphragms on the walls. However, the in-plane stiffness of the diagrams is high so that their planar deformation can be ignored.…arrow_forward

Determine the average travel time (walking + in-vehicle) of passengers. c. Simplify the above equation when N is large enough (approximating N-1/2 by N-1).
