Concept explainers

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.

10 In a channel of rectangular cross section with a slope of 1 in 1000, the discharge is to be 1,4 m³/s when the channel is running full. Its depth is half as its breadth. If the channel is roughly excavated, the coefficient of discharge C is 27 in SI units, and the Chezy formula is V = C √(Rs). If the bottom and side slopes are finished smoothly, C = 81 (R = hydraulic radius, s = slope) Assuming the cost of excavation /m³ is twice the cost of smooth finishing /m² Compare the costs of the two types of channels.
