2. Using the Green-Ampt Model, compute the infiltration rate, f,
and cumulative infiltration, F, after one hour of infiltration
into a sandy clay loam soil. Assume initial moisture
conditions are midway between the field capacity and wilting
point and that water is ponded to a small but negligible depth
on the surface.

partition load is 1.8 kN/m². The live load on the floor is 2.4 kN/m². The beams cross section dimension is
300mmx600mm. Assuming the unit weight of concrete is equal to 24 kN/m². It is required to:
a) Show tributary areas for all the beams on the plan;
b) Calculate the load carried by beams B1 (on gridline A, between 1 and 3), B2 (on gridline B, between 1 and
3)and B3 (on gridline 3, between A and C);
c) Calculate the load carried by column C1 per floor (ignore the self weight of the column).
