Exercise A certain site is underlain by clay. A proposed building for this site having a 500 kN column load (including the weight of foundation) is designed to be supported on a surface square footing. A field plate loading test was performed using a square plate of size 30 cm, Figure 1 displays the pressure- settlement curve, from which the ultimate capacity of the plate was 180 kN/m2. Answer the following questions: According to the plate loading test result, considering a factor of safety of 2 against vertical bearing capacity and the allowable settlement of 2.5 cm for design requirements, determine the minimum footing size to meet the requirements and the condition which governs the design (bearing capacity or settlement).

A certain site is underlain by clay. A proposed building for this site having a
500 kN column load (including the weight of foundation) is designed to be
supported on a surface square footing. A field plate loading test was
performed using a square plate of size 30 cm, Figure 1 displays the pressure-
settlement curve, from which the ultimate capacity of the plate was 180 kN/m2.
Answer the following questions:
According to the plate loading test result, considering a factor of safety of 2
against vertical bearing capacity and the allowable settlement of 2.5 cm for
design requirements, determine the minimum footing size to meet the
requirements and the condition which governs the design (bearing capacity or
settlement).
