According to the analysis method introduced in Part 1, numerical calculations on model cases are performed. The model of building and ground is shown in Fig. 1. The building on pile foundation has 10 stories and the plan 4 spans×11 spans, whose structure is constructed with reinforced concrete or steel. The composition of strata and soil properties are decided from the condition of the ground existing generally in the west of Osaka city. The settlement and the reaction force on each footing of the model in the process of consolidation of the diluvial clay stratum are calculated under the condition that the coefficient of volume compressibility m_v and the coefficient of consolidation c_v are constant and the condition that m_v and c_v are variables. As the results of numerical calculation, the following conclusions can be devised. 1. The effects of structural rigidity and creep of concrete are considerably remarkable in the distributions of settlement, differential settlement and reaction force on footing in the model structures, especially in reinforced concrete structure. 2. The bending moments on some members of model structures are large enough to occur plastic hinges. 3. The velocity of settlement of each footing in the case that m and c are variables than in the case that m_v and C_v are constants. 4. The final values of settlement, differential settlement and deviation of reaction force on footing from the average value of load on all footings are smaller in the case that m_v and c_v are variables than in the case that m_v and c_v are constants.
