Maximum shear modulus of a Brazilian lateritic soil from in situ and laboratory tests
L. Décourt, J.M. de Camargo Barros, O.C.B. Gandolfo, Fernando Damasco Penna
A lateritic soil in Santo André investigated with SPT-T, crosshole, SDMT, CPTu and laboratory tests for the foundation design of a building. The maximum shear modulus obtained showed stiffness well above what correlations developed for temperate-zone soils would predict.

Predicted and measured behavior of a tall building in a lateritic clay
L. Décourt, C. Grotta Jr., A.S. Damasco Penna, G.C. Campos
A 25-storey building on lateritic clay, with foundations designed by settlement rather than capacity. A footing load test up to conventional failure and column settlements measured during construction: under 10 mm, even with bearing pressures around 1.2 MPa.

Comportamento de estacas pré-moldadas de concreto em solo residual de gnaisse de muito baixa compacidade
Antônio Sérgio Damasco Penna
In Duque de Caxias, driven precast piles stopped far shallower than expected, with their tips bearing on soil of only 4 to 8 SPT blows. Dynamic monitoring, static load tests and SPT-T, CPTu and DMT testing explain the behaviour, traced to two geological faults.
