Development of a Mixed Numerical Method for Piled-Raft Analysis Using International Codes

“…The recorded settlement at the center of the raft in March 1990 was 8.5 [cm] (Katzenbach et al, 2000), while the recorded settlement in 2001 was 14.4 [cm], (Sales et al, 2010, andEslami et al, 2011). The expected final settlement, in this case, would be between 15 [cm] and 20 [cm], (Sommer & Katzenbach, 1990).…”

“…These instruments record raft settlements, raft contact pressures, and loads on pile heads and along the pile shafts. The behavior of Messeturm had been studied by many authors, such as (Sommer & Katzenbach, 1990;Katzenbach et al, 2000;Reul & R&olph, 2003;Chow & Small 2005;Sales et al, 2010;Eslami et al, 2011). Figure 8 shows the Messeturm piled-raft as given by Chow & Small 2005.…”

“…While that for reloading is: According to (Sommer & Katzenbach, 1990), the undrained cohesion cu of Frankfurt clay increases with depth from cu=100 [kN/m 2 ] to cu=400 [kN/m 2 ] in 70 [m] depth under the clay surface. Poisson's ratio of the soil is taken as νs = 0.25 [-].…”
