Abstract

This paper examines the behavior of a building constructed in 1960 and subject ever since the end of its construction to considerable total and differential settlements in time. Monitoring of the building revealed an increase in the settlement rate during the first years of the 1990s, such as to require underpinning with micropiles in 1992. In the first part of the paper, the evolution of settlements until the beginning of the restoration is analyzed, and real and anticipated behaviors are compared. In the second part, the behavior of the building during and after micropile underpinning is explained. Back-analysis was carried out, adopting tridimensional finite element analyses, in order to interpret behavior before and during underpinning.

Behavior of the Underpinning of a Building in Venice

St. Louis, Missouri

This paper examines the behavior of a building constructed in 1960 and subject ever since the end of its construction to considerable total and differential settlements in time. Monitoring of the building revealed an increase in the settlement rate during the first years of the 1990s, such as to require underpinning with micropiles in 1992. In the first part of the paper, the evolution of settlements until the beginning of the restoration is analyzed, and real and anticipated behaviors are compared. In the second part, the behavior of the building during and after micropile underpinning is explained. Back-analysis was carried out, adopting tridimensional finite element analyses, in order to interpret behavior before and during underpinning.
