Prediction of Settlements of Footings on Sands: Accuracy and Reliability
Serviceability limit states are controlled by the deformations that a specific structure can undergo. This aspect involves a correct design of foundations to ensure that the supported...
A Procedure for Predicting Seismic Deformation of Earth Structures
This paper presents an analysis procedure for predicting the earthquake induced displacements of earth structures. The procedure is an extension of the simple Newmark method from a single-degree-of-freedom...
Deformation of Sand Foundations Induced by Earthquakes
This paper discusses the deformation of sand foundations during earthquakes based on the experimental results of centrifuge tests. A group of tests was conducted on two types of buildings...
Seismic Settlement of Shallow Footings on Sands
In this contribution, the progressive seismic settlement of shallow footings on cohesionless soils is calculated using a sliding block model. Beyond a critical horizontal acceleration,...
Settlement of a Silo Subjected to Cyclic Loading
The paper presents the vertical settlement values for a corn silo located at Ca' Mello, close to Porto Tolle (Italy), and compares it with the theoretical results obtained using a simplified...
Soil-Structure Interaction During Mining Induced Ground Movements
Mining induced subsidence can result in significant ground deformation, which is generally non-uniform. Although this deformation occurs slowly with small inertial forces, it often results...
Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
Settlement of Large Mat on Deep Compressible Soil
This case history describes the settlement analyses for a large load compensated (floating) mat foundation on a deep deposit of normally consolidated clay of variable thickness. Large...
Long Term Performance of Raft and Footing Foundations Above Clayey Silt
Two multistorey buildings have recently been constructed on a 30-m thick layer of clayey silt in downtown Fredericton, New Brunswick. The Bank of Montreal building is ten storeys high...
Settlement of an Air Cargo Structure on Soft Clay
This paper presents a case history of settlement of a light structure on San Francisco Bay Mud. Despite measured total settlements of 56 to 82 cm, the structure is still functioning 27...
Influence of Flexible Mat on Settlements of Marine Clay
Highly compressible marine clays occur extensively in coastal regions. In lieu of traditional pile or raft foundations in such weak soils, recently a flexible mat system has been developed...
The Influence of Engineering Judgement in the Settlement Analysis of a Test Fill Near Ch?lon-sur-Sa?ne, France
This paper describes the settlement study for a test fill near Chalon-sur-Saone (France). The soil profile at the site comprised a silty clay layer 4.2 m thick. The elevation of the ground...
Design and Installation of a New Settlement-Inclinometer Device
A new miniature settlement-inclinometer device (SID) system has been designed and built at the University of British Columbia for use in monitoring soft soil movements. The great advantages...
Performance of Three Large-Diameter Oil Tanks on Soft Clay
Preloading using a clay surcharge at the proposed locations of 3 large-diameter steel oil storage tanks founded on a 20-m thick stratum of soft Nile-delta silty clay produced about 1.5...
Vertical Displacement Induced in Soil by Conical Shell Foundations
Shells can hold prospect for adoption in foundation engineering only if they can be projected as economical alternatives to conventional flat foundations. Therefore, the initial enthusiasm...
Settlement of Structures Supported on Marginal or Inadequate Soils Stiffened With Short Aggregate Piers
A short aggregate pier system, which was developed to provide an economical alternative to the overexcavation/replacement technique, has been used since 1988 to control settlement of structures...
Down Drag on Friction Piles: A Case History
The down drag settlements experienced by the foundation of a supermarket constructed in 1972 in Gretna-New Orleans, Louisiana are presented. Two different lengths of piles (12.2 m and...
Design of Underpinning Piles to Reduce Settlements
Piles are frequently used to underpin structures which have suffered, or are expected to suffer, damage due to excessive settlement or differential settlement. However, existing methods...
Footing Modulus Near Slopes
A method is described for estimating the footing modulus of shallow spread foundations located near slopes of cohesionless material. The ratio of footing modulus for a shallow foundation...
Settlement and Deformation Response of a Bridge Footing on a Sloped Fill
The problem of settlement of spread footings located within or near granular slopes has been investigated in the laboratory using a large testing facility. Based on these results, footings...
