Refinement of the Strain Wedge Model Program
This report describes the computer program of the strain wedge model, a program that characterizes the behavior of single piles, pile groups, and pile caps embedded in uniform or layered soils when subjected to lateral ...
Undrained Lateral Pile and Pile Group Response in Saturated Sand
Strain wedge(SW) model formulation has been used, in previous work, to evaluate the response of a single pile or a group of piles (including its pile cap) in layered soils to lateral loading. The SW model approach provides ...
Simple Bridge Models for Earthquakes and Test Data
A simple nonlinear model (called the Q-Model) for seismic displacement history analysis of reinforced concrete plane frames was implemented on a Commodore 64. This manual presents a brief description of the model (see the ...
Determination of In-Situ Footing Stiffness Using Full-Scale Dynamic Field Testing
This report presents the results of an experimental and analytical study, which was conducted on three footings of an existing bridge in order to determine their in-situ stiffnesses. The bridge is located on Interstate 80 ...
Soil-Foundation-Structure Behavior at the Oakland Outer Harbor Wharf
This paper discusses the use of CSMIP records at Oakland Outer Harbor Wharf (along with records from Yerba Buena and Treasure Island) to study the free-field motions at Oakland Outer Harbor, both at shallow depth and to ...
Report and User Manual on Strain Wedge Model Computer Program for Files and Large Diameter Shafts with LRFD Procedure
Based on the Strain Wedge (SW) Model Analysis, the computer program SWM6.2 allows the assessment of: Lateral/axial response of isolated (single) pile and large diameter shaft, i.e. pile/shaft classification (short, ...
Seismic Lateral and Rotational Pile Foundation Stiffnesses at Cypress
The Cypress Viaduct, located some 60 miles from the earthquake epicenter, suffered catastrophic structural damage during the 5 to 10 seconds of strong shaking of the Loma Prieta earthquake of October 17, 1989. While much ...
Liquefaction and Residual Strength of Loose Sands from Drained Triaxial Tests
The state of knowledge with regard to static and cyclic liquefaction has progressed tremendously since the mid-1960s. In fact, it is generally accepted, based on the steady-state concepts of Casagrande, Castro,and Poulos ...
Analysis of Laterally Loaded Long or Intermediate Drilled Shafts of Small or Large Diameter in Layered Soil
Strain wedge (SW) model formulation has been used, in previous work, to evaluate the response of a single pile or a group of piles (including its pile cap) in layered soils to lateral loading. The SW model approach provides ...
