A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...
Properties in Sensitivity Coefficients of Framed Structures
This paper presents a special relationship among sensitivity coefficients of static response, natural frequency and mode. The relationship is that the sum of sensitivity coefficients in...
Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
Modeling and Analysis of Shafts and Tunnels for the SSC
A brief overview of the Superconducting Super Collider Project (SSC) is presented followed by a discussion of the 3D modeling and finite element analysis of tunnels and shafts. The sequential...
Using Finite Element Analysis to Derive the Coefficient of Subgrade Reaction
The coefficient subgrade reaction is a concept used to generate spring constants which are commonly used to model the foundation subgrade in the analysis of mat foundations. This paper...
Developing an Integrated Database Structure for the Lifecycle of Precast Concrete Projects
