The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...

System Identification of a Large Structure Using Pseudo-Dynamic Test Data
This paper deals with structural modeling and the determination of optimal nonlinear models by applying system identification techniques to inelastic pseudo-dynamic test data from a full-scale,...

Characteristics of a Structure-Foundation System
The dynamic characteristics of the structure-foundation system of a 1/4 -scale nuclear power plant containment model is studied using seismic records. The model structure is treated as...

Strong-Motion Records from Buildings
Since the establishment of the California Strong Motion Instrumentation Program in 1972, over 90 buildings have been instrumented extensively to measure their response during earthquakes....

Seismic Evaluation of a Tall Reinforced Concrete Frame Building
Accelerations at basement, fifth and tenth floor levels of a reinforced concrete apartment building were recorded during the October 1st, 1987 Whittier-Narrows earthquake. These accelerations...

Seismic Load Effects on a Scaled Model Structure
A long term observation on a scaled steel braced frame model with intentionally reduced seismic strength is ongoing since 1983. This paper examines the seismic load effects of two earthquakes...

Analysis for the Seismic Response of Liquid Containers
An analytical model is presented for the nonlinear response of fluid containers whose bottom may separate from and lift off their foundation, during base excitation. First, the hydrodynamic...

A Damage Model for Reinforced Concrete
The damage index developed by the authors models concrete damage as a low-cycle fatigue phenomenon. By quantifying the energy dissipated as a fraction of the total energy dissipation capacity,...

SDOF Structural Response Model Accounting for SSI
This paper outlines the theory associated with single-degree-of-freedom (SDOF) structural response models which account for soil-structure interaction (SSI) and evaluates the performance...

The Model Cleanup
Standards for hazardous waste site cleanups may be inappropriate or inadequate to protect the public health. Civil engineers responsible for remediation decisions need to know about the...

Structures for Enhanced Safety and Physical Security
This book presents the state-of-the-art in the general subject of structures for enhanced safety and physical security. The technical papers written are by engineers and researchers who...

Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...

Numerical Modeling of Interface Behavior for Drilled Shaft Foundations Under Generalized Loading
To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed...

Subgrade Models for Soil-Structure Interaction Analysis
Historical development of improvements to Winkler's spring subgrade model are traced. The improvements consist of various ways to provide shear coupling between the springs....

Beams on Elastic Foundations: A New Approach
Using the Vlasov model, Vallabhan and Das have developed an effective iterative technique to solve the beam-on-elastic-foundation problem where the soil is assumed to have a uniform thickness...

A Geotechnical Analysis System with Applications for Drilled Shaft Foundations
The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several...

Ultimate Capacity of Deep Foundation by a Rigid-Plastic Analysis
This paper is concerned with the determination of the axial ultimate capacity of a rigid pier on the basis of the theory of perfect plasticity. As an application of the upper bound theorem...

Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...

Axial Capacity of Pressure-Injected Piles: A Cavity Expansion Model
The application of cavity expansion theory to the development of a mathematical model for predicting the ultimate axial capacity of pressure-injected piles in cohesionless soils is presented....

Computer Utilization in Structural Engineering
This volume contains the papers presented at the 1989 Structures Congress sponsored by the Structural Division of the American Society of Civil Engineers that deal directly with the application...
