Modified CIMIS Irrigation Scheduling Program
CIMIS, California Irrigation Management Information System, is a program that collects weather data around the state to assist irrigators in planning and scheduling their irrigations....

Reliability of a Frictional System with Uncertainty
In recent years, more emphasis has been placed on the study of random vibration of structures with uncertain parameters. Most of these have dealt with second order statistics of the response...

Unified Approach to Reliability-Based Structural Optimization
The purpose of this paper is to present a unified approach to reliability-based structural optimization. The emphasis is placed on recent developments in the field including optimal design...

Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...

Geologic Assessment of Seismotectonic Hazards
Design and modification of dams require evaluation of potential seismotectonic hazards based on consideration of the historic earthquake record and deterministic evaluation of geologic...

Seismic Response Component in the Risk Assessment of Dams
The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the...

Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...

A Simple Microcomputer Finite Strip Analysis
The development of a finite strip analysis of thin-walled section buckling behaviour is outlined. The analysis uses plate theory for out of plane deflection behaviour and beam theory for...

Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...

Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...

Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...

Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...

Dynamic Simulation of Foundations on Winkler Subgrade
The objective of this paper is to present a dynamic simulation of foundations on Winkler subgrade. The analysis is based on a direct simulation procedure. The structures have been modeled...

Combined Finite Difference/Finite Element Analysis for Soil Structure Interaction
A method for the analysis of buried structures subjected to stress transients is presented. The method combines the finite difference and finite element techniques to provide the analyst...

Lateral Impedance of Contact Pile Foundations
The static and dynamic lateral impedance of pile foundations for which there is continuous contact between the bottom of the pilecap and the underlying soil is investigated. A parametric...

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...

Research Needs to Resist Terrorist Attacks
The task of protecting facilities against terrorist attacks is very much a new problem for the U. S. civilian sector. Guidance as to what steps need to be taken by a municipality or a...

Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...

Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...
