Response of Two-Span Beam to Spatially Varying Earthquake Excitation
The effect of the spatial variation of strong ground motion should be considered in the analysis and design of large structures such as bridges, lifelines, dams, etc. The stochastic response...
Stochastic Finite Element Analysis of Railroad Tracks
The loads acting on railroad tracks due to the passage of trains and the resisting track parameters have a random character. The purpose of this study is to incorporate the random parameters...
Reliability Study of Randomly Imperfect Beam-Columns
In this study, the effect of random initial geometric imperfections was treated as a set of equivalent random initial forces. This concept enables the direct employment of existing stochastic...
Geosynthetics for Soil Improvement
Geosynthetics have had a tremendous impact on various aspects of soil improvement. In a number of situations which previously had not been technically or economically feasible, geosynthetics...
Parallel and Distributed Processing in Structural Engineering
Parallel processing is emerging as an effective approach to large scale structural engineering computations. The papers included in this book cover vibration analysis using a parallel...
Potassium Fertigation in Drip Irrigated Peppers in Puerto Rico
Three potassium fertigation rates (T1 = 100%, T2 = 60%, T3 = 30%) via trickle irrigation, fertilization rates (T4 = 100%, S1 = 100%, S2 = 50%, S3 = 0.0) and nonfertilization (T5 = 0.0)...
Trace Elements and Pesticides in Salton Sea Area, California
Concentrations of numerous potentially toxic trace elements and pesticides were determined in water, sediment, and biota from the Salton Sea area in southestern California. Comparison...
Finite Element Modeling in Free-Surface Hydromechanics
A finite element semi-discrete approximation is applied to the conservation law form of the two-dimensional, depth-averaged free-surface Navier-Stokes equations governing incompressible...
Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
Generation of Native FE in Lunar Soil
Electron Spin Resonance (ESR) studies on lunar samples produced some unexpected results which led to recognition of the presence of abundant single-domain Feo...
Dynamic Analysis of the Joint Dominated Beam
A method is presented herein to determine the vibration modes of the Joint Dominated Beam. An example of a cantilever beam is selected for this purpose. The truss type beam is analysed...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Progressive Impact Damage Assessment in Composite Pressure Vessels
At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads...
A Visual Approach for Space Systems Designers
This paper discusses computerized tools that may be used by designers as they approach problem solving related to engineering, construction and operations in space. Tools for space system...
An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
