MA to ARMA Two-Stage Monte Carlo Simulation
A prior autoregressive (AR) model can be the basis to obtain a quite eficient and reliable subsequent autoregressive moving average (ARMA) approximation. The design of the AR system which...

Random Vibrations of Geometrically Nonlinear Finite Element Structures
A finite element formulation combined with stochastic linearization method is developed to study the large amplitude vibration characteristics of structures subjected to random loadings....

Variability Analysis of Bridge Responses Using the Semi-Continuum Method
The semi-continuum method is used for Monte Carlo simulation of a large number of bridges. It is confirmed that the mean values of responses can be obtained deterministically, and their...

Importance Sampling in Structural System Reliability
In structural system reliability analysis, it is frequently necessary to resort to Monte Carlo simulation (MCS). This paper focuses on Importance Sampling, an advanced MCS method, which...

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...

Reliability of Large Structural Systems Under Time Varying Loads
Time invariant reliability analyses of structural systems are generally carried out by using the well-known failure mode approach. To include the time varying effects of loads, concepts...

Approximate Reasoning in Engineering Decision Analysis
In this paper, the concept and methods of approximate reasoning are reviewed and discussed. The methodology of combining precise results of exact analysis, approximate solutions of exact...

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...

Markov Approximation to Fatigue Crack Propagation
The distribution of the time required by a crack to reach a specified length and the distribution of the crack size itself are determined. To this end, the fatigue crack propagation growth...

Challenges in Stochastic Structural Mechanics
Currently there are the emerging developments in stochastic computational mechanics, which includes stochastic finite elements and its applications in problems of random systems and random...

Living with a Macintosh in an IBM World
The Macintosh computer is widely praised for several characteristics: high resolution graphics, common program user interface, user friendliness including extensive use of a mouse, and...

Conflict Management Task Committee Approach
The Task Committee on Conflict Management (coordinated by the Social and Environmental Objectives and Impacts Committee, WRPMD), was established to develop guidelines for use by water...

The Conservation Foundation's Handbook on Resolving Water Resource Disputes
As part of a cooperative effort with the ASCE's Water Resources Planning and Management Division, The Conversation Foundation is working to develop a handbook for resolving...

The Development of a Design for a Breakwater at Keflavik, Iceland
A breakwater design was developed to be built using local quarried rock and relatively simple construction methods. The design significant wave height was 5.8 and the maximum depth of...

High Strength High Rise
For the sixth time in history, a structure billed as the world's tallest concrete building (over 950 ft) is under construction in Chicago. The contractors describe the structure...

Trenchless Techniques for Pipeline Installation, Renovation and Replacement
New construction methods have been developed primarily in Europe and Japan for underground pipeline work. The new methods, known as trenchless techniques, are primarily used when existing...

New Pavement Materials
New materials and construction techniques are constantly being evaluated to extend pavement life and to improve overall performance of highway and airfield pavements. To be beneficial,...

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...
