Earthquake Considerations in Earth Dam Design
In 1963, the writer was engaged by the State of California Department of Water Resources to make a study of the influence of the hazard of earthquakes on the design of embankment type...
Piping in Earth Dams of Dispersive Clay (Paper introduced by Norman L. Ryker)
In 1971 Jim Sherard was engaged to investigate the common failure of a group of Soil Conservation Service (SCS) floodwater retarding earthfill dams built between 1957 and 1970, eleven...
Land Use, Transportation and Air Quality Relationships
Increasing land development densities and reducing suburban sprawl is frequently considered as a tool to reduce vehicle miles of travel and resultant air pollution emissions. Two studies...
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...
Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....
Reliability Analysis of Lunar Structures Under Meteoroid Impact
The United States is slowly moving towards lunar base, and possibly Mars base, activities. Design of structures for these bases requires knowledge about loadings and conditions which in...
Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...
Fuzzy Measures in the Knowledge Based Diagnosis of Seismic Vulnerability of Masonry Buildings
Rules based expert systems and fuzzy logic have been employed to increase the speed and the reliability of the survey of masonry buildings, to forecast their seismic vulnerability....
Application of the Sampling Theorem to the Representation of Random Fields
A new parametric model is developed for homogeneous Gaussian random fields based on a generalization of the sampling theorem. The model depends linearly on a finite set of discrete values...
Response Variability and Reliability of Plates Using the Weighted Integral Method
A methodology is introduced to perform both the response variability and reliability analysis of two-dimensional stochastic systems (specifically plates subjected to plane stress or plane...
Stochastic Finite Elements and Reliability Analysis
A general - purpose approach for assessing the reliability of a nonlinear mechanical system under stochastic conditions was presented in (Faravelli, 1991). It combines the skeleton of...
Stochastic Dynamics of Hysteretic Systems
A frequency domain method is discussed in order to evaluate the second order statistical response of nonlinear hysteretic structures. Both shear type systems and lumped mass frames involving...
Structural Reliability of Seismic Isolation System
Seismic reliability analysis of isolated structure is conducted. In this study focused on are bearing capacity of isolation layer considering strength randomness of isolation bearings...
A Coordinate Reduction Technique With Mass Correction for Dynamic Analysis of Structural Systems
A more accurate technique which can be applied for reducing the order of system matrices when employing the finite element method (FEM) is presented. Unlike traditional reduction techniques,...
Controlled Braking on Uneven Roads
The braking process of a passenger car may be influenced by a large number of variables relating to driver, vehicle, brake system, tire-road interaction and ambient conditions. Because...
A Selective MC Simulation Technique for Nonlinear Structural Reliability Assessment
A selective Monte Carlo simulation (MCS) procedure for the evaluation of the reliability of nonlinear structures subjected to dynamic random loading is presented. The proposed 'double...
Reliability-Based Specification for Engineered Wood Construction
A three-year, industry-sponsored effort has resulted in the development of a reliability-based, load and resistance factor design (LRFD) Specification for wood construction. Improvements...
Load Duration and System Effects in LRFD for Wood Construction
The wood industry is developing a Load and Resistance Factor Design (LRFD) speciification for wood construction using probabilistic concepts. An analysis based on statistical models for...
