Moving Toward a Probability-Based Risk Analysis of the Benefits and Costs of Major Rehabilitation Projects
By the year 2010, 77% of the U.S. Army Corps of Engineer's projects will be over 40 years old. The Corps wants to allocate its scarce rehabilitation funds in a cost-effective manner. To...
A Probabilistic Regional Damage Estimation Model for Earthquake Occurrences
In this paper we present a model for estimating regional earthquake damage. The model utilizes the relational data base management system ORACLE and the geographic information system ARC/INFO...
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...
International Harmonization of Reliability-Based Timber Engineering Design Codes
An overview is presented on reliability-based timber design code activities in various major timber producing and consuming countries. The overview is based on information generated through...
Serviceability Analysis of Wood Beams with Creep
The effect of creep deformations on the serviceability reliability of single, dimension lumber wood beams is examined. A viscoelastic stress-strain relationship is used to model the time-dependent...
Experimental Study of the Transient Temperature Distributions in Concrete
A small scale, preliminary experimental effort to quantify the randomness of the thermal diffusivity of concrete has been undertaken. Two sets of cylinders have been instrumented with...
Fabric Related Probabilistic Model for Granular Materials
A new anisotropic noncoaxial incremental constitutive model for granular materials (Jahedi et al., 1990) was developed, in which a Fabric reconstruction factor '?+',...
An Advanced First-Order Method for System Reliability
This paper proposes an iterative first-order method for accurate estimation of the joint failure region of two nonlinear limit states. Current methods use either a first-order approach...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
A Two-Stage Safety Assessment Methodology for Construction Activities
The control of construction activities requires the evaluation of the condition of the control attributes of interest. In order to develop the required methodology, a model of the construction...
Connecticut's Wellhead Protection Program
Connecticut's Wellhead Protection Program was the first in the country to receive EPA approval and remains one of the strongest programs in the nation. The program is based on comprehensive...
Technology Transfer for Projects in South America
Engineering services were provided for three projects in South America. One project was located in the Pampa Region of Argentina and two others in northern Brazil. The projects were: 1)...
Promoting Private Irrigation Development: The Irrigation Sector Program Experience in Nepal
In 1988, Nepal embarked on development of an Irrigation Sector Program. The key ingredients of the program are direct farmer participation in irrigation development and establishment of...
Holistic Approach to Irrigation Management in Developing Countries
Sound development of irrigation and drainage projects in developing countries is a continuing need to reduce hunger, environmental degradation and excess population growth; and to promote...
Water Management Under Drought Conditions: An Overview of Practices by Non-Federal Entities
This paper provides an overview of water management procedures and practices of non-federal water management agencies under drought conditions. The general components of drought water...
Management of Agricultural Drainage Pollution Considering Regional Cooperation
Increasing awareness of toxic substance discharge from agriculture in the San Joaquin Valley of California has resulted in discharge limits on individual constituents in agricultural drainage....
Importance of the Tropical Rainfall Measuring Mission (TRMM) Satellite to Hydrological Investigations
Rainfall over the global tropics is crucial to the global hydrological cycle and to water resources in most developing countries. Its magnitude and variations are presently poorly known....
Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...
