Safety Performance Evaluation of 21st Century Appurtenances
A great deal has occurred in the highway safety field in the last 15 years: there have been societal changes which have altered the character of the vehicle fleet; there have been technological...
Future Driver and Vehicle Characteristics and Their Influence on Highway Design for Safety
Both driver and vehicle characteristics are changing, and these characteristics will continue to change into the 21st century. The purpose of this paper is to identify the major changes...
Plugging the Public Sector Brain Drain
For years, many agencies have been able to hire and retain highly-educated, highly-skilled work forces, even though their wages, incentives and working conditions have not been fully competitive...
Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...
The Economic factors of Ground Water Recharge Projects
As a result of the Water Conservation and Water Quality Bond Law of 1986, the State of California is now providing low interest loans to local water agencies to finance ground water recharge...
Water Transfers - The Goose that Lays the Golden Eggs
Water transfers occur naturally due to gravity and artificially due to man. Transfers by man are made in order to increase the value of the resulting product per quantity of water used....
Positioning for Success
A model, called the SuperPositioning Model, for successful management of engineering design firms is discussed which allows firms to be categorized within a matrix bounded by two primary...
Effects of the 1985 Earthquake in Lazaro Cardenas, Mich.
An account is presented of a geotechnical survey made shortly after the major earthquake of September 19, 1985 (magnitude 8. 1) at the industrial port of Lazaro Cardenas in the state of...
Seismic Design Criteria for Foundations on Control Piles
Control piles have been widely used in Mexico City for underpinning buildings with excessive settlements caused by the consolidation of the soft clay deposits, and as a foundation solution...
Evaluation of Performance of Concrete Buildings Damaged by the September 19, 1985 Mexico Earthquake
As a part of a general evaluation of the structural behavior of buildings during the 1985 earthquake in Mexico City, a detailed study of 8 damaged concrete buildings has been performed....
Behavior of Reinforced Concrete Framing Systems
On September 19, 1985, Mexico City was hit by what is believed to have been the most damaging earthquake in its recorded history. In this report, a ground motion recorded in the severely...
Summary of the Effects of the 1985 Mexico Earthquake to Power and Industrial Facilities
A major industrial area and two power plants are near the epicenter of the Magnitude 8. 1 Mexico Earthquake of September 19, 1985. All investigated facilities are modern, generally well...
Damage Assessment and Seismic Behaviour of Steel Buildings in Mexico City
Preliminary reports on the September 1985 earthquakes indicated 10 steel buildings collapsed and 2 more severely damaged. The total number of buildings found either collapsed or severely...
Emergency Regulations and the New Building Code
The 1942 Federal District Building Code was crude and overoptimistic. The 1957 earthquake prompted the drafting of emergency regulations, modern and more realistic. They evolved into the...
Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...
The Problem with Public Works
This article discusses the reasons that public projects take longer to complete than private projects do. Unencumbered by the laws, regulations and political conflicts that slow public...
Taking Water to Market
If the West is to enjoy continued population growth and economic development, huge volumes of water must be switched from farming to municipal uses. A free market in water will encourage...
Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...
Uplift Capacity of Model Group Anchors in Sand
Small-scale laboratory experimental results for the ultimate uplift capacity of shallow horizontal circular single and group anchors embedded in sand have been presented. The experimental...
