A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....

Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...

Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...

Model for the Optimal Rehabilitation and Replacement of Water Distribution System Components
The objective of the model presented is to determine the minimum cost solution, given the nonlinear nature of the equations required to describe the cost and the hydraulics of a water...

Reducing Maintenance Costs of Irrigation Systems
Reducing the costs of maintaining an irrigation water delivery system is becoming more important as the financial problems of the irrigators become more critical. The maintenance costs...

Weather Modification Regulation for the Twenty-First Century
Those areas in which weather modification law is being altered to fit the twenty-first century are: 1. De-regulation. Regulation of weather modification through mandating professional...

Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....

Optimum Irrigation Under Saline Conditions
A dynamic production function for cotton is estimated. Optimal irrigation volumes, timing, and qualities are calculated using dynamic programming. Optimal water quantities are sensitive...

Review of the Lake Andes-Wagner Project Sizing
Benefit-cost analyses of the proposed U. S. Bureau of Reclamation Lake Andes-Wagner Project have shown the project to be marginally feasible. In an effort to improve the benefit-cost ratio,...

The Far? Bridge?Long Life at Low Costs
The superstructure of the bridge is a steel structure which proved to be competitive compared to the tendered concrete solution, due to simple and rational design both structurally and...

Optimal Flood Warning and Preparedness Plans
This paper includes a framework for selecting the optimal investment in warning and preparedness activity. The primary factors which might influence the magnitude of cost and damage are...

Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...

Use of the DEB Model in MARTA's Service Planning
The Metropolitan Atlanta Rapid Transit Authority (MARTA) is in the process of expanding bus and rail services. The expansion program requires the preparation of annual and five year system...

Use of a Schedule and Runcut Simulator
The development of a computer program which simulates the transit scheduling and runcutting processes is discussed. The program, called OCRS, was developed for the Multi-Corridor Project...

Running Rucus II on a Microcomputer
Since the preliminary version of the RUCUS II (Run Cutting and Scheduling System) was released by UMTA in 1982, the system has achieved considerable acceptance by transit properties. These...

Seven Myths of Managing Microcomputers
Microcomputer usage in the transportation community has grown so rapidly in recent years that it seems sometimes that we are being overwhelmed, and maybe oversold, by the technology. As...

Sell Your Organization on the Seven C's for Effective Microcomputer Management
Managing microcomputer resources within your organization is not always smooth sailing. This paper will highlight seven attributes which an organization would do well to follow for more...

Procedures for Evaluating TSM Projects
The constraints of limited funding, increasing demand and environmental impact have led to an increase in Transportation Systems Management (TSM) improvements on surface transport systems....

Economic factors of Wave Energy Conversion
The paper provides some insights into the institutional setting in which power marketing is conducted (in the United States). It presents some approaches to economic evaluation that might...

Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....
