A program has been created in an attempt to utilize the benefits of the microcomputer in assisting the learning process without invoking the attendance 'black-box'...
Finite Element Analysis of R/C Frames and Frame-Wall Systems
A finite element program has been developed for the analysis of reinforced concrete two-dimensional structures. The element library of the program includes, in addition to standard beam...
Nonlinear Analysis of RC Panels Under In-Plane Loading
A new concrete material model based on a modified Mohr-Coulomb criterion is proposed for the nonlinear analysis of reinforced concrete panels. Emphases are made on the softening behavior...
Finite Element Analysis of Punching Shear Strength of Reinforced Concrete Structures
The analysis of reinforced concrete structures using up-to-date computer graphic capabilities is presented. A wide range of linear and nonlinear problems are the subject of this investigation....
Finite Element Software on a Multiprocessor
The continuing implementation and testing of finite element software on the Butterfly Parallel Processor is discussed. The Butterfly computer is a general purpose, shared memory machine...
Accuracy Control of Finite Element Analysis of Articulated Structures
An examination of the properties of two-node element models leads to data establishing the acceptable choices in discretization to insure the accuracy of finite element analysis of articulated...
Reflections on the Impact of Computer Science on Engineering
Over the past several decades, the use of computers in engineering has grown significantly. Over this same time period, work in the relatively new discipline of Computer Science has impacted...
Rebuilding Mexico City
After the September 19, 1985 earthquake in Mexico City, officials had to cope with a massive volunteer effort to inspect damaged and destroyed structures. Over a thousand engineers, contractors,...
Tiedback Walls Untie Intersection
The intersection of Gallows Rd. and Arlington Blvd. in Virginia's Fairfax County required separation. Tiedback retaining walls, which required only 18 in. instead of the 18-22...
Glen Canyon Dam's Quick Fix
When the spiullways at Glen Canyon Dam were severely damaged from unexpected flooding in 1983, the Bureau of Reclamation had just 10 months to repair the tunnel spillway lining and build...
Can Your Design Be Built?
A constructibility review takes place in the concept stage, preferably before the project design is completed. The reviewers usually are contractors or project engineers who have a great...
Water and Wastewater, Time to Automate?
Water and wastewater engineers have been slow to adopt a full circle systems approach to automated monitoring and control. Such a technical tactic for controlling water and wastewater...
Construction Company Builds a Computer System
The case history of the computerization of a construction company is presented. The report reviews the stages that the company went through from manual operations for bookkeeping, estimating,...
Scenic Squeeze
Constructing a four-lane dual highway through the 12 miles of Colorado's Glenwood Canyon involves several engineering innovations: cantilevered roadways, unusual retaining...
Turnaround in Houston
Simply implementing the suggestions of the workers building a 14-story garage in Houston, turned a disaster in the making into a project ahead of schedule and under budget. The work force...
Transportation Liability and Risk Management
Risk management programs provide an excellent response to the increased exposure of all transportation agencies to tort liability claims. While some actions and responses require resources...
Tort Liability in the Pennsylvania Department of Transportation
During the past decade many have questioned the propriety of the doctrine of sovereign immunity; numerous legal challenges and legislative changes have eroded the doctrine in most states....
Risk Management to Reduce Highway Tort Liability
This paper identifies common risk management techniques and processes. A brief review of tort law is presented along with the specific characteristics of a highway related negligence suit....
Economic Analysis of Highway Safety Projects
The most commonly used economic analysis for highway safety projects is the cost-benefit ratio. While this is a valid analytical tool, it must be used correctly to produce valid results....
