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...
Analysis and Design of Prestressed Concrete Spun Poles
A microcomputer package for the analysis and design of prestressed concrete spun poles is described. The package, named PCPAD, consists of six programs each having a specific analysis...
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....
Creep Modelling for Masonry under Plane Strain
A computational procedure based on the principle of superposition to estimate creep strains in composite masonry walls is developed and presented in this paper. This development is based...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
Attached Scientific Computers in Structural Analysis
The design and analysis process is explored in terms of its requirements for user decision-making and interaction. This is presented as a three-phase procedure: (1) the engineer developing...
Equation Solving on a Parallel Computer
The application of computers to the analysis of large structural systems is examined. The analysis procedure is presented as three distinct phases: (1) element formulation, (2) equation...
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...
A Perspective on Engineering Computing
Computing in engineering seems to be evolving very rapidly and yet the data shows that it frequently takes twenty years before a viable concept becomes widely available. Economics is the...
The Mexican Earthquake: A Firsthand Report
The Mexican earthquake of September 19, 1985 was most peculiar, because of the combination of its intensity, regularity, and duration. No other earthquake has had an intensity of IX, at...
Liability: Problem or Crisis?
Engineering firms are being hit with liability insurance rate increases of 30%, 50% or more. Deductibles are being raised and the maximum coverage is being decreased. Some firms cannot...
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...
Spanning Urban Obstacles
Extension of Pittsburgh's Crosstown Expressway is a � mile portion of a massive $500 million urban highway now under construction. The extension is a complex of five roadways...
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...
Effective Pedestrian Safety Programs
Pedestrian fatalities account for 16 percent of all highway-related deaths and about 129,000 pedestrians are involved in accidents each year. Analyses of pedestrian accident data and determining...
Safety Impacts of Installing Pedestrian Crosswalks
At-grade pedestrian crossovers (PXO's) have been installed at about 700 locations in Metropolitan Toronto to assist pedestrians in crossing busy streets at minimal delay to...
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....
Evaluation of Safety Alternatives by Benefit/Cost Analysis
There is an increasing awareness of the need to use limited highway safety funds on projects that offer the greatest benefits. This paper describes the development and application of a...
Some Questions on the Accuracy of Safety Effectiveness Evaluations
The generally positive benefits of safety improvements, and, in particular, upgraded traffic control devices, are well-established. More difficult is the explicit rank-ordering of traffic...
Shoulder Rumble Strips at Narrow Bridges
The highways in the United States have thousands of minimum design narrow bridges. Replacement of these bridges with current state of the art designs is not cost effective nor feasible...
