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...

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...

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...

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...

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...

Transitioning End Terminal A TRENDtm for the Future
The highway engineer frequently starts from a position where an identified highway element is causing serious injuries or fatalities to motorists on the nation's highways....

Rowes Wharf: A Case Study in Substructure Innovation
Rowes Wharf is a project with many unique features. This paper has attempted to briefly review just one of these features - Up/Down construction. The willingness of the development team...

Innovative Solutions to the Challenges of Heavy Civil Projects
Each heavy construction project presents unique conditions and challenges. For large projects, the work scope may justify an extensive engineering analysis and significant investments...

Demands for Innovation in Power Construction
This paper identifies some specific demands for innovation on power projects, reviews the alternatives considered to meet project objectives, and describes the resulting innovations. Examples...

Attaching Steel Members to Reinforced Concrete Elements
A variety of structural systems have been devised to strengthen existing buildings for improved seismic resistance. Strengthening methods currently in use for reinforced concrete structures...

Design of an Expert System for the Rating of Highway Bridges
A microcomputer-based expert system used to determine the effects of vehicles and overloaded vehicles on simple span bridges with reinforced concrete deck and prestressed concrete I-beams...

RC Structures Under Severe Loads?An Expert System Approach
The authors propose the application of expert systems to the post-test assessment of specific structural systems. In the study reported, an existing expert system shell was employed and...

Applications of Automated Interpretation to Sensor Data
This paper focuses on potential applications of the AISD. (A knowledge-based concept for automating the interpretation of sensor data) concept in civil engineering. A number of potential...

Traffic Barriers: A Second Chance
More motorists are killed each year after striking traffic barriers than any other fixed object except utility poles and trees. These deaths occur primarily because the guardrail or bridge...

Pseudo-Dynamic Testing of Structural Components
The pseudo-dynamic testing procedure is a simultaneous simulation and control process in which inertia and damping properties are simulated and flexibility properties are acquired from...

Nonlinear Behavior of Precast Concrete Shear Walls under Simulated Earthquake Loading
This paper presents experimental and analytical results on precast concrete shear walls under earthquake loading. It was observed in both small scale models tested and the computer analysis...
