Interactive Analysis and Design Program for Girder Bridges
An interactive microcomputer program for the analysis, design, and rating of girder bridges is presented. The program, GBRIDGE, is user-friendly, menu-driven, and developed in modular...
Interactive Computer Graphic Seismic Design of Frames
An interactive computer graphics approach for earthquake resistant design of two and three-dimensional steel frames is presented. Analysis and design are possible from code-related equivalent...
Integrated Design of Concrete Flat Plate Structures
An integrated structural design and drafting system for concrete flat plate floor systems is described. This system provides at a single computer workstation the tools necessary to layout...
How To Design Highway Retaining Walls?A Practical Application of CADD
The recent work developed at the University of Missouri-Rolla (UMR) including optimization algorithms and two computer programs, ODSEWS-2D-II and ODRESB-3D are discussed. Several numerical...
Analysis and Optimum Design of Nondeterministic Structures under Random Loads
The importance of analyzing and designing structural systems by using a reliability-based approach is emphasized, including system safety requirements with regard to both serviceability...
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...
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...
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....
An Historical Perspective of Failures of Civil Engineering Works
The blight of failures has smitten civil engineering works since ancient times. An examination of historic cases reveals relationships to contemporary cases that are useful in guiding...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
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...
U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...
Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...
Refinements in Pseudo-Dynamic Test Procedures
One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation...
Performance of Existing Buildings: Results of Benchmark Structure Analyses Performed in U.S.-Japan Workshops
In response to the need for better understanding of current safety evaluation methodologies, three U. S. -Japan workshops have been conducted on the evaluation of the performance of existing...
Three Phase Design for Wind Loads on Structures
The successful design of a structure requires three phases of work. These phases are: conceptual design, design development and design verification. The conceptual design is undertaken...
Slab Participation in Frames under Lateral Loads
A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested...
Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...
Settlement of Light Buildings on Loose Sand
This paper reviews several cases of settlement of lightly loaded structures supported on granular soils. The concept of settlement ratio is presented. Measurements indicate that the settlement...
