RISMinimum Cost Prestressed Concrete Beam Design
Publisher: American Society of Civil Engineers
Abstract: An integer programming formulation for the minimum cost design of precast, prestressed concrete simply supported beams is developed. The cross section and gridwork within which strands must be placed are assumed given, and ...
Bearing Capacity of Breakwater Subjected to Tsunami-Induced Scour
Publisher: American Society of Civil Engineers
Abstract: Physical models have suggested a large reduction in bearing capacity of simple foundations due to overtopping tsunami scour. We use the results of these tests to create scoured foundation geometries for simple breakwater-type ...
Skewed Discretely Connected Multi‐Beam Bridges
Publisher: American Society of Civil Engineers
Abstract: Recent multi‐beam bridge designs have been developed around standard prestressed, precast double‐tee sections to combat the high cost of this particular type of bridge design. Although several methods of multi‐beam bridge ...
Optimum Design of Spread Mooring Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design of a spread mooring system of given pattern with single segment lines on a flat seafloor is formulated as a mathematical programming (optimization) problem. Design variables are the ...
Comparison of Burning Rates in a Natural-Gas-Fueled Spark Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A series of tests was conducted on a Toyota, four-cylinder, spark ignition engine which was modified to run on either gasoline or natural gas. The aim of the experiment was to investigate ...
Subsurface Characterization with Solid Models
Publisher: American Society of Civil Engineers
Abstract: Three‐dimensional computer models of construction sites and subsurface stratigraphy are useful for visualization, analysis, and design in geotechnical engineering. A useful technique for creating such models is the geometric ...
Algorithm for Smoothing Triangulated Surfaces
Publisher: American Society of Civil Engineers
Abstract: Surfaces defined by linearly interpolating a two‐dimensional triangulation of a set of scattered data points are frequently used to describe geometry in computer applications. The linear nature of such surfaces simplifies ...
Safety Treatments at Isolated High-Speed Signalized Intersections: Synthesis
Publisher: American Society of Civil Engineers
Abstract: High-speed intersections pose a safety and operational challenge. Currently, no specific guidance for treating high-speed intersections exists, particularly in the case of intersections with substantial truck traffic. To ...
Discussion: “An Examination of a Proposed Method for Evaluating Nonlinear Effects in Fracture Assessment” (Adams, N. J. I., and Munro, H. G., 1976, ASME J. Pressure Vessel Technol., 98, pp. 40–45)

Mesh Generation for Estuarine Flow Modeling
Publisher: American Society of Civil Engineers
Abstract: A finite element computer modeling system called TABS‐2 has been developed by the U.S. Army Engineer Waterways Experiment Station, Vicksburg, Mississippi. TABS‐2 has been used to model shallow water flow in estuaries. ...
