A Simulation of the Quake-response on the Frame with Large Basement-box under the Earthquake from Deep Soil Layer
This paper treats a study of computing vibratory analysis and its comparison with measurements for the earthquake-responses on an actual 19 storied pure frame-structure with its height...
Linking CAD and Expert Systems for Constructibility Reasoning
This paper describes the prototype expert system COKE (Construction Knowledge Expert) that was recently developed at the Center for Integrated Facility Engineering (CIFE) at Stanford University....
The Use of Numerical Rule Processors in Engineering Calculations
A Numerical Rule Processor uses a declarative approach to the processing of engineering calculations. The rules which link the parameters are set out in a separate rule base and the order...
Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...
Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
User Identified Short-Term and Long-Term Needs for Pavement Management Innovation
A survey involving 300 practicing engineer's from all over the United States and representing 20 other countries was conducted, concerning ideas and opinions of the priority research needed...
Reliability Assessment of Concrete Pavement Sawing
Traditional concrete pavement design sometimes realize on qualitative decision based on experience, with concrete pavement sawing operations representing a specific case in point. presently,...
Infrastructure Repair with Polymer Composite Using Recycled Plastics
Recycled poly(ethylene terephthalate), PET, mainly recovered from plastic beverage bottles, can be used to produce unsaturated polyester resins. Polymer concrete (PC) made with these resins...
Dynamic Study on New Guideway Structure for JR Maglev
This paper presents an introduction of the study for the design and technical development of a newly proposed guideway structure for the superconductive magnetically levitated train system...
Making the Leap
Over the past decade, computers have become as much a part of the engineering field as concrete and steel. But bringing a firm into the information age can be complicated and expensive....
The NOAA Restoration Center: Next Steps
The National Oceanic and Atmospheric Administration (NOAA) Restoration Center (RC) was founded in 1991. Since its inception it has made significant progress along several fronts. Foremost,...
The Present Condition and Future Prospects of the Shonan Nagisa Plan
The central part of Kanagawa prefecture adjoining metropolitan Tokyo, and facing the Sagami bay is called the Shonan area. Since the 1950', the area's mild climate, abundant greenery and...
Vitalization Policy of Local Region by Port Space Utilization
The present paper investigates policies of decayed local regions by port space utilization in Japan and proposes a new frame to manage risks in order to lead them to success. It contains...
Application of Composite Members to Marine Structures in Japan
Composite structures combined steel plates and reinforced concrete with shear connectors have been applied to port and harbor facilities in Japan since the early 1980s.Composite structures...
Manning's n From Experiments with Rainfall-Runoff on Portland Cement Concrete Surfaces
Experiments were conducted under artificial rainfall on Portland cement concrete (PCC) surfaces with variable mean texture depths (MTD) and slopes (S). Rain rates were varied up to 3 in/hr...
Short-Span Bridge Solutions
Large bridges get most of the headlines, but the nation's huge network of small bridges (many with spans of less than 25 ft) may be more in need of replacement. Age, corrosion,...
Velocity Reduction at a Submerged Pipe Outlet
This paper presents the results of a specific model study to reduce the 17.5 m/s (57.3 ft/s) discharge velocity of a submerged circular pipe discharging at floor level into a 30.5 m (100...
Analysis of Cabinet Gorge Dam
After a 1987 inspection of the Cabinet Gorge Dam, Part 12 consultants contracted by Washington Water Power (a private utility based in Spokane, Washington) made several recommendations...
Dam Safety Modifications for Clear Creek Dam Manuscript for ASCE Hydraulics Division 1993 National Conference on Hydraulic Engineering
Clear Creek Dam, an unsafe thin arch dam, was stabilized by constructing a concrete gravity buttress on the downstream face. During the Bureau of Reclamation's (Reclamation) Safety Evaluation...
