Seismic Assessment and Renovation Study for Highway Bridges
This paper is concerned with hazards mitigation on highway bridges due to earthquake ground motions. Damage to transportation systems may occur if the acting faults of May-Shan and Tsu-Kou...

Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...

Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....

Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...

Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...

Reliability-Based Expert Systems for Optimal Maintenance of Concrete Bridges
In this paper ongoing research in the CEC supported BRITE/EURAM project P3091 is presented. In the project reliability based expert systems for inspection and maintenance of corroded reinforced...

Damage Estimation of Existing Bridge Structures
During recent earthquakes, severe damage have been reported in many bridge structures. Regardless of many damaged structures, methods to identify damage of structures are still limited...

Nonlinear Dynamic Analysis of Single Point Moored Buoy Under Wave and Current Loadings
In this study, a single point moored spherical buoy under wave and current loadings is analyzed in the time domain considering time memory effects. Geometric nonlinearity of the mooring...

Recent Successes in Welding Jumbo Shapes
A rather unique structure utilizing jumbo shapes was recently designed and fabricated. The structure was 100% welded according to the specifications for welding jumbo shapes recently developed...

The Effect of Nonlinear Drag PSD on Fatigue of Compliant Offshore Structures
Structural fatigue damage induced by random ocean wave loading on a compliant type of offshore structure is considered. The nonlinear wave force is modeled by the Morison equation and...

Teaching Structural Engineering in Year 2000

Jatiluhur Dam: Problems and Rehabilitation
The Jatiluhur Dam in Indonesia, completed in 1965, is an innovative design consisting of rockfill embankment with a clay core and a vertical cylindrical Intake Spillway. Within the Intake...

Rock Structure in Relation to Concrete Dams on Granite
Granite is often considered to provide an excellent foundation for a concrete dam and a great many dams are thus founded on granitic rocks. Although granitic rocks lack the bedding of...

Risk Assessment: A Tool for Dam Rehabilitation Decisions
A phased approach to the dam rehabilitation decision problem is presented. The approach is based on viewing the newer dam safety evaluation approaches of incremental damage assessment...

Prediction of Embankment Dam Breaching for Hazard Assessment
Downstream hazard assessments for dams require prediction of 1) whether a breach could form, and 2) the hydraulic characteristics of the breach for use in calculations of discharge and...

Risk-Based Methodology for Seismic Rehabilitation of Earth Dams
A methodology for seismic risk analysis of earth dams is described. The procedure utilizes seismological and geotechnical inputs together with the associated uncertainties and provides...

Design Considerations for Raising Existing Dams for Increased Storage
While a number of new dams have been constructed in the United States and other countries in recent years, much of the construction activity related to dams has involved the raising of...
