Field Observation of Aerodynamic Responses of a PC Cable-Stayed Bridge During Its Erection
Recordings were made of the response of a PC cable-stayed bridge during erection and the wind velocity at erection site. These recordings were analyzed to provide estimates of the characteristics...
Safety Evaluation and Verification by Field Testing of Concrete Bridges
This paper describes a method of safety evaluation of concrete bridges in service and the verification of the evaluated results by field tests. The field tests to evaluate structural safety...
Inelastic Earthquake-Resistant Design of Bridges?Application to Concrete Cable-Stayed Bridges
Various methods of earthquake-resistant design of bridges use in both the U.S. and Japan are summarized and reviewed. Among them, principles of approximate and rigorous inelastic earthquake...
Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...
On the Analysis of Viscoelastic Plane Frames
Since its foundation on 1986 the Computational Mechanics Laboratory at the Polytechnic School of Sao Paulo has often been asked for non-linear stability analysis of wood and concrete structures....
Development of Skewed Element for the Concrete Pavements
In the recent years, highway engineers introduced skewed joints in the concrete pavement with a 4 foot to 5 foot skew on a 24 foot width pavement, which results in only one wheel crossing...
In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...
Nonlinear Finite Element Analysis of Experiments on Two-Story Reinforced Masonry Shear Walls
Nonlinear, static finite element analyses are being used for correlation with experiments conducted on one-story reinforced masonry shear walls, and for the prediction of and correlation...
Durability Design for Concrete Bridge Structures
The concept of durability design for concrete structures including bridge structures is proposed on the basis of comprehensive evaluation of materials, design details and construction...
The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...
Experimental Evaluation of Performance of Earthquake Restrainers in Box Girder Bridges
Type C-1 restrainers were used in most of the concrete T- and box girder bridges which have been retrofit. Type C-1 restrainers consist of 7-3/4 in. diam. galvanized cables, bearing plates,...
Vertical Response Data from the Dominion Road Bridge Test
In January and February of 1985, two bridges were tested in New Zealand using simulated earthquake loads. The objective was to determine the in-situ seismic response of two reinforced...
Bond and Dowel Action of a Main Bar in a RC Beam
The bond and dowel action are analytically treated independently on each other in most cases. The bond behavior may be, however, much affected by the dowel action in structural members....
Friction-Dampers for Economic Seismic Design
A novel structural system, which combines the strength and stiffness of a braced frame and energy dissipation capacity of the friction-dampers, has been used in the design of a reinforced...
System Identification of Meloland Road Overcrossing
The Meloland Road Overcrossing (MRO) is a two-span reinforced concrete bridge structure located east of El Centro, California, 0.3 mi from the Imperial Fault. The Imperial Valley Earthquake...
Seismic Evaluation of a Tall Reinforced Concrete Frame Building
Accelerations at basement, fifth and tenth floor levels of a reinforced concrete apartment building were recorded during the October 1st, 1987 Whittier-Narrows earthquake. These accelerations...
Architectural Configurations in Vina del Mar
This paper identifies the architectural characteristics of 121 reinforced concrete buildings in Vina del Mar. These characteristics are related to the damage statistics for the building...
Hydrodynamic Interaction Effects in Earthquake Response of Arch Dams
With the aid of earthquake response results it is demonstrated that the following hydrodynamic effects should be considered in the analysis of the earthquake response of concrete arch...
Hydrodynamic Isolation of Concrete Dams
The feasibility of reducing hydrodynamic effects in the earthquake response of concrete dams by anchoring gas-filled balloons or injecting bubbles in the water is investigated. Significant...
Seismic Evaluation of PG&E Concrete Dams
Seismic evaluation of PG&E concrete dams is an ongoing process. The seismic environment for the dams changes over time because more historical earthquake data is obtained, faults...
