In the past several years, considerable research effort has been devoted by the Electric Power Research Institute and the U.S. Nuclear Regulatory Commission to the behavior of reactor...
Strength Evaluation of Existing Reinforced Concrete Structures
The load test as described in ACI 318-83 Chapter 20, entitled 'Strength Evaluation of Existing Structures,' was conducted at 60%, 80%, and 100% of the calculated...
Mitigation of Wind-Induced Vibration of Tall Buildings
This paper summarizes a detailed study of the sensitivity of building acceleration to changes in structural stiffness, mass and damping and to the eccentricities in the centers of stiffness...
Analysis and the Design of Multi-Layer Viscoelastic (V.E.) Dampers for Tall Structures
Vibrational motion of tall buildings can be damped by employment of viscoelastic passive dampers in the structure. The type of dampers selected depend on locations where relative displacements,...
Optimum RC Member Design With Discrete Sections
This paper concentrates on the development of simplified yet effective algorithm for optimum reinforced concrete (RC) member design. After constructing the data base of predetermined reinforced...
Flexural Strength of Ultra-High Strength Concrete Members
Various proposals have been made for the pridiction of strength of high strength concrete sections. One of the most important parts of any strength computation procedure is the assumption...
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...
