Dynamic Response Prediction for Earthquake Resistance Design of Bridge Structures
Newly developed nonlinear analysis procedures for assessing the earthquake resistance of bridges have been incorporated into the computer program SEISAB (SEISmic Analysis of Bridges)....
Reliable Displacements from Integrated Quick-Release Accelerograms
A new baseline correction method has been developed which allows accelerograms collected during quick-release tests of full scale structures to be doubly integrated to displacements. The...
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...
Effects of Vertical Motion on the Inelastic Behavior of Highway Bridges
The response of typical highway bridges to the vertical component of earthquake ground motion has a significant effect on their elastic behavior. When vertical motions are considered along...
Rapid Visual Screening of Buildings for Potential Seismic Hazards
A Rapid Screening Procedure (RSP) developed for use nation-wide is based on a 'sidewalk survey' of a building, in which a Data Collection Form is completed by...
Experimental Study on Structural Control for Seismic Loads Using Passive and Active Devices
The feasibility of controlling the responses of structures against seismic loads is investigated through some experiments and numerical analyses for both the passive and active control...
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....
ATC-23: A Survey of California Hospitals for Earthquake Survivability Potential
In September, 1986 the SSC recommended the completion of a survey of existing acute care hospitals as the first step in a program to bring about the upgrading of all pre-1973 hospitals...
ATC 14: A Methodology for the Seismic Evaluation of Existing Buildings
A new method for evaluating the seismic resistance of existing buildings has been developed based on the historic performance of buildings in past major earthquakes. This methodology identifies...
Postearthquake Safety Evaluation of Buildings
Procedures for the safety evaluation of buildings in earthquake damaged areas have been developed. Two evaluation techniques, Rapid Screening and Detailed Inspection, are described. Rapid...
Earthquake Damage Estimates of Conventional and Isolated Structures
The philosophy inherent in current seismic design codes for buildings accepts the premise that there will be both structural and non-structural damage but that life safety will be preserved....
Forced Vibration of Sliding Base Structural Systems
An analytical and experimental study of the effect of a horizontal sliding plane on the dynamic response of a single-story structure subjected to harmonic motion is presented. There is...
Earthquake Resistant Design Using Friction Pendulum Connections
The Friction Pendulum System (FPS) offers a simple approach for increasing a structure's earthquake resistance. The approach uses steel connections which absorb earthquake...
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...
N-Pad?A Three-Dimensional Program for the Analysis of Base-Isolated Structures
N-PAD is a three-dimensional computer program especially written for the analysis of base-isolated structures. The program is designed with the ability to model various types of isolation...
