Pressure Measuring System for Wind Loads
A project to acquire wind and building surface pressure data in the field is continuing at Texas Tech University. A test building of dimensions 30 ? 45 ? 13 ft (9.1 ? 13.7 ? 4.0 m) and...
An Overview of the U.S. Coordinated Program for Masonry Building Research
The U.S. Coordinated Program for Masonry Building Research is a time-phased set of specific research tasks addressing materials, component and system behavior. The objective of the program...
Influence of Nonlinear Models on Dynamic Displacements
This research is a part of an ongoing multi-year program that is sponsored by the National Science Foundation and conducted under the TCCMAR (Technical Coordinating Committee for Masonry...
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...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
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)....
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...
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...
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...
ATC-22: Development of a Handbook for ATC-14
The ATC-22 project is the development of a Handbook for the application of the methodology of ATC-14 for the seismic evaluation of existing buildings. The development of the Handbook itself...
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...
Consequences and Achievement of Supplemental Damping for Improved Seismic Performance
An earthquake resistant design philosophy which relies upon increased stiffness and damping rather than increased strength and ductility has been investigated. The effect of adding supplemental...
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....
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...
Seismic Instrumentation and Its Implication for High-Rise Buildings in Japan
An outline of the present state of the strong earthquake motions observation systems in Japan and an example of the obtained records of an earthquake and its simulation analysis of a high-rise...
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...
Seismic Design of Highrise Building with Mega Frame
The NEC corporation head office building is under construction at Shiba Minato-ku, Tokyo, Japan. This building is a highrise building of steel structure with the height of 180m. The structural...
Structural Considerations in Design and Construction Process of a 25 Story Office Building
This paper introduces an example in which a steel office building of 25 stories above the ground was constructed employing innovative techniques. One of them was the use of precast concrete...
