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...
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...
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...
Strong-Motion Records from Buildings
Since the establishment of the California Strong Motion Instrumentation Program in 1972, over 90 buildings have been instrumented extensively to measure their response during earthquakes....
Some Significant Records from Instrumented Structures in California?USGS Program
The main objective in seismic instrumentation of structures is to facilitate response studies that lead to improved understanding of the dynamic behavior and the potential for damage to...
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...
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...
Detection of Seismic Structural Damage
Damage analysis models based on equivalent modal parameters are used to identify the serviceability limit state for structures subjected to earthquake loads. A model for the analysis of...
Seismic Performance of Existing Building in New York City
Strength-based damage indices depending on structural shear capacity and earthquake intensity are used to predict the seismic performance of existing buildings in New York City. Nonlinear...
Seismic Evaluation of Buildings in the Eastern and Central United States
The Applied Technology Council (ATC) has developed and published a methodology, ATC-14, for evaluating specific buildings that is tailored for use by practicing structural engineers. ATC-14...
Seismic Isolation of the USC University Hospital
This paper provides an overview of the various structural engineering tasks that are associated with the implementation of the design of a seismically isolated structure. The project is...
Seismic Isolation for the Los Angeles County Fire Command and Control Facility
The use of seismic isolation is becoming an increasingly important consideration in improving the earthquake lifelines of a community. This paper identifies the major problems encountered...
Seismic Isolation of a Flight Simulator Manufacturing Facility
The corporate headquarters of Evans & Sutherland is located in the University of Utah Research Park which is in Salt Lake City, Utah. A major fault runs through Salt Lake City...
The Application of Seismic Isolation to Bridges
Unlike a building application the primary intent in a bridge is to protect the structure below the plane of isolation - the superstructure being relatively rigid to in-plane loads and...
Seismic Strengthening of a Tall Masonry Building
The design of a strengthening system for a tall building is proposed using ductile reinforced masonry shear walls. This innovative design concept produced a system that controlled the...
Seismic Safety Regulation of Existing Structures
Establishment of standards for seismic strengthening of existing buildings has been difficult since full compliance with current codes is generally too expensive. A general consensus has...
Historic Background of Seismic Construction in San Francisco
A seismic design and construction tradition has developed in California because of the unique experience with local earthquakes. After the 1906 earthquake and fire, building performance...
Recent Developments in Isolation Hardware
Most isolation systems have at least two physical components: one specifically intended to add flexibility and the other to control the resulting deflections. However, other elements may...
Site Characterization of Yorktown Formation for New Accelerator
The design of a new 1700-m long continuous-wave electron beam accelerator facility (CEBAF) in Newport News, Virginia demanded an extensive geotechnical exploration program be conducted...
Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...
