Seismic Vulnerability Evaluation in Japan
The state of the art in Japan is reviewed on the evaluation of the seismic capacity of existing low- to mid-rise reinforced concrete buildings, taking into account the different resistance...

Overview of Published Documents for the Evaluation of Existing Buildings
Presently, the most common procedure used by engineers to evaluate existing buildings is probably a code approach that was developed for the design of new construction. Many engineering...

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 Vulnerability and Upgrading of Buildings Geotechnical-Geological Aspects
The effects of local soil conditions on the characteristics of earthquake motions (soil amplification) and on the dynamic response of structures for a given foundation type (soil structure...

Effects of Semi-Rigid Connections and P-? Forces on the Optimum Design of Seismic Steel Frames
By utilizing methods of optimality critera and constraint gradients, the minimum weight design of semi-rigid planar steel frames subjected to static and seismic excitations is presented...

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...

Retrofitting Existing Seismically Hazardous Buildings
This paper presents a brief overview of the types of problems encountered in retrofitting of existing seismically hazardous buildings. Included is a description of the various types of...

Seismic Strengthening of a Historic Unreinforced Masonry Building
The building involved is a four-story unreinforced masonry structure. Considerations related to development of design criteria are presented along with retrofitting strategies. The building...

Study of the Seismic Behavior of Retrofitted Reinforced Concrete Buildings
Over ten years experimental research in Japan on the seismic behavior of retrofitted reinforced concrete buildings is reviewed. Emphasis is put on the improved strength and/or ductility...

Seismic Repair, Restoration and/or Upgrading of Existing Buildings
The ultimate goal of this paper is to discuss the selection of the most efficient (optimal) strategies and techniques for upgrading an existing building. To achieve this goal, it was considered...

The New 1988 SEAOC Blue Book and 1988 UBC Overview of Lateral Force Section
This paper presents an overview of the lateral force section of the new seismic design provisions of the 1988 edition of the Uniform Building Code (ICBO, 1988), and the 1988 Blue Book...

The 1988 UBC Seismic Provisions for Steel Structures?An Overview
This paper will give the reader an introduction to the seismic design provisions for steel structures in the 1988 Uniform Building Code. Chapter 27 in the 1988 UBC now contains over ten...

Concrete Structures?1988 UBC Seismic Provisions
This paper discusses the special requirements in the 1988 edition of the Uniform Building Code concerning reinforced concrete structures resisting forces induced by earthquakes. The provisions...

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...

1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...

Recent Developments in Testing Base Isolation Systems
One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of...
