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...

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...

Amelioration of Stirrup and Compression Reinforcement on the Ductility of Reinforced High-Strength Concrete Beam
18 rectangular high strength concrete beams were tested to investigate their ductile behavior. The results show that it will be more advantageous, for ductility, to choose the compressive...

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...

Development of Design Requirements for Seismically Isolated Structures
This paper provides background and describes on-going work by the Structural Engineers Association of California (SEAOC) to develop design requirements for seismically isolated structures....

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...

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 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...

1988 Provisions for Masonry Design
The 1988 Uniform Building Code has seen a significant change in the seismic design requirements, Chapter 23, for the design of structures subjected to earthquake loads. This paper discusses...

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...

Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....

Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
