Location and Development of Safety Projects
Projects to be considered for inclusion in the Highway Safety Improvement Program (HSIP) must be part of a prioritized listing in which each project is based on accident experience or...

Evaluation?A Key to Safer Design Standards
Public highways are designed and constructed in accordance with established standards which have been developed over the years as a result of research studies or developed by committees...

Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...

The Asbestos Impasse
Removing asbestos from the nation's buildings is a major task . Consulting engineers can play an important part in the process, locating and quantifying the carcinogenic material,...

U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...

A Critical Look at Building Instrumentation in Earthquake Engineering
This paper discusses different issues and requirements existing in the area of building instrumentation. Strategies and types of equipment currently being used by the United States Geological...

Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...

Refinements in Pseudo-Dynamic Test Procedures
One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation...

Use of Vibration Tests to Determine Lateral Load Paths in Medium Rise Buildings
A structural system identification procedure is described in which an initial analytical model of a building is modified until it predicts accurately the mode shapes and natural frequencies...

Seismic Behavior of Long-Span Cable-Stayed Bridges
Special features of the earthquake-response analysis of cable-stayed bridges, subjected to multiple-support excitation, are presented including a basis for calculation of seismic forces...

Seismic Response Analysis of Two Major Bridge Structures
The seismic response analyses of two major bridge structures have been conducted. In these two bridges, portions of the piles are either submerged in the water or free-standing within...

Performance of Existing Buildings: Results of Benchmark Structure Analyses Performed in U.S.-Japan Workshops
In response to the need for better understanding of current safety evaluation methodologies, three U. S. -Japan workshops have been conducted on the evaluation of the performance of existing...

Strengthening of a Multi-Story Building with Deflection Constraints
Occasionally the existing structural or nonstructural systems of a building being strengthened require the imposition of deflection constraints or limits in order to avoid an undesirable...

Regional Risk Assessment of Existing Buildings
This paper describes current research underway at Stanford University designed to develop a methodology for determining high risk buildings in a region. The work involves developing a...

On Reliability-Based Structural Optimization for Earthquakes
Previous studies of reliability-based structural optimization have been extended in order to investigate the applicability of the linear statistical model in cases where random parameters...

Seismic Restraint of Hazardous Process Piping
The lack of appropriate guidelines for the design and installation of hazardous process piping in industrial facilities has created a potentially dangerous situation. Process piping carrying...

Three Phase Design for Wind Loads on Structures
The successful design of a structure requires three phases of work. These phases are: conceptual design, design development and design verification. The conceptual design is undertaken...

Wind Loads and Building Response Predictions Using Force Balance Techniques
The use of force balance techniques to measure mean and dynamic wind loads on models of buildings and structures is discussed. Advantages of using force balance techniques over estimating...

Building Identification: Needs and Means
The need to conduct 'system identification' of existing buildings by nondestructive testing is discussed. A recommended flow-chart is exemplified. Existing dynamic...

Slab Participation in Frames under Lateral Loads
A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested...
