Size Effect in Concrete Structures and Influence of Loading Rate
The size effect law models the influence of the dimensions of the structure or specimen on the failure stress. This model can be used to quantify the brittleness of failure, and determine...

Accurate Computation of Freezing Index
'Freezing index' (cumulative degree-days below freezing) is used for predicting frost penetration depths and modelling pavement performance. Contour maps which illustrate geographic trends...

Theoretical Prediction of Temperature Distributions in Airfield Runway Pavements Due to Aircraft Operation
The determination of this transient temperature distribution is important in predicting the thermal effects on pavements due to aircraft operation. In this research, heat exchange at the...

Anomalous Structural Size Effect in Cohesive Materials Like Concrete
This contribution analyses on theoretical grounds the size effect trends in special cases where - unlike most experimental situations in fracture research - the specimen is not precracked...

Seismic Surgery
The authors describe the installation of seismic isolators in the columns of an eight-story concrete building in Seal Beach, Calif., which serves as Information Systems Center for Rockwell...

The Demonstration Project on Seismic Loss Estimation for Water Systems
This year a monograph is being produced that summarizes results of a four-year project by the Technical Council on Lifeline Earthquake Engineering (TCLEE) of ASCE in order to demonstrate...

Effects of Uncertainties in Component Fragilities on Lifeline Seismic Risk Analysis
Accurate calculation of the seismic risk for lifelines requires modeling the system as a function of its components, and requires accurate modeling of two engineering factors: (1) the...

Seismic Risk Considerations for Transportation Systems
During the recent Loma Prieta Earthquake, major damage to certain key transportation elements greatly affected operations of major transportation systems within the San Francisco Bay Area....

Recent Lifeline Seismic Risk Studies
This monograph is a collection of four papers presented at the 1990 Annual Civil Engineering Convention and Exposition in San Francisco, California. The papers summarize seismic loss and...

Orchestral Maneuvers
Symphony Towers is an H-shaped superstructure that straddles Symphony Hall in downtown San Diego. The $143 million project is a 34-story office building to the south of the hall and a...

Assessment of Conductors
This paper deals with the mechanical integrity of conductors after several years in service and discusses current innovative conductor designs which benefit the structural designer working...

Optimal Location of Active Controllers Subjected to Seismic Excitation
In the application of structural control to seismic structures certain locations are advantageous for placement of the actuators. These locations reduce the structure's response...

An Integrated Knowledge System of Seismic Vulnerability and Risk for Engineered Facilities
This paper describes an integrated knowledge system for the assessment of the seismic vulnerability and risk of engineered facilities. The system integrates knowledge from many fields...

Review of Composite Analysis Methods for High Temperature Applications
This paper addresses a number of unique problems encountered in the stress analysis of high temperature composite materials. The materials used as structures subjected to temperatures...

Effect of Temperature on the Load-Carrying Capacity of Fiber Glass Reinforced Plastic Beams
This paper describes an experimental investigation into the behavior of two T shaped beams made of fiber glass reinforcement and polyester or vinylester binders. Tests were performed at...

The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...

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...

Forced Vibration of Sliding Base Structural Systems
An analytical and experimental study of the effect of a horizontal sliding plane on the dynamic response of a single-story structure subjected to harmonic motion is presented. There is...
