Probabilistic and Reliability Analysis of Asphalt Concrete Airfield Pavements
A procedure was developed to analyze layered elastic asphaltic concrete airfield pavement systems in terms of probability and reliability. Rosenblueth method is used to estimate the expected...
On the CICIND Code
The CICIND Model Code for Concrete Chimneys was created by CICIND, an international technical association which has as one of its main aims the creation of harmonized internationally accepted...
Probabilistic Evaluation of Load Factors for Steel Rigid-Frame Piers on Urban Expressway Network
A procedure is proposed for calculating the optimal load factors for steel rigid-frame piers using the extended level 2 reliability method. Twelve typical types of pier structures are...
Ultimate Limit State Design for Earthquake Resistant Steel Frames
This paper describes a basic methodology to assess the reliability of steel framed structures subjected to ultimate earthquakes. After a discussion on past damage criteria, a modified...
Code-Implied Structural Safety for Earthquake Loading
A method is described for calculating the probability of failure of reinforced concrete frame structures due to earthquake loading, for use in code calibration exercises. The failure criterion...
Reliability Bases for Codes for Design of Reinforced Concrete Structures
The American Concrete Institute Standard 318, Building Code Requirements for Reinforced Concrete, has permitted the design of reinforced concrete structures in accordance with limit state...
Reliability Models of the Mohr Failure Criterion for Mass Concrete
Failure in biaxially stressed concrete is here modelled by the Mohr criterion. The reliability of a stress state is evaluated in terms of 2 load variables and 1 or 2 strength variables....
Reliability Analysis of Reinforced Concrete Structures for Serviceability Limit States
Some problems of reliability analysis of reinforced concrete structures in serviceability limit states are discussed, and two reliability analysis methods for serviceability limit states...
Statistical Properties of Prestressed Concrete Beams in Shear
Monte Carlo simulations were performed on prestressed concrete rectangular and tee-section beams in shear produced by a single concentrated load at mid span. The truss analogy model was...
Strategies for Bridge Inspection Using Probabilistic Models
This paper describes the application of probability analyses in planning an inspection program for highway bridges. When damage in the form of fracture and cracking is the major concern,...
Reliability Assessment and Reliability-Based Rating of Existing Road Bridges
A practical reliability model for the safety assessment and rating of existing R.C. bridges are developed by explicitly incorporating the degree of deterioration and damages based on available...
Vibration Tests and Damage Detection of P/C Bridges
A three-span countryside P/C bridge has been found to have excessive deflections in two of the three spans. It is reported that the prestresses in tendons of two girders of different spans...
Mode Truncation Effects on Flexible Space Structures
This paper deals with the problem of active vibration control of flexible space structures. The main difficulty associated with this problem is that the structure has infinite vibration...
The Prefab Tunnel
Jacking a prefabricated concrete arch through a railroad embankment to provide a new access ramp to the Don Valley Parkway in Toronto was done for the first time in North America. In September...
Tales From Milwaukee's Underground
Written from RETC papers and interviews, this article is a status update on the Milwaukee Metropolitan Sewerage District's $2.1 billion Water Pollution Abatement program,...
Prestressed Concrete Pipe Field Test
Strain changes in the prestressing wires and deflections of a 2130-mm-diameter precast (embedded cylinder), prestressed concrete pipe were measured during earth backfilling operations....
Buried Structural Capacity of Insituform?
In July 1988, a test was conducted at Utah State University to determine the structural support that can be provided to a failing rigid pipe system through the use of the Insituform process....
Investigation & Rehabilitation of Seattle's Tolt Pipeline
Seattle Water Department's Tolt Pipeline brings water 24 miles from storage in the Cascade Mountains into city and suburban distribution systems. Twenty-three miles of this...
In-Situ Evaluation of 30-In. (762-mm) Diameter Prestressed Concrete Lined-Cylinder Pipeline
The results of an extensive investigation to evaluate the in-service condition and future serviceability of an existing lake water make-up pipeline are briefly described herein. The pipeline...
Combined Load Testing of Prestressed Concrete Cylinder Pipe
A series of combined load tests were run on prestressed concrete cylinder pipe in order to evaluate a proposed new method of design for pipe made to AWWA Standard C301. These tests involved...
