Safety Levels of Reinforced Concrete Box Culverts for Installing Power Supply Cables
The authors have examined the applicability of reliability-based design to the existing reinforced concrete box culverts for installing power supply cables. The lowest safety index of...
Reliability Study of Ferrocement Slabs Under Cyclic Loading
A simple probabilistic approach to fatigue strength studies for ferrocement slabs is presented: A preliminary experimental program to obtain the relevant statistics was conducted and the...
An Investigation of Live Loads on Concrete Structures During Construction
Slab formwork live loads include the weight of equipment, construction material storage loads, and impact loads when placing the concrete. In this paper material and equipment loads are...
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...
Background Studies for the Determination of Strength Functions in Eurocode 3?Design Rules for Steel-Structures
At present common unified rules for the design of Civil engineering structures are being prepared on the initiative of the Commission of the European Communities. Eurcode 3, which gives...
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...
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...
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,...
Industrial Strength 3-D
Williams assesses the benefits of using three-dimensional computer modeling in the design of industrial structures, comparing the reality in which the computer is a useful tool for engineers...
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...
