Cumulative Damage of Structures
Structural response records may be analyzed to estimate relative motions of civil engineering structures. Several methods are available for the estimation of cumulative damage on the basis...
Reliability-oriented Design of Fatigue Experiments
It is well known in the reliability analysis for structural components subjected to cyclic random load that apart from the usually model parameters uncertainties are most important and...
Modeling Errors in Fatigue Crack Growth Laws
Using the fracture mechanics approach to fatigue it is possible to update estimates of a structure's reliability against fatigue failure given new information on the state...
Reliability Revision for Structures in Service
Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available....
Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...
Fatigue Design Criteria for Welded Steel Details
A review of fatigue data and reassessment of the 1983 fatigue specification resistance functions has been conducted. Since the AASHTO specification fatigue resistance provisions were introduced...
A Fatigue Study of Prestressing Strand
Strand fatigue data reported in the literature and also from recent tests were combined to form a data base of strand fatigue data which was analyzed using regression analysis techniques....
Base Isolation for Reinforced Concrete Structures
A recent experimental program has been carried out at the Earthquake Simulator Laboratory of the Earthquake Engineering Research Center in which a 1/5th scale reinforced concrete structural...
Polymer Concrete for Structural Applications
Polymer concrete (PC) has been used extensively in the United States primarily as a repair material for portland cement concrete. The excellent flexural and compressive strength durability...
Chemical Admixtures for Concrete, What is in Them for the Structural Engineer?
The paper summarizes the effect of admixtures on the economy in construction of concrete structures, on their strength, and on their durability under a variety of service conditions. As...
High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...
Structural Considerations of Cellular Concrete
Although not normally considered to be a structural material, cellular concrete possesses characteristics which may result in its having structural applications in building and structural...
Concrete Shell Design for Membrane Stress
A methodology is presented which covers the design of reinforced concrete shells for membrane stress. The methodology follows the strength design method of the ACI 318-83 Building Code...
Large Reinforced Concrete Active Reclaim Silos
The design and construction of large reinforced concrete shell silos used to provide economical short-term protected storage for coal and lignite in the active reclaim systems of power...
Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...
The Ultimate Load Design Method of R/C and P/C Shell
Based on the testing results of 20 full size shells and models, the ultimate load analysis method is proposed to design four different kinds of reinforced concrete shallow shell structures....
Substitute Wind Concept for Elastic Stability of Cooling Tower Shells
The influence of the nonaxisymmetric wind distribution on the stability behavior of cooling tower shells is examined. It is demonstrated, considering about 50 cooling tower shells, that...
Applied P-Delta Methods in the Design Office
At first glance some axioms of a P-Delta analysis appear to be paradoxical. First, the P-Delta effects are a direct function of the depth of the structure parallel to the wind direction....
Practical Application of PR Connections and Second Order Analysis
In the present LRFD Specifications type PR (Partially Restrained) connections are described as those where the connections of beams and girders possess an insufficient rigidity to hold...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
