Practical Analysis of Flexibly-Connected Building Frames
Modeling of flexible connection behavior as elastic-perfectly plastic is proposed for analysis of building frames, and results based on this idealization are compared with fully non-linear...
Comparison of the Third and Fourth Edition of the Guide: What is New and Different
The fourth edition of the 'Guide to Stability Design Criteria for Metal Structures' is a unique collection of ideas and information on stability problems. It...
Centrally Loaded Columns
The paper has given a detailed description of the chapter on centrally loaded columns that will appear in the 4th Edition of the Structural Stability Research Council 'Guide...
Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...
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....
Dynamic Fracture Toughness of Rail Steels
As new premium alloy rail steels exhibit increased wear resistance and as track lubrication is used, the failure mode for rails is shifting from wear to fatigue. Elastodynamic finite element...
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....
Axial Fatigue Model for Wire Rope Strand
A numerical fatigue model for cables and rope strand subjected to fluctuating axial tension has been developed. This model determines the maximum wire nominal and Hertz contact stresses,...
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...
Second Order Analysis of a 47-Story Building
A modern day second order analysis and ultimate strength review is made of a hypothetical 47-story unbraced frame designed under the 1969 AISC Specification. The original design is part...
Tall Building Stability -- Practical Considerations
Simple techniques for including lateral stability effects in the design of tall buildings are proposed. The application of these techniques in the design of a 66-story building is described....
Frame Stability - A Canadian Designer's Approach
The deficiencies and fallacies of the simplistic effective column length approach to frame stability are demonstrated through its application to a 57-story rigidly framed building structure....
Application of a Hybrid Strategy for Structural System Reliability Analysis
The authors have attempted to explain a strategy for structural systems reliability calculations. In essence, it involves the use of different methods at appropriate times in the search...
