Safety Assessment Methodology for Construction Operations
There are many factors that affect the safety of construction operations which might lead to failures and accidents. The factors are associated with random, human-based or system uncertainty....

Load Path Dependence of Structural Systems
This paper presents the results of an investigation into the sensitivity of the behavior of framed structures to load path. Simple but realistic structural steel frames have been designed...

Structural Error Identification for Control of Construction Accuracy
In cases of large-scaled structures it is very important to keep the criteria of construction accuracy and therefore to correct construction errors if any considerable errors are found...

Application of Probabilistic Methods in Construction Industry
Recent attempts for theoretical development and engineering application of probabilistic methods, which have been carried out in a Japanese engineering and construction company, are summarized....

Stochastic Finite Element Analysis of Metal Plate Connected Wood Trusses
A stochastic finite element approach is developed for use in ananlyzing metal plate connected wood trusses. The procedure uses linear beam-column elements to model the wood members. The...

Model Identification of an Arch Bridge for Dynamic Analysis
The dynamic responses of a steel deck tension-tied arch bridge subjected to earthquake excitations were investigated. The 189 m (620 ft) Birmingham Bridge located in Pittsburgh, PA was...

Statistical Fatigue Properties of Carbon Steels for Machine Structural Use Based on JSMS Database on Fatigue Strength of Metallic Materials
A database on the fatigue strength of metallic materials was compiled by collecting the experimental fatigue data of the last 20 years in Japan on a nationwide scale as a joint project...

Distribution of Variance of Fatigue Lives of Ferrous Metals by the Analysis of Fatigue Strength Database
The purpose of this study is to determine the distribution characteristics of variance of fatigue lives of carbon and alloy steels, especially from the viewpoint of their dependence on...

Fatigue Reliability of Steel Structures in the Presence of Residual Stresses
An extended model for the assessment of fatigue reliability of steel structures in the presence of residual stresses is developed. The model explicitly includes the uncertainties of the...

Fatigue Reliability and Remaining Fatigue Life of Existing Steel Rail-Road Bridges
This paper presents a fatigue reliability model for the reliability-based evaluation of remaining fatigue life of existing rail-road bridges. It is demonstrated that the simple fatigue...

Fatigue Reliability of Prestressed Concrete Bridges
Experimental studies indicate that fatigue is a random phenomenon. Therefore, the approach is based on probabilistic methods. The fatigue life of the prestressed concrete girder is estimated...

Qualitative Design for Safety and Reliability
This work aims at developing a fundamental methodology for the qualitative reliability design of machines and structures to cope with the present situation of small production with a wide...

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...

Load Modelling for Single Story Steel Buildings
Realistic load assumptions for single story buildings are thus far complicated by the insufficient state of the modelling of individual loads as random variables or stochastic processes...

Evaluation of Lifetime Risk of Structures?Recent Advances of Structural Reliability in Japan
The Task Committee on Structural Safety and Reliability of the Japan Society of Civil Engineers has made survey of recent advances in the field of structural reliability. Consequently,...

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...

Reliability of Steel Columns Subjected to Buckling?Comparison of International Standard Codes of Design
Standard codes of design represent the phenomenon of buckling by means of a curve taking into account random structural imperfections. The author suggests a probabilistic method to evaluate...

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...

Present and Future Developments in Steel Design Codes
Steel structures design codes with load and resistance factors (or 'partial factors') which are based on first-order probabilistic concepts are now in use in...
