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...

Nonlinear Load Exceedances with Correlated Sustained Load Process
Past studies on nonlinear structural response of a single member only concerned with independent, identically distributed load magnitudes. When the structural member is subjected to cumulative...

Extreme Value Distribution for Stochastic Processes Subject to a Full Load Climate
Reliability analysis of structures subject to environmental loads generally involves load effects which are properly treated as stochastic processes, and requires determination of the...

The Extremes of Combinations of Environmental Loads
The objectives and the general approach of an offshore environmental data and extremal analysis are described. The intention is to develop long-term design values of wave, wind and current...

Probabilistic Models for Loads Due to Bulk Solids
This paper presents two probabilistic models for loads due to bulk solids. One model seeks to obtain an accurate presentation of the loads; the model is used as a basis for a systematic...

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...

Statistical Analysis of Australian Ground Snow Loads
This paper is concerned with the statistical analysis of snow data from the alpine areas of southeastern Australia (above 1200 m). In these areas, the local variation is large and contour...

Optimization of Structures Under Stochastic Loads
A method for design under multiple stochastic loads based on optimization is developed. The objective function such as cost is minimized under the constraint that the probabilities of...

Optimum Studies of Coefficient Variation of UBC Seismic Forces
This paper presents an optimization algorithm for finding optimal parameters of a nondeterministic structure subjected to UBC seismic load for both normal and lognormal distribution models....

Probabilistic Traffic Load Models and Extreme Loads on a Bridge
This paper contains a summary of the intensive traffic measurements collected in France and Europe, and of the probabilistic distributions adopted for the main parameters. The evaluation...

Reliability-Based LRFD For Bridges: Theoretical Basis
This paper develops a theoretical basis for obtaining probability-based load combination criteria for structural design. For choosing the load combinations and for determining the factors...

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...

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...

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...

Probabilistic Basis for Bridge Design Codes
There is a growing interest in the development of rational design criteria for bridges. The fundamental problem is evalution of the loads and load carrying capacity. However, load and...

LRFD for Engineered Wood Construction: ASCE Pre-Standard, Wood Industry Initiative
The structural wood community in the United States is in the process of developing a reliability-based consensus Load and Resistance Factor Design (LRFD) standard for engineered wood construction....

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-Based Analysis of Shallow Foundations
The effects of different parameters on the reliability of shallow foundations are examined. It is found that the footing depth, the footing length, and the load ratio have almost no effect...

Reliability Analysis of Axially Compressive Members
In the steel structure design code (TJ17-74) in China, a single curve was adopted for designing axially compressive members and the reliability of the column analyzed previously was based...

Reliability Synthesis of CFRP Laminated Plate
The paper presents a formulation of shift synthesis to improve the reliability of fiber reinforced plastic (FRP) laminated plates with uncertain elastic constants and lamina strength....
