Lateral Analysis of Drilled Piers Incorporating Soil Variability
In probabilistic studies, the mean or expected value of the parameter in question, along with its measured dispersion or standard deviation, are determined. In this study the Three Point...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
Prediction of Concrete Creep and Shrinkage by Sampling on the Basis of Correlated Random Material Parameters
There are many random parameters which influence creep and shrinkage of concrete. In all of the previous probabilistic studies the parameters are assumed to be mutually independent random...
Orthogonal Expansion for Beam Variability
A new method for the solution of problems involving random media is proposed. The medium property is represented by a stochastic process. The method makes use of an orthogonal expansion...
Stochastic Finite Element Analysis of Frames with Flexible Connections
A procedure is proposed in this paper for the stochastic finite element analysis of frames with stochastic connection rigidity. A beam-column element is used to simulate the connection...
Damage Accumulation Models for Bridges
In the study summarized in this paper the serviceability and ultimate limit states were reviewed for concrete and steel girder bridges. A model is proposed to evaluate strength and remaining...
Actual Versus Assumed Behaviour of Girder Bridges
It is generally believed that the discrepancies between calculated and actual responses of bridges can diminish, to the point of being nonexistent, with refinement in the method of analysis....
Reliability of Cracked, Prestressed Girders
For prestressed concrete structures in non-aggressive environments or where corrosion-protected prestressing strands are used, it may be possible to allow flexural cracking into the precompressed...
Reliability Methods for Steel Members Subjected to Axial Load and Moment
There has been a significant amount of research performed on determining the reliability of elastic-plastic frames where failure is through the formation of a plastic collapse mechanism....
Reduction of Imposed Loads for Beam and Column Design
Imposed loads on beams and columns are generally reduced to effect in economy in design. A study to evaluate the reduction criteria by evaluating the Equivalent Uniformly Distributed Loads...
Reliability Analysis of Single-Headed Anchor Bolts
Several design equations for predicting the capacity of single-headed anchor bolts embedded in plain concrete have been recommended in the United States. The capacities predicted by these...
Response of Two-Span Beam to Spatially Varying Earthquake Excitation
The effect of the spatial variation of strong ground motion should be considered in the analysis and design of large structures such as bridges, lifelines, dams, etc. The stochastic response...
Applying the Time-Reliability Equation
This paper presents a methodology for rigorously including time-varying elements of reliability through the use of the time-reliability equation. An example reliability analysis which...
Stochastic Risk Assessment for Structural Safety
Through the United States the structural safety of major and/or innovative structures has become a serious concern for engineers and to the general public. The objective of this paper...
Reliability Study of Randomly Imperfect Beam-Columns
In this study, the effect of random initial geometric imperfections was treated as a set of equivalent random initial forces. This concept enables the direct employment of existing stochastic...
Building Code Requirements for Masonry Structures and Specifications for Masonry Structures
The proposed Building Code Requirements and Specifications for Masonry Structures presented in this book were developed by the Joint American Concrete Institute, American Society of Civil...
A Study in Nuclear Decommissioning
The Gentilly-1 nuclear power plant two year decommissioning project launched a series of firsts for the nuclear power industry. It was the first commercial sized plant in the world to...
Swiss Cheese Box Girders
Now going up in the French Alps, the Sylans and Glacieres viaducts have decks supported by three-dimensional arrays of concrete trusses. The superstructures look like concrete box girders...
High Strength High Rise
For the sixth time in history, a structure billed as the world's tallest concrete building (over 950 ft) is under construction in Chicago. The contractors describe the structure...
New Installation Designs for Buried Concrete Pipe
The rational development of new installation designs for buried concrete pipe is described. Over 100 analyses were performed using a new computer program named SPIDA (Soil Pipe Interaction...
