Subsurface Savings
Less conservatism than usual in designing building foundations is being accepted or demanded by some owners to save money. The article describes four examples of cost-cutting innovations,...
Rennick Yard RCC Pavement Design and Construction
Rennick Yard roller compacted concrete paving project consisting of 136,000 multiplied by (times) yd**2 (113,710 m**2) was completed in June 1986. The design load for this project was...
Geosynthetics for Soil Improvement: A General Report and Keynote Address
The paper summarizes major developments in the field of geosynthetics since the previous symposium in 1980. The paper addresses the engineering functions of major types of geosynthetics,...
Impact of International Competition on Construction Technology?A Perspective
The strong showing by non-U. S. contractors in the development of new construction technologies has had a significant impact on the redistribution of construction dollars in world markets....
The Swedish Approach to Construction Technology Development
Swedish building and construction work expanded very fast both technically and industrially during the two decades following 1950, domestically first, later also abroad. The 1980s has...
Winning With Advanced Construction Technology
At least three driving forces in U. S. construction markets indicate the increasing importance of advanced technology: the technical complexity of constructed facilities is increasing;...
Equipment Automation and Its Impact on Construction Technology
The Naval Construction Force is facing a shortage with their horizontal construction capability and their equipment is not designed to function in a modern war environment. One solution...
Competitiveness in Construction
This paper addresses the competitiveness of the U. S. construction industry. The goal is to define a possible scope for the subject, outline some key issues and dimensions, and examine...
Modeling Fatigue Crack Growth Resistance, dN/da
In the fracture mechanics approach to fatigue, da/dN is correlated with the cyclic range of the stress intensity factor, ?K; the resulting relation, da/dN=f (?K), is commonly called the...
Load Combinations for Codified Design
Loading requirements used in current standards for structural design are not consistent in their conceptual basis, appearance or use. Unified limit states design procedures for structures...
Load-Sharing and Reliability of Wood Systems
A methodology for the study of reliability of light-frame wood structural systems is presented. Reliability levels associated with the bending strength limit state of such systems are...
Development of Bridge Design Code
Load and resistance parameters for bridges involve uncertainties due to natural randomness, imperfect models or human errors. Because of these uncertainties, absolute reliability is not...
Probabilistic Load Combinations in Nuclear Structures
A variety of loads affect a nuclear power facility during its lifetime. The magnitudes or intensities of these loads are uncertain, and for some of them, their time of occurrence is also...
A Reassessment of Codified Limit States Design
This paper examines the nature of design codes and their relation to engineering practice. It suggests that codes impose unjustifiable and, in the long term, destructive constraints on...
Pore Pressure Development: Probability Analysis
The development and subsequent dissipation of excess pore pressure, p in a soil deposit subject to an external load is examined using probability concepts that account for uncertainties...
Dependence of Fatigue Damage on Loading Amplitude Variability
Welded steel specimens have been tested under variable amplitude loadings to determine the extent to which fatigue life is affected by the rate of amplitude variability of the loading...
Effects of Random Material Properties and Loads
The variability of slab deflections is estimated from analytical expressions accounting for random variations of spatially distributed loads and material properties (stiffness parameters)....
Reliability of Geometrically Nonlinear Structures
A procedure for first- and second-order, finite-element reliability analysis of geometrically nonlinear structures under static loads is presented. Structures are either linear or nonlinear...
Multicriterion Reliability-Based Optimization of Structural Systems
The optimization of nondeterministic structural systems under random loads is currently performed by single-criterion reliability-based optimization methods. However, in structural design...
Analysis of Bridge Truck Loads
The development of the reliability-based load and resistance factor design (LRFD) methodology requires uncertainties in loads and resistance be quantified. In the load capacity evaluation...
