Parallel Algorithms for Structural Optimization Under Dynamic Loading
Parallel algorithms and strategies are outlined for optimal design of frame structures subjected to dynamic earthquake loading. Parallelism is extracted in six areas: substructuring of...
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,...
Shallow Foundation on Sand Underlain by Soft Clay with Geotextile Interface
One technique for improving the load-bearing capacity of shallow foundations on soft clay soil is to construct them over a compact granular fill laid over the clay layer. However, the...
Design of Ash Basin Dike across Cove
Embankments built over soft, unstable foundation materials had required that the materials either be removed or reinforced. With the introduction of geotextiles, it is now economically...
Guidelines for Design and Construction of Pozzolanic Stabilized Base Course Mixtures
The American Coal Ash Association (ACAA) has developed a manual of recommended practice which contains guidelines for the design and construction of pozzolanic stabilized base course mixtures...
Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...
Effects of Driver Factors and Training on Wrecks
A training program for professional drivers is reviewed. The effects of driver factors, as well as their training, on accidents is presented....
Design Considerations for Trucks in Work Zones
In an Eastern state a 3. 8 mi (6. 2 km) work zone had 14 accidents during a project duration of 120 days. Eleven of the 14 accidents occurred at temporary crossovers where traffic was...
Accommodating Larger Trucks at At-Grade Intersections
When a particular intersection serves a high volume of large truck traffic, design considerations should reflect the presence of those larger vehicles. This paper discusses three intersection...
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...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
Probabilistic Prediction of Pile Group Capacity
A reliability analysis of a group of free standing piles in clay is carried out using Monte Carlo simulation. The pile material strength, soil capacity, and the load on the pile group...
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...
