Optimum Seismic Structural Design with Tendon and Mass Damper Controls and Random Process
This paper describes the optimization of structural weight for seismic structures implemented by active control systems. The instantaneous open-loop optimal control algorithm is used for...
Bidirectional Seismic Response of Simple Structures
For design purposes it has been common to consider that seismic excitations act in one direction at a time. Analytical studies over the past decade have indicated that this may not be...
Uncertainty and Conservatism in the Seismic Analysis of Nuclear Facilities
Traditionally, seismic analysis and design of nuclear power plant structures are performed using deterministic procedures. In order to address the issue of the likelihood of failure, probabilistic...
Behavior of Concrete Bulkheads in Salt Drifts
Parameters studies of the behavior of a plug made from expansive concrete have been performed. Such plugs are now being field tested for sealing boreholes, shafts and drifts at an underground...
Effects of High Pressure and Temperature on HCP
A modification of fabrication techniques for cement paste can significantly affect its properties. Specifically, the static compressive strength can be increased over that of specimens...
Influence of Surface Conditions on Surface Temperature
Geotechnical engineers working in areas of discontinuous permafrost are frequently faced with the necessity of designing facilities with a minimum of thermal disturbance. Construction...
Ice Forces on Bridge Piers
The force that river ice exerts on bridge piers has been studied in the field and with models in the laboratory. Ice forces are a function of the strength, thickness, failure mode and...
Lifeline Risk Analyses: The Mokelumne Aqueduct Study
Probabilistic risk analysis methods are applied to the evaluation of seismic and non-seismic vulnerability of a 25-kilometer length of a major lifeline aqueduct system. In addition to...
Quality in the CM Constructed Project
The services of the testing laboratory on construction projects have not generally been considered as part of the construction management function. If the intention of construction management...
Continuous Loading Consolidation Testing Using a Microcomputer for Control and Data Acquisition
An overview of some of the methods of one-dimensional consolidation testing currently in use is presented, including the load-increment test, the constant rate of strain test, the constant...
A Power Planning Model for Seismic Risk Zones
We present a model to configure a nuclear power system consisting of plants and the distribution network. In the model, we quantify seismic risk as comprehensively as possible in terms...
Microcomputer Construction Operations Simulation
This paper summarizes the current status of an ongoing research project whose objective is to collect time data from videotapes of field construction operations and use the data as input...
Assessing Biological Effects of Contaminants In Situ
This paper presents a monitoring strategy for assessing the effects of anthropogenic contaminants on aquatic organisms. This strategy takes advantage of our increased understanding of...
Effectiveness of Extended Detention Ponds
Field and laboratory studies of the performance of detention facilities for the removal of selected pollutants from urban stormwater were conducted. The laboratory studies consisted of...
Techniques for Rapid Assessment of Seismic Vulnerability
Under the impetus of a growing awareness of seismic hazards, there is an increasing effort being devoted to assessing the seismic vulnerability of existing buildings. For many professionals...
Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...
Seismic Evaluation of Lifeline Systems?Case Studies
This book contains the papers presented at the technical session titled Seismic Evaluation of Lifeline Systems?Case Studies at the ASCE Fall Convention in Boston, October 27-31, 1986....
Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...
Experimental Assessment of Performance of Bridges
Among the papers in this book, five assessed the global bridge behavior and the three concentrated on bridge decks. The bridges assessed include prestressed steel plate girder and truss...
Concrete Rehabilitation Options and Solutions
This paper demonstrates the basic steps for a successful rehabilitation program using a case study of the rehabilitation work for the NASA/JPL 64-meter deep space communication antenna....
