Freezing and Thawing of Soil-Water Systems
This book presents a state-of-the-practice review on freezing and thawing of soil-water systems through ten interrelated papers on this subject. The papers review the following topics:...
Richart Commemorative Lectures
The geotechnical specialty known as soil dynamics has developed during the past 25 years from a minor role to a mainstream discipline. Professor F. E. Richart has played a major role in...
Computing in Civil Engineering
A broad spectrum of computer applications in civil engineering is covered in 73 papers presented at the Third Conference on Computing in Civil Engineering. Emphasis is on microcompters...
Emerging Computer Techniques in Stormwater and Flood Management
These proceedings identify and assemble information on recent applications of mini- and microcomputer technology to problems in urban stormwater and flood management. Instrumentation and...
Dynamic Response Correlation of Cylindrical Tanks
The May 1983 Coalinga Earthquake provided an opportunity to correlate earthquake performance of cylindrical liquid storage tanks with behavior observed in laboratory shaking table experiments....
Traffic Reroute
During reconstruction of Pittsburgh's Interstate 376, traffic and passenger diversion efforts, more extensive than ever before, were undertaken. Eight percent of the $62 million...
Seismic Qualification of Main Control Boards by Combined Mathematical Model and In-situ Modal Test
By adjusting the stiffness of the model, mode shapes and frequencies can be matched to those from the in-situ tests, thus giving a verified and representative model. With the verified...
Seismic Evaluation of Non-Seismically Designed Existing Magnox Nuclear Power Plants
Special procedures included on-site testing with a portable shake table, low vibration testing using a structural dynamics analyser, and on-site inspections. The low vibration testing...
Probabilistic Analysis of Impact Loading Conditions
Probabilistic methods are developed for the analysis of random impact loading conditions that arise from oblique, noncollinear, and spinning missile impacts. Models are developed for the...
Nonlinear Analysis of Reactor Vessel & Core Supports Subjected to Accidental Impact Loads
Nonlinear dynamic analyses of the reactor vessel, its support systems, the core and the core supports were performed to evaluate the consequences of such drops. Damage was defined in terms...
Sensitivity of Peak Dynamic Responses to Input Factors
Responses have been calculated for the Zion Unit 1 plant, using the SSMRP computer code SMACS, as part of the seismic probabilistic risk assessment performed by the Seismic Safety Margins...
Seismic Capacities of Masonry Walls at the Big Rock Point Nuclear Generating Plant
An evaluation to determine the ability of selected concrete block walls in the vicinity of essential equipment to withstand seismic excitation was conducted. The seismic input to the walls...
Coupled Vertical-Rocking Response of Base-Isolated Structures
A base-isolated building can have a small horizontal eccentricity between the center of mass of the superstructure and the center of rigidity of the supporting bearings. The structure...
The Response of Steel Containment Models to Internal Pressurization
To obtain insight and data on the response of containment vessels subjected to beyond design basis accidents, four 1/32 scale steel containment models have been subjected to internal overpressurization,...
Preliminary Analysis of Large Penetration Enclosures for Containment Vessels Subject to Beyond Design Basis Loadings
Numerical simulations of the macro-deformations of the sealing surfaces (gasketed junctures) of a PWR steel containment vessel's equipment hatch subjected to accident loadings...
Major Considerations in Scale Modeling of Reinforced Concrete Containment Structures
Reinforced concrete containment structures pose unique modeling problems, especially when leakage integrity is of interest. This paper presents a general discussion of modeling considerations...
Design Verification of HVAC Duct Turning Vanes in Nuclear Power Plants
HVAC ducts in nuclear power plants utilize short radius elbow construction with turning vanes to minimize the space requirement for duct work and to reduce flow losses in the elbows. Turning...
A Correlation Study on the Spectrum Decomposition Method
The major elements of the Spectrum Decomposition Method (SDM) are reviewed together with its automated process for generation of in-equipment response spectra (IERS). The floor required...
Fluid Structure Interaction Analysis of a Concrete Suppression Chamber of Mark I Containment System
Recent studies have demonstrated that the interaction between a structure and fluid can have a significant influence on the response of the overall system when subjected to certain dynamic...
A Pseudo Response Spectrum Method for Mark I Loads
A pseudo base motion response spectrum method is developed to uniquely evaluate the periodic condensation oscillation and chugging drag loads that may occur on submerged structures within...
