On the Performance of a Wave Power Converter
This paper presents the KN-principle for wave - power conversion. The principle and components of the wave power converter are described and some practical relations are presented in order...
The Effects of Earthquakes on Power and Industrial Facilities and Implications for Nuclear Power Plant Design
Fifteen earthquakes, ranging from magnitude 5.2 to 8.4 on the Richter scale that have occurred in five countries since 1952, were studied. This report documents the performance of power...
Taipei Trade
The appearance of this building is remarkable�so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...
Capacity Increase of Multi-Jet Pelton Turbines
The recent connection to the grid of large capacity thermal stations, to meet the increasing demand, has entailed an evolution in the type of services required from storage plants with...
Hydraulic Machines Model Acceptance Tests
The article begins with a description of the modern test installations, giving the dimensions of the models most frequently used and the head heights. Attention is then given to the most...
Hoover Dam Earthquakes Reconsidered
In 1936 and 1937 as the water rose behind Hoover Dam, earthquakes were felt in the Boulder City area and as far away as Las Vegas. Interest in induced seismicity was renewed in 1967 with...
Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...
Dam Safety Relating to Merwin and Yale Hydroelectric Projects
This paper describes the safety investigations performed to evaluate the dams, associated with the Merwin and Yale Hydroelectric Projects, for the effects of severe floods and earthquakes....
Simplified Model for Micro-Hydro Feasibility
A computer model was developed for evaluating the preliminary hydraulic and economic feasibility of potential micro-hydro development sites. Among the main objectives of the model are...
How To Design Highway Retaining Walls?A Practical Application of CADD
The recent work developed at the University of Missouri-Rolla (UMR) including optimization algorithms and two computer programs, ODSEWS-2D-II and ODRESB-3D are discussed. Several numerical...
Rebuilding Mexico City
After the September 19, 1985 earthquake in Mexico City, officials had to cope with a massive volunteer effort to inspect damaged and destroyed structures. Over a thousand engineers, contractors,...
The Mexican Earthquake: A Firsthand Report
The Mexican earthquake of September 19, 1985 was most peculiar, because of the combination of its intensity, regularity, and duration. No other earthquake has had an intensity of IX, at...
Liability: Problem or Crisis?
Engineering firms are being hit with liability insurance rate increases of 30%, 50% or more. Deductibles are being raised and the maximum coverage is being decreased. Some firms cannot...
Preliminary Seismic Risk Maps for Puget Sound
Ground shaking during Puget Sound earthquakes is characterized by irregularly shaped areas of high intensity ground motion, not all of which are correlated with soil type. Simulation of...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...
Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
Earthquake Risks to Utah Water and Gas Systems
Designed to guide local earthquake hazard reduction programs, this study estimates direct aggregate earthquake damage to Davis and Salt Lake County utilities. For making these loss estimates,...
A Case Study of the Behavior of Seaport Facilities During the 1978 Miyagi-Ken-Oki Earthquake
This paper assesses seismic response characteristics of seaport facilities during the 1978 Miyagi-Ken-Oki earthquake by (a) compiling and assessing documented information from post-earthquake...
The Effects of the 1985 Mexico City Earthquake on Underground Water & Sewer Pipelines
The 1985 Mexico City Earthquake left thousands dead and many thousands more without shelter. The visible damage was immense and terrible, and familiar to people around the world through...
