Mechanical Aspects of Intake Gates at John Hart Dam
As part of the John Hart Dam rehabilitation program completed in 1988, six new intake gates complete with guides and hydraulic operators were installed replacing the existing gates and...
Theoretical Study on Capture Chamber with Lateral Entrance
A capture chamber with lateral entrance can be used in a pneumatic wave energy conversion system. In this paper, the output power coefficients of the capture chamber have been calculated...
U.S. Coast Guard Experience with Commercial FRP Vessels with Respect to Structural Reliability
The U.S. Coast Guard currently inspects over 1000 fiber reinforced plastic (FRP) vessels used in commercial passenger service. The designs include monohulls, catamarans, hydrofoils and...
Selected Earthquake Engineering Papers of George W. Housner
Sponsored by the Structural Division of ASCE. This volume collects key papers on earthquake engineering by George W. Housner, who more than any other...
Effects of Uncertainties in Component Fragilities on Lifeline Seismic Risk Analysis
Accurate calculation of the seismic risk for lifelines requires modeling the system as a function of its components, and requires accurate modeling of two engineering factors: (1) the...
Structural Vibrations Produced by Ground Motion
Originally published in: Transactions ASCE, Vol. 122, 1957, pp 705-721...
Water Jets Fight Silt
In the largest U.S. application to date, an array of hydraulic jets is being used to scour a ship berth at the Port of Grays Harbor on the coast of Washington. The system has been in place...
Moving Intermodal Containers Over Urban/Suburban Highways
Due to standardization, to date most containers basically fit the U.S. highway environment, which was the entire original intent of intermodal transport. The paper presentes the results...
Floating Membrane Supertankers: Are They Feasible?
Optimal shapes of long cylindrical membrane containers are obtained by restricting the circumferential membrane stress to be tensile and constant throughout the tanker. Optimality is achieved...
Floor Vibrations ? Tips for Designers
The purpose of this paper is to suggest a number of practical concepts which can be used to improve the performance of floor systems subject to occupant induced motion from either walking,...
Optimal Location of Active Controllers Subjected to Seismic Excitation
In the application of structural control to seismic structures certain locations are advantageous for placement of the actuators. These locations reduce the structure's response...
A Family of Concurrent Algorithms for Transient Finite Element Solutions
We derive a family of methods for solving the equations of motion arising in structural dynamics which makes effective use of the architecture of concurrent computers. The algorithm is...
Effects of Vertical Motion on the Inelastic Behavior of Highway Bridges
The response of typical highway bridges to the vertical component of earthquake ground motion has a significant effect on their elastic behavior. When vertical motions are considered along...
Strong-Motion Records from Buildings
Since the establishment of the California Strong Motion Instrumentation Program in 1972, over 90 buildings have been instrumented extensively to measure their response during earthquakes....
Seismic Instrumentation and Its Implication for High-Rise Buildings in Japan
An outline of the present state of the strong earthquake motions observation systems in Japan and an example of the obtained records of an earthquake and its simulation analysis of a high-rise...
Earthquake Induced Cracking in Concrete Gravity Dams
An important nonlinear behavior in the earthquake response of concrete gravity dams is the formation and propagation of tensile cracks in the concrete. The earthquake response of a typical...
Analysis for the Seismic Response of Liquid Containers
An analytical model is presented for the nonlinear response of fluid containers whose bottom may separate from and lift off their foundation, during base excitation. First, the hydrodynamic...
Seismic Performance of Existing Building in New York City
Strength-based damage indices depending on structural shear capacity and earthquake intensity are used to predict the seismic performance of existing buildings in New York City. Nonlinear...
Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....
Analysis of Barrier Island Dynamics for Ship Channel Planning at Ship Island, Mississippi
Ship Island is located among a chain of barrier islands approximately 18 km south of Biloxi, Mississippi. During initial construction of Gulfport Harbor Ship Channel, 1901-1905, the channel...
