Wind Loads on Large Broadcasting Antennas: Records and Elaborations
Alternative estimations of the 50-year gust winds from the data available in typical Italian sites of broadcasting antennas are summarized and compared with the design winds suggested...
Safety Analysis of Steel Building Frames Under Dynamic Wind Loading
A method is presented for evaluating the lifetime risk of failure, in terms of probability of excessive inter-floor deflection, for a class of steel building frames subjected to dynamic...
Stochastic Evaluation of Landing Pier Construction
This paper discusses the process of determining the magnitude of external force such as wind and wave pressure exerted on marine structures under construction, and the learning curve of...
Wind Vs. Seismic Design
This paper is concerned with the reliability analysis of building structures subjected to multiple natural hazards (seismic and wind in this case) within the framework of contemporary...
Multi-Hazard Risk Assessment of an Offshore Structure
This paper develops and illustrates a methodology for multi-hazard modal risk assessment. The case study involves assessing risk to an offshore structure in a load environment consisting...
On the Failure Probabilities of R/C Chimneys
A procedure to estimate failure probabilities of structural systems such as reinforced concrete (R/C) chimneys under severe wind loading which allows for considering realistic correlation...
Design of Aircraft Wings Subjected to Gust Loads: A System Reliability Approach
A method for system reliability based design of aircraft wings is presented. A wing of a light commuter aircraft designed according to the FAA regulations is compared with one designed...
Nonlinear Dynamic Response of Industrial R/C Chimneys
Gust response factors (GRF) based on nonlinear dynamic analysis including the P? effect are calculated. All sample structures analyzed show clearly that, for wind speeds exceeding the...
Some Insight in Autoregressive (AR) Spectral Modeling
The difficulties associated with the determination of reliable autoregressive (AR) approximations of the Pierson-Moskowitz and Davenport spectra are examined from the standpoint of developing...
Reliability of Control Systems of Building Structures by Active Tendons
In this paper, a numerical assessment on the reliability of a control system of building structures by active cables is performed. Some control experiments on a 23-story shear-wall building...
The N-Year Maximum Mean Values and the Coefficients of Variation of Loads Subjected to Port and Offshore Structures
It is necessary to know mean values and coefficients of variation of loads in order to verify the safety of structures. In this paper, the N-year maximum mean values and the coefficients...
Extreme Value Distribution for Stochastic Processes Subject to a Full Load Climate
Reliability analysis of structures subject to environmental loads generally involves load effects which are properly treated as stochastic processes, and requires determination of the...
The Extremes of Combinations of Environmental Loads
The objectives and the general approach of an offshore environmental data and extremal analysis are described. The intention is to develop long-term design values of wave, wind and current...
Structural Safety and Reliability
This proceedings of the 5th International Conference on Structural Safety and Reliability (ICOSSAR '89) held on August 7-11, 1989 in San Francisco, California contains almost...
Tomorrow's Energy Today
If concerns about global warming, acid rain and air pollution continue to mount, replacements for fossil fuels�for a century the dominant power source in the U.S.�will be necessary to...
Museum Showcases the Future
On May 4 in Philadelphia, the Franklin Institute's new wing, called the Futures Center, will open to the public. When the institute's neoclassic main buiding...
Modeling a Wind-Mixing and Fall Turnover Event on Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic model of Chesapeake Bay has been developed. Results from application of the model to one of the three data sets employed in the verification...
Model Comparisons of Oyster Recruitment in Delaware Bay
A second order particle trajectory model using surface currents from a three-dimensional model of Delaware Bay was run for a period equivalent to the larval stage of the oyster C. virginica...
Glacial Icemelt in the Wind River Range, Wyoming
The Wind River Range of Wyoming contains the greatest concentration of glaciers in the American Rocky Mountains with two of the larger glaciers being Dinwoody and Gannett Glaciers. This...
