This paper summarizes the results of a comprehensive three-dimensional dynamic analysis of tall buildings subjected to fluctuating wind forces. Random vibration theory is used to relate...
Time Dependent Stochastic Characteristics of the Lateral Random Vibration of Tall Structures with Circular Cross-Section
From full scale measurement of the pressure field at three levels of a concrete chimney with 230 m height the lift coefficient is deduced and the lateral oscillation is investigated. The...
Reliability Analysis in Estimating Turbulent Wind Force on Offshore Structures
This paper presents the results of a reliability analysis carried out to estimate low frequency turbulent wind drag force (including extreme values) acting on a floating offshore structure....
Identification of Critical Load Distributions for Wind Loading
For practical application as well as for sophisticated investigations, the time dependent stochastic wind process has to be simplified in terms of input data to the calculation. Usually,...
Optimal Distribution of Tuned Mass Dampers in Wind-Sensitive Structures
Modern high-rise buildings are susceptible to excessive accelerations at the upper floors in wind storms due to flexibility and low damping. In order to keep acceleration levels below...
Reliability of Bridges in Turbulent Wind
The present study investigates the stability of bridge motion by means of almost sure or sample stability criteria. An asymptotically exact approximation for the top Lyapunov exponent...
Buffeting Response of Bridges
The present study provides a theoretical analysis of the behavior of the response of long-span bridges to turbulent wind loads in the region of stable motion. The analysis is based on...

The paper summarizes some results of the analyses of two tall broadcasting towers, obtained by means of a specially developed numerical procedure taking into account all relevant nonlinear...
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...
Reliability-Based Design of Tunnel Support in Jointed Rock
The presence of joints in a rock mass may cause local instability of the tunnel support and its effect on safety should be included in design. Because of significant uncertainties in the...
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...
