Manhole Rehabilitation
Manholes are frequently the forgotten element in infrastructure renewal. When they aren't properly maintained they allow excess water into the sewer system, and structural...
Air-Water Mass Transfer
This monograph, Air-Water Mass Transfer: Selected Papers from the Second International Symposium on Gas Transfer at Water Surfaces, consists of papers presented at the Symposium which...
Retrofitting Fossil Plant Facilities Structural Perspectives
This publication, Retrofitting Fossil Plant Facilities: Structural Perspectives, was prepared by the Retrofit Task Committee of the Fossil Power Committee of the American Society of Civil...
Analyzing Risk
Engineers designing major projects must often grapple with large areas of uncertainty�from estimating the seismic hazard to a nuclear powerplant to the potential effects of decades of...
Anchors in the Desert
The Southwest desert isn't usually thought of as a hotbed of seismic activity, but earthquakes have occurred there. And if Arizona's Stewart Mountain Dam, a double-curvature...
Freudenthal Lecture Developments in Structural Reliability
Rather than reviewing the details of developments in structural reliability theory and its implementation over the last few decades, more recent and more relevant reliability issues are...
Reliability of Large Technological Systems
Codes and regulations regarding large technological systems of growing complexity should take into account the increasingly sophisticated analysis tools that have been and are being developed...
Probabilistic Assessment of Wind Loading For Structural Analysis
Records of extreme annual gust velocities from 11 weather stations in central-southern Brazil, classified according to orientation (octants) and type of storm (TS and EPS winds), result...
Wind-Induced Response of Torsionally Coupled Buildings
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...
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....
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...
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...
Reliability of Overhead Transmission Lines Subjected to Wind Action
The probability distribution of the strength of steel towers used in transmission lines, due to wind excitation, is evaluated on the basis of test results of 72 towers of various designs,...
Fully Nonlienar Models to Simulate Structural Response to Wind Loading
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...
On the Reliability of Offshore Platforms Against Random Sea Waves and Earthquake Motions
Dynamic response of offshore structures to random sea waves and strong earthquake motions is investigated. The wave-structure interaction is represented using the generalized Morison equation...
Spectral Analysis and Fatigue Reliability Assessment for Offshore Structures
This paper presents a cumulative fatigue damage formulation in stochastic variable space using bilinear SN model and the Palmgren-Miner's rule for evaluating the fatigue reliability...
Response Surface Fitting in Offshore Structural Design
Failure probability estimation of complex offshore structures requires the modeling of the system behavior in terms of all uncertain parameters. This paper investigates the applicability...
Collision Risk Analysis Fixed Platform and Semisubmersible
This paper summarizes the North Sea experience pertaining to mooring line failures of conventional 8 and 12 anchor line systems. Mooring system calculations, experience and test results...
