Partnerships with SOBA
During the past 25 years, the number of registered watercraft tripled to the current number of 17.8 million registered watercraft in the USA. To meet a growing demand for safe waterway...

Seismic Hazard Analysis of Buried Pipeline for Design
This paper concerns mainly the following three items on seismic hazard analysis of buried pipeline for design: (1) effects of pipeline length on risk, (2) effects of local site conditions...

Is It Good Business to Be a Citizen Engineer?
When does community involvement cloud the engineer's judgment? Does the engineer have to sacrifice business success in the name of public service? The first canon in the ASCE...

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...

Excavating, OSHA-Style
When the Occupational Safety and Health Administration implemented its new, tougher trenching guidelines in July 1990, the agency opened the door for inventive excavation techniques. Contractors...

Man and Huge System Interaction
In many cases of disaster, the causes of failure of huge systems are frequently attributed to human error. However human is liable to error. To exclude human factor from a huge system...

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...

Towards Improved Loading Model for Design of Offshore Structures
The study presented in this paper uses geometries of different offshore platforms to quantify the effects of uncertainties in design calculations. The effect of wave directionality and...

Seismic Hazard Estimation in the Eastern U.S.
Probable seismic hazard is generally estimated considering five elements: 1) seismicity; 2) source radiation; 3) wave propagation (attenuation); 4) site response; and 5) ground failure....

Response Modification Factors for Buildings and Bridges
Response Modification Factors (RMF) are often used for the seismic design and the safety evaluation of buildings and bridges. The advantage of using RMF is to account for the nonlinear...

A Seismic PRA Procedure in Japan and its Application to a Building Perforance Safety Estimation: Part 1. Seismic Hazard Analysis
A method for seismic hazard evaluation which deals with response spectrum information is presented. A local city near Tokyo facing the Pacific Ocean is selected for the case study. It...

A Seismic PRA Procedure in Japan and its Application to a Building Performance Safety Estimation: Part 3. Estimation of Building and Equipment Performance Safety
This paper presents an application of a seismic PRA procedure to an apartment building, which also contains an electric substation for the surrounding area. In this procedure, as presented...

Safety Improvement of Earthquake Loaded Structures Application of Semi-Active Control in Multi-Storey Buildings
This paper presents the studies for development of a new concept of aseismic design of structures. Basis of that engineering will be a structural optimization including elastic supported...

A Geophysical Model for Earthquake Hazard Estimation
A method for site hazard estimation from subduction earthquake is developed by combining a time-dependent earthquake occurrence model and a ground motion model into a unified hazard model....

Assessment of Component Safety Due to Common Cause Events
This paper demonstrates the use of Modified Fault Tree Analysis (MFTA) and Modus Tollens Deduction (MTD) techniques for assessing the safety of redundant components due to common cause...

Safety Assessment Methodology for Construction Operations
There are many factors that affect the safety of construction operations which might lead to failures and accidents. The factors are associated with random, human-based or system uncertainty....

Assessment of Safety of Existing Buildings Using Fuzzy Set Theory
In this paper, an approach to estimate structural safety which may serve as a bridge between the theoretical and empirical approaches is explored. The new method combines subjective judgment...

Application of Probabilistic Methods in Construction Industry
Recent attempts for theoretical development and engineering application of probabilistic methods, which have been carried out in a Japanese engineering and construction company, are summarized....

The Extreme Value Distribution of Non-Stationary Vector Processes
In this paper the extreme value distribution of functions of non-stationary vector processes is studied. For these processes asymptotic approximations for the crossing rates through hypersurfaces...
