The Concept of the New Waterway Storm Surge Barrier: Reliability as an Integral Part of a Nation's Sea Water Defense System
In the southwest of the Netherlands a storm surge barrier is to be built in the waterway that gives access to the port of Rotterdam. Strict design conditions ensure that only very slight...
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....

A new statistical procedure is proposed for the estimation of maximum earthquake magnitude M in intraplate regions. Starting from a historical catalog of events and a seismotectonic classification...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...

This paper presents an automated damage-controlled design method, which aims for uniform damage distribution throughout the entire building frame while respecting the strong-column weak-beam...
Simple Damage Predictors for Large-Scale Seismic Risk Mapping
Although it is now recognized that there is a risk of moderate seismic activity in the Eastern United States, many existing buildings were not designed for earthquake forces. To evaluate...
Seismic Fragility Analysis of Shear Wall Structures
This paper presents an analytical method to generate seismic fragility curves for shear wall structures. Uncertainties in earthquake motion and structure are quantified by evaluating uncertainties...
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...
Seismic Response of Structures and Reliability Design
This paper develops a modified SRSS Method which allows a designer to select the reliability that he wishes to realize in each of the various elements of a given structure subjected to...
Wind Vs. Seismic Design
