Statistical Response of a Class of Hysteretic Systems
The response of a hysteretic nonlinear system subjected to a filtered white noise is considered. The method of time-dependent equivalent linearization is used and the moment equations...

Seismic Fragility Analysis of Sheahan Pumping Building
This paper presents a seismic fragility analysis of the Sheahan pumping building located in Memphis, Tennessee. In the analysis, seismic response is determined from the response spectrum...

Estimation of Structural Damping of Buildings
The full-scale data on damping ratio are collected from 77 buildings within Japan. Almost all data are obtained from vibrations with a very small amplitude such as microtremor, man-power...

Response Study of a Flexible Building Using Three Earthquake Records
This paper examines the response of a flexible building during three earthquakes. The records from the building are long and contain low frequencies. The site frequency (0.33-0.38 Hz)...

Laser Generation and Detection of Ultrasound in Concrete
Laser ultrasonics is a non-contact nondestructive evaluation method that uses lasers to generate and detect elastic waves. In this work, laser ultrasonics is used to produce broadband...

Sensors and Techniques for Structural Monitoring
This paper summarizes measurement requirements for the monitoring of engineering structures and describes new sensor/system configurations that are finding useful application in field...

Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...

Impact of Non-Gaussian pdf on Reliability Estimates for Deep Water Platforms
The offshore community has invested a great deal in the analysis and design of compliant deep water platforms such as tension leg platforms (TLPs) and more recently spar platforms. Tension...

Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...

Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...

Nonlinear Buckling Response of Single Layer Latticed Barrel Vaults
Elastic overall buckling of single layer latticed barrel vault roof structures under static vertical loading is investigated using a fully nonlinear finite element solution procedure and...

Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...

Applicability of Pseudo-force method to Highly Nonlinear Dynamic Problems
This paper deals with solution of nonlinear dynamic problems using Pseudo-force method. A solution algorithm involving Pseudo-force method is presented. The objective is to investigate...

Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...

Validation of a Continental-Scale Storm Surge Model for the Coast of Delaware
Coastal structures are designed to provide protection against various forces of nature acting in the coastal zone. Structures such as seawalls are expected to provide onshore protection...

Homogeneity Tests Based Upon Gumbel Distribution
This paper analyzes the performance of three homogeneity tests for Gumbel distributed flood flows. The classic Dalrymple test, a method-of-moment Cv test, and a normalized-quantile test...

Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....

An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...

Risk-Based Analysis for Flood Damage Reduction
The traditional approach of the U.S. Army Corps of Engineers to flood damage reduction studies is compared to risk-based analysis, a method of performing studies in which uncertainty in...

Quantifying Flood Damage Uncertainty
The U.S. Army Corps of Engineers (Corps) has adopted a risk-based analysis procedure to analyze the effect of uncertainty on flood damages and the benefits of flood damage reduction projects....
