GEER Response to the Oso Landslide: Documenting Perishable Details Helps Turn Disaster into Knowledge
Two months after the disastrous March 22, 2014 landslide near Oso, Washington, GEER representatives visited the affected area to gather data. This article is based on the report generated...
Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...
Adapt to Dynamic Conditions and Practice
This chapter discusses the fourth guiding principle for critical infrastructure: adapt critical infrastructure in response to dynamic conditions and practice....
Breakwaters '99
First International Symposium on Monitoring of Breakwaters
The papers present state-of-art methods and technologies that are used in the structural and environmental monitoring of rubble mound breakwaters. Structural monitoring concerns the structural...
New Parameters to Model Ground Motions
The paper presents three new parameters to characterize earthquake-induced ground motions. All three parameters evolve from the concept of response spectra, and are termed 3D response...
Dynamic Response of Lattice Towers and Guyed Masts
Prepared by the Task Committee on the Dynamic Response of Lattice Towers of the Technical Committee on Special Structures and the Technical Administrative Committee on Metals of the Structural...
Origin of US&R Task Force
This chapter reviews the federal agencies that were used for rescue and recovery efforts....
Efficient Pump Representation for Fixed-Grid MOC in Pipeline Systems
An explicit solution of the pump power failure boundary condition is shown to have many computational advantages over the conventional implicit pump boundary condition solution (i.e.,...
Overview of Drought Response Strategies
An overview of drought response strategies in the United States is presented. The paper focuses on tactical strategies for mitigating the impacts of drought conditions. A general structure...
A Comparative Study of the Transformed Methods for Solving Richards' Equation
The Richards' equation represents the movement of water in both saturated and unsaturated porous medium. The numerical solution to this equation is difficult because the algebraic...
A Comparison of Sediment Routing Models
In this paper the authors have compared the performance of coupled linear and non-linear methods of solution from these generic types, in order to assess their suitability for use in optimisation...
Derivation of New Dispersion Coefficient Equation for Natural Streams
A new simple method for predicting dispersion coefficient by using hydraulic and geometric data easily obtained in natural streams has been developed. Dimensional analysis was implemented...
Nonlinear Analysis of Stiffened Laminated Cylindrical Shells Using the Layerwise Theory of Reddy
The layerwise shell theory of Reddy is used to develop the buckling and the postbuckling equations of circular cylindrical shells reinforced by means of axial and ring stiffeners and subject...
Large Deformation Theory Using Truncated Rotations
Today's aerospace industry has advanced to the point of using optimum design techniques in virtually all applications. In structural elements, orthotropic fiber composite materials have...
Debating Steel - Connection Design
The debate about responsibility for structural-steel-connection design is among the hottest engineering disputes of our generation. Meetings have been held on the subject, articles written...
Discontinuous Control of Seismic-Excited Nonlinear and Hysteretic Structures
Based on the theory of variable structure system (VSS) or sliding mode control (SMC), discontinuous control methods are presented for application to seismic-excited nonlinear civil engineering...
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...
Design of Box Girder Bridges by Nonlinear Theory
A modified design procedure applicable to a large number of conventional box girder bridges with longitudinally-stiffened flanges has been presented in this paper. It determines the ultimate...
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...
