Fatigue of Two Year Weathered A588 Stiffeners and Attachments
An experimental program examined the effect of A588 steel specimens with transverse stiffeners and attachments. It was found that two years of continuous weathering, prior to stress cycling to failure,...

Densification of Paper Mill Sludge Materials
Dewatered paper industry primary sludges have a consistency similar to very soft remolded clays. Densification involves removal of additional water, usually by placement of a surcharge load after deposition...

Fatigue Reliability: Quality Assurance and Maintainability
Periodic reevaluation of a structure by inspection and proof loading with repair when needed is an alternative to complete dependence on initial quality for obtaining structural reliability. The theory...

Fatigue Reliability: Introduction
A four-part state of the art summary on fatigue reliability is presented by the ASCE Committee on Fatigue and Fracture Reliability. This first part reviews fatigue models commonly used by designers, e.g.,...

Approximate sizing of Reservoirs for Detention Time
To meet the detention time requirements of the Office of Surface Mining, sediment control reservoirs must be sized to give a certain detention time, as defined by the time difference between the center...

Simulation Approach to Assess Highway Performance
A procedure is presented that can be utilized to estimate the impacts of alternative financing policies and other highway related factors on future highway system performance. The approach is to first...

Spectrum of Shallow Water Waves
A complete and coherent formulation for defining different spectral shallow water wave bands is stated. It takes into account the attenuation and dispersion characteristics of the waves and the predominant...

New Flat Plate Turbulent Velocity Profiles
A new, simple equation describing the turbulent velocity profile over flat plates is developed by using the control volume statements of mass and momentum conservation. This expression accurately gives...

CW Microwave Location of Voids Beneath Paved Areas
The problem of locating voids beneath paved areas is a perplexing and costly one. Usually voids are investigated by test borings, which is a discontinuous hit-or-miss process. The use of a continuous nondestructive...

Incipient Motion of Sand Particles on Side Slopes
Several criteria have been theoretically proposed for the critical shear stress of noncohesive sediment on side slopes. However, no laboratory work has ever been done on this problem. A theoretical study...

Dispersion in Three Dimensions: Approximate Analytic Solutions
Solutions to three-dimensional convection dispersion equation under different boundary conditions are obtained by integrating the appropriate Green's functions. Two approximations are used during the integration....

Fatigue Reliability: Development of Criteria for Design
This is the fourth in a series of four articles prepared by the ASCE Committee on Fatigue and Fracture Reliability. This paper summarizes how criteria for assuring integrity against fatigue and fracture...

El Infiernillo and La Villita Dams: Seismic Behavior
El Infiernillo and La Villita rockfill dams in Southern Mexico underwent an earthquake of magnitude 7.6 (Ricter) on March 14, 1979, with epicenter about 68 mi(110 km) from each dam. As a consequence measurable...

Alongwind Response Estimation: Closed Form Solution
The problem of dynamic alongwind response of structures to forces induced by atmospheric turbulence is treated in this paper. Starting from the classical formulation, the study analyses the behaviour of...

Full-Depth and Granular Base Course Design for Frost Areas
When properly designed and constructed, the Asphalt Institute full-depth pavement concept can be a viable design alternative for seasonal frost areas. The Corps of Engineers reduced subgrade strength frost...

Obtaining the Layout of Water Distribution Systems
An essential first step in the design of a municipal water distribution system is the determination of the locational placement or layout of the links of pipe that will form the system. A two-level hierarchically...

Estimating Culvert Scour in Cohesive Material
An investigation of scour at culvert outlets in a cohesive bed material is presented. Twelve experiments of 1000 minutes duration were conducted using a cohesive bed material. Culvert 27.3 cm (10-in.),...

Compression of Free-Ends During Triaxial Testing
When lubricated platens (free-ends) are used to load particulate media there is an associated error in any measured axial deformation due to compression and distortion of the rubber/grease layer. This...

Structural Response of Skew RC Box Girder Bridge
Analytical and experimental results obtained in a study of a large-scale 45° skew two span four cell reinforced concrete box girder bridge model are presented. The model, which was a 1:2.82 scale replica...

Ultimate Strength of Skew RC Box Girder Bridge
Analytical and experimental results obtained in a study of a large-scale 45° skew two span four cell reinforced concrete box girder bridge model are presented. The model, which was a 1:2.82 scale replica...
