Endochronic Constitutive Modeling of Frozen Soil
The static behavior of a permafrost type foundation, for a typical artificial island in the Arctic, is determined using endochronic axisymmetric finite element analysis. Endochronic constants...
Constitutive Equations for Ice as a Damaging Material
Constitutive equations for ice subjected to uniaxial compression are developed based on applications of the theory of continuous damage mechanics. A physical model of ice deformation response...
Composite Columns?Design and Examples for Construction
The new German standard DIN 18806, part 1 gives the rules for the design of composite columns. The general method, taking into account all the inhomogeneties of the two materials steel...
Estimating Delays at Navigation Locks
Tow delay is an important component of cost at navigation locks, and delay reduction is a major benefit of lock improvement. Computer simulation is a valuable method of estimating lock...
Quantifying the Exposure
Methods of categorizing and modeling of exposure will be presented. The use of modeling for the estimation of population exposure will also be examined and some errors inherent with such...
Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...
A Methodology for Forecasting APM Operation and Maintenance Trends Using Existing Experience
Operation and Maintenance responsibility for the Morgantown, West Virginia Automated People Mover (APM) was assumed by West Virginia University some nine years ago. The experience of the...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
Beam Analogy for Vertical Curves
The vertical curve is analyzed as a moment diagram for a uniformly loaded single beam with a concentrated moment at one end. This contributes some flexibility in approach, and enhances...
Using Learning Curves in Terminations for Convenience
Curved Sewers: Yes or No?
A study of curved sewer use in Southern California examines sewer design and maintenance of curved versus straight sewers. A telephone survey of personnel in design and maintenance of...

Viaduct
This concrete box girder viaduct, an Award of Merit in the 1984 Outstanding Civil Engineering Achievement competition, helps complete a seven mile gap in the Blue Ridge Parkway in North...
Strength and Stiffness Characteristics of Steel Ladder-Type Cable Trays
Ladder-type cable trays identical with the as-built are generally tested to establish their strength and stiffness characteristics. Test data for systems in operating plants, however,...
Snowmelt Runoff Models for Water Supply Forecasting
Remote sensing is changing the approach in snowmelt runoff modelling. Instead of a simulated snow cover, the areal extent of the real snow cover can be periodically evaluated. Adaptation...
