Creep of Pipes Under Axial Force and Twisting Moment
The load-deformational behavior of twisting of pipes in the presence of axial force is examined. Based on the small deformation theory, charts and curves, which relate the twisting moment,...
Laterally Loaded Pile Behavior
An analysis of laterally loaded piles is presented in which the pile is treated as an elastic beam supported on non-linear, shear coupled, horizontal springs. The edge forces which act...
Drainage Systems for Land Treatment of Wastewater
Simulation methods for design and evaluation of drainage systems for wastewater land treatment sites are presented. The methods are based on the water management model, DRAINMOD, for describing...
Models of Alfalfa Yield and Evapotranspiration
Data of per-cutting yields and annual yields from four cuttings were collected over six consecutive years for alfalfa grown on three lysimeters. Corresponding evapotranspiration was obtained...
Discharge Assessment in Compound Channel Flow
A series of laboratory tests were performed to measure the boundary shear stresses in a compound channel consisting of a main channel and associated shallow floodplains. Four different...
Use of Cyclic Element Tests to Assess Scale Models
Large scale laboratory model tests have been performed to aid the design of offshore gravity platforms. The paper shows that undrained conditions, necessary for correct model simulation,...
Separation Angle Effect on Vortex Shedding Frequency
Vortex shedding frequencies were measured for a number of two-dimensional bluff bodies whose boundary layers separation angles ranged from 0°-90° to the oncoming flow. Strouhal numbers...
General Contractor Project Control Practices and MIS
Building contractor project control, information documentation, flow practices, and the attributes of project management personnel provide the focus for this paper. The methodology employed...
Foreman-Delay Surveys: Work Sampling and Output
The usefulness of foreman-delay surveys (FDS) for performance measurement and productivity improvement at construction sites is evaluated by comparison with production rates and work sampling...
Tension Stiffening Concept Based on Bond Slip
Consideration of tension stiffening in reinforced concrete panels by means of so-called tension stiffening factors, appearing in total and incremental equilibrium equations, has proved...
Serviceability Limit States: Connection Slip
The serviceability limit state for slip of bolted steel joints is the slip-resistance. The statistical properties of the parameters which define this resistance are presented and analyzed....
Load Transfer Mechanisms in Piles and Pile Groups
This paper describes patterns of measured load transfer in a full-sized instrumented pile group; subgroups within the main group; and in single control piles loaded in compression. The...
Fluctuating Wind Loads on Buildings
A method for evaluating the fluctuating wind forces and their distribution on buildings has been developed and applied to the understanding and quantification of crosswind loads on a square...
Integrated Control of Combined Sewer Regulators
Integrated operation was simulated of 10 dynamic combined sewer regulators on a Montreal interceptor. Generally, when no in-line or other in-system storage can be called upon, advantage...
Coastal Pollution from Septic Tank Drainfields
Wet weather and dry weather sampling is utilized to monitor densities of coliform bacteria in waters draining residential areas of coastal North Carolina. The bacterial levels are compared...
Inflation and the Construction Industry
Inflation has become a chronic problem whose effects permeate the entire construction industry. Owners are not only paying for the increased costs of facilities and capital but also for...
Bid Markup Calculation by Crew-Day Method
A method for the calculation of bid markup to be used by contractors is developed which relates to the capacity of a firm during a given time period and to its particular financial goals....
Flexural Strength of Flat Slabs at Exterior Columns
The flexural strength of exterior panels of flat slab structures is investigated by use of Yield Line Theory. Six controlling, geometrically admissible, collapse mechanisms are identified,...
Circular Voided Concrete Slab Stiffnesses
Finite element procedures for determining the plate bending stiffnesses of a circular voided slab are presented and the results are compared with those obtained from tests on model elastic...
Celerity of Transient Bed Profiles
The applicability of a formula for the calculation of celerity of alluvial channel bed transients has been verified using data from flume experiments. The formula is easy to use; the celerity...
