Tests of Composite Beams with Web Openings
An experimental investigation to study composite beams with rectangular web openings is presented. Six composite beams and one steel beam were tested. W14 × 34, W18 × 45 and W18 × 46 sections...

Fatigue Reliability: Variable Amplitude Loading
Models which designers use to predict fatigue under variable amplitude and random loading are summarized. Basic terminology associated with random process theory is presented. Models for...

Trends in Engineer Registration, Sunset Review: How to survive?
Thirty-one states have legislated periodic review of licensing and regulatory functions, including professional registration or licensure of engineers, land surveyors, and related professionals,...

Regulation of Engineers in California
State-administered certification programs for the engineering profession are unjustified and should be eliminated. The reasons for this conclusion have nothing to do with the peculiarities...

Sand Liquefaction: Inelastic Effective Stress Model
An effective stress numerical model for soil liquefaction, which provides interaction between shearing deformation and transient pore-water pressure development, is presented. Some attractive...

Welded and Bolted Beam-to-Column Connections
For many years research on welded and bolted beam-to-column connections has been carried out in The Netherlands, with particular emphasis on those connections which cannot transmit the...

Pressure Distribution Design for Septic Tank Systems
Pressure distribution of septic tank effluent in subsurface soil absorption systems is gaining in popularity. This method of effluent distribution has the advantage over other methods...

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,...

Large Deflections of Beams with Combined Loads
Closed-form solutions are presented for the problem of large deflection of a cantilever beam with a couple and a concentrated load acting simultaneously at the free end. Dimensionless...

Creep of Pipes Under Axial Force and Bending Moment
The load-deformational behaviour of a thin-walled circular cylinder in the presence of axial force is studied. Based on the small deformation theory, an exact analysis is presented for...

Stresses on Rapidly Sheared Fluid-Solid Mixtures
Constitutive equations were derived describing the stress in a rapidly sheared mixture of granular cohesionless solids and a Newtonian fluid. These equations are considered to describe...

Finite Element Method for Interface Problems
A method for incorporating interface discontinuities in a finite element analysis of discontinuous media is presented. For computational purposes the procedure is implemented into the...

Short Line Change Estimates Neat Oarai, Japan
To estimate the shoreline changes near the Port of Oarai when the groin was built, the field observations were done and the characteristics of the coast were investigated. A present shoreline...

Ultimate Strength of Gapped Joints in RHS Trusses
A theoretical and empirical analysis is presented for the ultimate static strength of gapped joints in welded Rectangular Hollow Section trusses having one compression bracing member and...

Nature of Wave Attenuation in Open Channel Flow
The identification of the term or group of terms which will cause a free-surface flow to dissipate is investigated. It is shown that wave attenuation is caused by the interaction of the...

Node Factor Variations and Joint Occurences
In constructing exceedance frequency distributions for extremal heights resulting from joint occurrences of tsunamis or storm surges and the astronomical tide, a period of time for the...

Seismic Behavior of Moment Connections and Joints
The behavior of moment connections and beam-column joints in moment resisting steel frames subjected to severe earthquakes is studied. The cyclic inelastic deformation capacities of different...

Evaluation of Selected Initial Dilution Models
A number of mathematical and computer models are currently available to calculate initial dilution of treated wastewater effluent discharges into the ocean. This paper presents a comparative...

Columns with Semirigid Joints
The influence of realistic semi-rigid end restraint on the strength and behaviour of real steel columns is investigated. An analytical procedure is developed which includes the effects...

Photosynthesis-Light Mathematical Formulations
Photosynthesis-light curves for photoplankton describe the characteristic dependence of the instantaneous rate of photosynthesis on incident light. Six different mathematical formulations...
