Strength of Composite Beams at Web Openings
A model for the strength of steel-concrete composite beams with unreinforced, rectangular web openings is presented. The model includes the contribution of the concrete slab to shear strength,...

Full-Scale Tests on Ground Anchors in Fine Sand
A series of ground anchors of varying lengths were installed in a medium dense sand, with a veiw to study as many as possible of the variables influencing anchor behaviour and load transfer....

Post-Buckling of Plates in Compression and Bending
The elastic post-buckling behavior of rectangular plates in combined compression and bending is presented. The theoretical investigation begins with the Marguerre's compatibility...

Evaluation of Environmental Assessment Methods
Twelve representative methods for environmental assessment are described, evaluated, and compared in terms the following seven evaluation criteria: treatment of the probabilistic nature...

Multipurpose Land Information Systems: A Canadian Perspective
The growing involvement of the state in the land management process has been accompanied by the increasing presence and influence of professional managers and formal planning processes....

Generalized Wave Equation in Finite Domains
A generalized equation governing one dimensional wave propagation in finite domains is solved by employing the finite Sturm-Liouville transform. The formulation includes the effects of...

Bridge Loading: Research Needed
The need for research in areas of bridge loading is examined. It is argued that one reason research is incomplete is poor definition of the requirements. The main priorities for research...

Computers in Civil Engineering Practice
The current use of computers in civil engineering is discussed. Engineers' expectations from computer use are outlined and realistic considerations are presented. Advantages...

Reliability Analysis of Wood Transmission Poles
The feasibility of probability-based design procedures for electrical transmission lines is discussed. Single pole structures have been selected in this initial study because of their...

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,...

Vehicle Lateral Placements on Urban Roads
Time-lapse photographs were taken of traffic flows on five streets of varying lane width in the Toronto region. From these photographs, time histories of lateral placements and forward...

Remedial Treatment Exploration, Wolf Creek Dam, Ky.
After 15 years of apparently satisfactory operation, Wolf Creek Dam developed underseepage and piping problems associated with its karstic foundation. When a sinkhole developed at the...

Behavior of Type 2 Steel Frames
In the design of steel building frames, various simplifying assumptions are usually introduced when determining member design forces. Typically, the beams are assumed to be either rigidly...

Nonlinear Traveling-Wave Effects on Cooling Tower
The dynamic response of a tall reinforced-concrete hyperbolic cooling tower which has been designed for vertically incident seismic waves, based on a linear analysis, is examined for horizontally...

Lawsuits Arising Out of Reconstruction
Liability judgements resulting out of negligence in the performance of highway design, construction or maintenance activities have continued to increase in the past decade, notwithstanding...

Origin of Step-Pool Systems in Mountain Streams
Mountain streams very often present a step-pool aspect. Antidune formation alone; dispersion and sorting theory or velocity reversal as advocated for the origin of riffle-pool sequences...

Stormwater Pollution Control: Structural Measures
Combinations of storage and wet-weather treatment, integrated with dry-weather treatment facilities and nonstructural control measures on an area-wide basis, are found to provide the greatest...

Cracking at Openings in Prestressed Beams at Transfer
The behavior of prestressed concrete beams with rectangular openings is investigated at transfer. The theoretical analysis for the potentially-splitting stresses around the opening is...

Designing for Deficit Irrigation
Deficit irrigation is the practice of deliberately under-irrigating a crop. This practice may be preferable to full irrigation when water supplies are limited or irrigation costs are high....

Bed Load Fluctuation: Applications
Based on the distribution of transport rate, the fluctuation of bed load and its application to hydrological measurement have been studied. The variance and coefficient of variation of...
