Beam Web Shear Connections: An Experimental Study
Bolted shear web connections were tested to evaluate the 1978 AISC Specification provisions concerning edge distance, end distance, and bearing stresses. Tests wee performed on beams with...

Beams Under Lateral Projectile Impact
The influence of transverse shear effects, rotary inertia and the boundary conditions on the dynamic behavior of rigid perfectly plastic beams subjected to projectile impact at midspan...

Response of Taut Strip Models to Turbulent Wind
An experimental investigation was conducted to clarify the fundamental behaviour of the proposed taut strip wind tunnel model of long span bridge deck systems. The study shows that this...

DO Model for Discharges from Deep Impoundments
A simple model is presented for the annual dissolved oxygen (DO) cycle of releases from the hypolimnion of deep impoundments. The model includes mathematical formulations and rate constants...

Dynamic Response of Plate on Elastic Half-Space
Analytical results are presented for the dynamic response of a plate bearing on an elastic half-space and subjected to harmonic forces. The present work represents a departure from existing...

Plates of Varying Thickness with Four Simply Supported Edges
The methods of double finite Fourier transformation and two Trancendental Functions, Six and Cix, are adopted. A general expression of solution is given for a thin plate of variable thickness...

Urban Impacts of Water Supply Reservoir
Water quality of Lake Houston, a rapidly urbanizing water supply reservoir near Houston, Texas, was characterized in terms of sediments, nutrients, and algal population. Data was collected...

Wave Spectrum Changes on Sloped Beach
A comparison of all the different approaches to analyze the problem of wave spectrum change on a sloped beach is presented. It is shown how the heuristic, theoretical and numerical formulations...

Task Committee on Engineering Education: Report to the Board of Direction
Engineering education, not civil engineering education alone, is in a crisis which could seriously damage the engineering profession and the national interest. Too few graduates are earning...

Asymptotic Solution for Dam-Break Problem
The kinematic wave approximation is used to obtain a simple, closed-form solution for the catastrophic failure of a dam upon a dry, sloping channel. The solution validity is investigated...

Safety Factor of Dams and Retaining Walls
Whatever the definition of the safety factor against overturning of dams and retaining walls, the state of minimum stability occurs when there is some water present in front of the wall....

Calorific Value of Wastewater Plant Sludges
Calorific values of wastewater plant sludges are best determined using an oxygen bomb calorimeter, an apparatus which is not readily available in many plants. Using a variety of sludges...

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...

Prediction of Water Level in Tidal Inlet
A very important and difficult problem is operation of gates at the inlet of tidal lakes in order to control water quality and quantity. The gate operation must sufficiently satisfy both...

Slipforming of Reinforced Concrete Shield Building
The unique design and construction features of slipforming the heavily reinforced concrete cylindrical shield walls at the Satsop nuclear plant site are presented. It proved that, with...

Technical Aspects of Metric Construction
The Water and Power Resources Service, formerly the Bureau of Reclamation, has begun construction of a number of major projects using SI metric units. Technical aspects of the design and...

Construction Operation and Microcomputers
The availability of small reasonably priced computers—micro-computers—has made computer based techniques and management control accessible for the analysis of construction processes. A...

Scheduling: Effective Methods and Techniques
Network planning and analysis (CPM) is a proven means to outline the many activities to be performed and to investigate the feasibility of a given construction project. Commencing with...

Planning, Scheduling, and Communicating on Crew Productivity
Construction project planning and scheduling along with communication of the plan have major impact on the productivity of field crews. Though the size of the impact is practically impossible...

Underground Transit Station Construction in Japan
Technologies used in Japan for constructing underground stations for heavy-rail urban rapid transit systems are described. Two example projects have been chosen that illustrate different...
