A Multilayered Model for Analysis of Composite Pipes
A multilayered model is developed to analyze the behavior of composite pipes, such as prestressed concrete pipe, to the combined effects of internal pressure and applied loads. The pipe...
An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
Cables in Trouble
Having inspected more than half of the world's cable stayed bridges, the authors conclude that many are in danger of sudden collapse unless corrosion problems can be stopped....
The Heavy Duty Geogrid Wall
The geogrid reinforced soil retaining wall was a key component in reconstructing a small hydroelectric plant situated at the center of Cascade Dam in Michigan. It was necessary that the...
New Pavement Materials
New materials and construction techniques are constantly being evaluated to extend pavement life and to improve overall performance of highway and airfield pavements. To be beneficial,...
Methods for Determining Actual Evapotranspiration in Plots
The major methods used at INRA since 1965 for determining actual evapotranspiration (AET) in plots are reviewed in this paper. These procedures involve either direct determination (weighing...
Active Control of Flexural Vibrations in Beams
The feasibility of using piezoelectric actuators to control the flexural oscillations of large structures in space is investigated. Flexural oscillations are excited by implusive loads...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Repairing and Strengthening of Reinforced Concrete Buildings Damaged in the 1985 Mexico City Earthquake
This paper describes briefly the criteria and techniques used for the repairing and strengthening of reinforced concrete buildings damaged in Mexico City during the 1985 earthquakes. It...
Design and Performance Monitoring of Clay-Lined Landfills
The use of thick clay liners has been applied to Wisconsin landfills for over a decade. Currently, there are over 35 solid waste disposal facilities in Wisconsin which have been constructed...
Geotechnical Properties and Landfill Disposal of FGD Sludge
Extensive test data from more than a decade of research are compiled on the geotechnical engineering properties of flue gas desulfurization (FGD) sludges with emphasis on double alkali...
Effects of Damage and Redundancy on Structural Performance
There are numerous factors involved in the interrelationship between damage states, redundancy, system strength and structural performance. This volume examines some of these factors and...
LFRD Bridge Design as Viewed by the Designer
The load and resistance factor design (LFRD) design concept has been resisted by some bridge engineers on the grounds that it represents a reduction of the 'factor of safety'...
The Behavior of R/C Pinned Bridge Columns under Lateral Loading
Four one-eighth scale one-way hinge details of the type used in highway bridges were tested to study the effect of combined shear and flexure caused by lateral loads. The aspect ratio...
Local Buckling and Cyclic Behavior of Tubular Members
The effect of the local buckling is included in the cyclic analysis of tubular members. The cyclic moment-curvature curves are obtained numerically. Three types of closed form expressions...
Anchorage Forces for Z-Purlin Supported Standing Seam Roof Systems
This paper presents the results of a limited study to determine if the provisions of Section D. 3. 2. 1 'Anchorage Bracing for Roof Systems Under Load with Top Flange Connected...
Bending Strength of Thin Cold-Formed Steel Straight Panels
An experimental investigation on the bending strength of 26 gage cold-formed corrugated steel straight panels with web-depth to thickness (h/t) ratio of 475 is presented. A typical test...
Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
