Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Review of Composite Analysis Methods for High Temperature Applications
This paper addresses a number of unique problems encountered in the stress analysis of high temperature composite materials. The materials used as structures subjected to temperatures...
Fatigue and Fracture Evaluation of Riveted Bridge Members
Among the major concerns of bridge engineers today are the fatigue damages that have been accumulated in riveted members and the safety of riveted structures. Many of these structures...
A Method of Computing Impact and Fatigue Life in the Railway Steel Girder Bridge
The purpose of this paper is to investigate the dynamic interactions between an steel girder bridge and a moving freight train. A non-linear, 100-ton, freight car vehicle model and a 70-ft...
Fatigue Behavior of Steel Connection Angles
A method for predicting the fatigue behavior of flange angle elements is presented. The primary emphasis herein concerns an analytical approach for evaluating the fatigue life of flange...
Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...
NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...
Service Life of Underground Concrete Structures
The service life of underground concrete depends on both the physicochemical properties of the concrete materials and the properties of the in-service environment. The major factors controlling...
Evaluation and Remediation of Construction Defects in Tilt Wall Panels
Both the surface appearance and structural safety were of concern to the Owner of a five year old warehouse structure that was experiencing delamination of tilt-up wall panels. Delamination...
Seismic Resistant Low-Cost Masonry Buildings in Peru
Future housing in developing countries will be provided mainly in medium rise, four to six stories, bearing wall masonry buildings. This paper reports on the rationality behind this political...
A Summary and Review of Fatigue Data for Mechanical and Welded Splices in Reinforcing Bars
Published reports pertaining to fatigue tests of welded and mechanical splices in reinforcing bars were reviewed. It was observed that most specimens fractured in the reinforcing bar adjacent...
Fatigue Strength of Welded Steel Mesh
Welded steel mesh (WSM) is prefabricated by welding cold-drawn wires in a grid-like mesh. Engineers avoid using WSM as main reinforcement in highway structures due to their lack of knowledge...
The Fatigue Performance of Welded Joints in a Marine Environment
The fatigue lives of plate-plate, pipe-plate, and tubular welded joints tested in seawater under free corrosion, optimum cathodic protection and cathodic overprotection measured in the...
Inspection Strategies for Offshore Structures
The fatigue limit state is the governing limit state for the structural dimensions in several parts of offshore structures. Prediction of the fatigue life of tubular joints and other welded...
Effect of High Frequency Response on Fatigue of Offshore Structures
Welded steel specimens have been tested under several loading spectra to determine the effect on fatigue life of high frequency components in the psd of the stress or strain in the joint....
Low-Cycle Fatigue Reliability of Offshore Structures Subjected to Earthquakes
This paper develops and implements a methodology for predicting probabilistically the damage an offshore structure will experience in an earthquake. The analysis begins with the probability...
Concrete Strength-Quality Assurance
The usual criterion for establishing grades of structural concrete is the compressive strength measured in an arbitrary manner on a standardized specimen stored in a stipulated fashion...
Development of High Strength Composite Cables
Fiber reinforced composite materials offer significant advantages over conventional materials, for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages...
Long-Term Buckling of Composite Columns
A consistent theoretical study of the creep buckling behaviour of viscoelastic laminated columns is presented. The problem is treated by means of the quasi-elastic method. The analysis...
