Risk Analysis of Fatigue Failure of Highway Steel Bridges
Publisher: American Society of Civil Engineers
Abstract: A probabilistic fracture mechanics model was developed for determining the risk of fatigue failure of steel highway bridges. The model consists of: (1) stochastic inputs for crack growth rate, fracture toughness, initial ...
Nondestructive Strength Assessment of In-Place Wood Utility Poles
Publisher: American Society of Civil Engineers
Abstract: In-place nondestructive simulation evaluation of the remaining bending strength of wooden utility poles is vital to the continued and successful operation of the poles, viability of the electrical transmission and delivery ...
Combined Load Test and NDE: Novel Method to Diagnose and Load Rate Prestressed Concrete Girder Bridges with Serviceability Issues
Publisher: ASCE
Abstract: Vibration of highway bridges, although often ignored, is a serviceability issue that may contribute to concrete deck cracking and delamination. A recently constructed prestressed concrete bridge in the Dallas–Fort metroplex ...
Substitution of Fly Ash, Slag, and Chemical Admixtures in Concrete Mix Designs
Publisher: American Society of Civil Engineers
Abstract: The Florida Department of Transportation (FDOT) requires contractors for FDOT’s projects to submit a proposed concrete mix design prior to the production of any concrete. The contractor must use mix designs approved by ...
Effect of Pumping on Properties of Bridge Concrete
Publisher: American Society of Civil Engineers
Abstract: Pumping of concrete is widely used in large highway projects due to convenience and economy of placement. The short-term effects of pumping on the durability of concrete is well documented, whereas the long-term effects ...
Performance of Overburnt Distorted Bricks as Aggregates in Pavement Works
Publisher: American Society of Civil Engineers
Abstract: In the customary way of clay brick production by burning soil in Bangladesh and other developing countries, a good number of bricks (approximately 13%) are severely overburnt due to uncontrolled distribution of temperature ...
Modeling Compressive Strength Development in Florida Concrete
Publisher: American Society of Civil Engineers
Abstract: The Florida Department of Transportation (FDOT) specifications contain equations of concrete compressive strength to predict equivalent 28-day strengths based on core strengths at other times. The FDOT equations are many ...
Hurricane Mitigation of the Florida House Learning Center
Publisher: American Society of Civil Engineers
Abstract: The present study aims at investigating the applicability of the Florida Building Code (FBC) wind provisions and demonstrating benefits of the shuttering on the openings in the Florida House Learning Center, a unique ...
Contribution of Intermediate Diaphragms in Enhancing Precast Bridge Girder Performance
Publisher: American Society of Civil Engineers
Abstract: The objective of this study was to determine the effect of intermediate diaphragms on the stiffness of precast prestressed AASHTO type bridge girders, combined with the actual bearing stiffness and thermal changes. Some ...
Deficiency Analysis of Coastal Buildings toward Storm Damage Reduction
Publisher: American Society of Civil Engineers
Abstract: Engineering services provided by one of the writers to property owners, insurance companies, attorneys, and others have resulted in a compilation of case studies, based on more than 1,000 site inspections, suitable to ...
