Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...
Timber Pile Length Determination Using a Nondestructive Technique
Determining timber pile length is critical when evaluating the potential effects of scour and for determining pile capacity. Unfortunately, records of timber pile lengths are typically...
Structural Analysis of Pavements: State-of-the-Art
This paper presents the state of the art of the structural analysis of pavements, using high-speed computers. The numerical models include layered analysis and finite-element and finite-difference...
Biaxial Testing of Brittle Repair Material for Rigid Pavements
Most codes of practice prescribe procedures for selecting patch configuration and material based on test devised for evaluating new pavement materials. This study is aimed at examined...
Fires Deemed to Have Tested Structural Performance
This paper provides an overview and progress report of a survey and study of fire incidents deemed to have tested the structural performance of large buildings. This ongoing effort was...
Consequential Fire Loads on Structures
Much less consideration has been given to the performance of modern structural and architectural systems during fires and to the minimization of damage that threatens the integrity of...
Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...
Seismic Fragility Analysis of Sheahan Pumping Building
This paper presents a seismic fragility analysis of the Sheahan pumping building located in Memphis, Tennessee. In the analysis, seismic response is determined from the response spectrum...
Estimation of Structural Damping of Buildings
The full-scale data on damping ratio are collected from 77 buildings within Japan. Almost all data are obtained from vibrations with a very small amplitude such as microtremor, man-power...
Earthquake Barrier Technology: Sliding-Friction Energy Dissipation
The first project in America to use friction damping was approved by the City of Los Angeles for the retrofit of a 10-story concrete frame building, designed to resist a Maximum Credible...
Cyclical Behavior of Welded Steel Shear Studs
Four specimens of composite steel and concrete beams were experimentally tested to obtain the cyclical behavior of the welded steel shear stud. This information may be used for the analysis...
AISI-FHWA Model Bridge Test
The Model Bridge Study involved a large experimental test program to evaluate the behavior of a 0.4-scale model of a two-span continuous plate-girder bridge with modular precast prestressed...
Horizontally Curved Steel Bridge Research-Update 2
Theory and data necessary for the development and calibration of an LRFD based curved steel bridge specification do not presently exist. To address these needs, the Federal Highway Administration...
Current and Future Research in Steel Bridge Structures
The topics I have listed are ones which I am aware through discussions with various researches, designers, and industry representatives. The list of topics is presented as a starting point...
Pre-Engineered Short Span Steel Bridges
The American Iron and Steel Institute has developed a package to aid in expediting the design of short-span steel bridges for use by owners, designers, fabricators, and contractors in...
Time-Dependent Load-Distribution Behavior of Parallel-Member Wood Systems
The effect of differential member creep on the load-distribution behavior of parallel-member wood systems is examined. Variability in the creep response of the individual component members...
Compressive Strength of Masonry Prisms
Many factors affect the estimation of compressive capacity of a masonry prism. In the study the effects due to grout strength, mortar joints, block geometry and size, moisture content,...
3-D Dynamic Analysis of the Brent-Spence Through-Truss Bridge
A three dimensional finite element model is developed for the free vibration analysis of main bridge. The model was calibrated by comparing the free vibration analysis results with ambient...
Condition Assessment of Highway Bridges
An application of modal testing and structural identification in the condition assessment of bridges is presented. Damage definition and conceptualization is discussed. Damage detection...
Cyclic Behavior of Joints Between Steel Beams and Reinforced Concrete Columns
The design and behavior of composite beam-column joints for seismic design are reviewed based on the results of tests. Issues addressed include the strength, deformation, and toughness...
