Steel-Concrete Interaction by Means of Film Sensors
By adapting a recently-developed technique based on the piezoelectrical properties of relatively thick films made of Polyvinyldifluor organic composites and extensively used in robotics,...

Load Carrying Capacity of SPC Composite Column
This paper reports the result of beam column test of a new type composite columns. High-strength precast-concrete panels (hereafter denoted as PCa-panels) are fixed to the steel square...

Dynamic Response of Steel Fiber Reinforced Concrete
Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber...

Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...

Characterization of an ER Active Member
In the presence of strong electric fields (kV/mm), electrorheological (ER) materials change form viscous fluids to yielding materials. The class of ER materials used in this study have...

Advances in the Modelling of Long Span Bridges for Wind Effects
The continued development of longer span suspension and cable-stayed bridges has placed increased demand on both the designers and constructors of these structures for a better understanding...

Wind Effects and Countermeasures During Erection of a Cable-stayed Bridge
The cable-stayed bridge over the Karnali River in the Kingdom of Nepal was completed in 1992. Extensive wind tunnel testing indicated the likely wind response during construction. Several...

Wind Studies of the Owensboro Bridge, Kentucky
Wind tunnel studies on the Owensboro Bridge are described in this paper, including 1:50 scale sectional model tests and 1:160 scale aeroelastic model tests. Comparisons are presented and...

Fracture Analysis of Bolted Timber Connections
Application of fracture mechanics concepts to splice connections where bolts load timber members perpendicular to the grain is discussed. Attention is given to prediction of the load level...

Proposed Test Method for Determining Bending Yield Moment of Nails
Current engineering design procedures use a yield theory to establish the nominal resistance (capacity) for laterally-loaded nailed connections in engineered structures. In order to develop...

Validation of the European Yield Model for Nailed Connections
Recent changes in National Design Specification for Wood Construction (NDS) connection design methods make it necessary to validate the European yield model (EYM) for nails. Test values...

Special Considerations in the Design of Connections for Recycled Wood/Plastic Composite Lumber
There is current work in the American Society for Testing and Materials (ASTM) to evaluate potential test methods for what they refer to as 'commingled' plastic lumber. This category covers...

High-Strain Kinetic Testing of Deep Foundations
High-strain kinetic testing involves the upward decelerating or accelerating of a mass and using its inertial force to axial prolonged pulse at the head of a pile. Currently available...

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...

Some Aspects of Determination of Pile Capacity by the Wave Equation
This paper presents some new observations made during correlation study of pile capacity computed by wave equation analysis with failure load from static test. In order to determine proper...

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...

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...

Control of Random Crack Formation in Portland Cement Concrete Pavements
Random crack formation in concrete pavements, which is mainly due to the development of tensile stress caused by temperature-induced volumetric change and shrinkage deformation at early...

Dynamic Model for Analysis of Concrete Pavements
A new dynamic finite-element computer program, DYNA-SLAB, for the analysis of jointed concrete pavements subjected to moving transient loads is presented. The structural model for the...

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...
