A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...
Metal Truss Plates: Less than Full-Depth Penetration and Shear Buckling
This paper presents the results of two experimental studies on metal truss plates which are used to join members of wood trusses. The first study investigated the effect that less than...
Natural Decay Resistance of Glued-Laminated Beams
The natural decay resistance of untreated Douglas-fir heartwood specimens sampled from glued-laminated beams was evaluated using a modified agar plate test modeled after the European Standard...
The Effects of Bolt Over-Tightening on Bolted Connections
This paper describes a portion of the research program being conducted on structural connectors which have been over-tightened. Direct-Tension Indicators (DTI) may be specified for use...
Externally Stiffened I-Beam to Box-Column Connections
This paper is concerned with I-beam to Box-column connections stiffened externally. Experimental and theoretical findings on full-scale connection models are highlighted. The performance...
High Strength Shotcrete and Concrete on the SSC Project
This paper addresses the technical aspects related to the use of high strength shotcrete and concrete on the Superconducting Super Collider (SSC) project. 7,000 psi shotcrete and 8,000...
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,...
Shear Design Guidelines for Polyester Concrete Using Recycled Plastic
Previous research on the shear behavior of steel-reinforced polymer concrete (PC) beams has been very limited and no efficient design procedures have been proposed. In all the previous...
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...
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...
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...
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...
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...
Diaphragm Action of Cladding in Low-Rise Metal Buildings
An investigation of the contribution of cladding to the lateral stiffness of a metal building is presented in this paper. The diaphragm action of the cladding tends to redistribute the...
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,...
Testing of Concrete Curtain Wall Panels Reinforced with FRP Grids
The objective of this paper is to evaluate the suitability of Fiber Reinforced Plastic (FRP) grids for use as a structural; reinforcement in concrete curtain wall panels. This paper describes...
Development of Hardwood Glulam Timber Bridge Standards
Design standards and specification for 5.5 to 27.4 m(18 to 90 ft.) clear span hardwood glued laminated (glulam) highway bridges have been developed and are available from the Pennsylvania...
