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...

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...

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...

Design and Field Performance of a Metal-Plate-Connected Wood Truss Bridge
This paper describes an on-going study on the design and performance attributes of an experimental wood-truss bridge. This is believed to be the first roadway bridge application of metal-plate-connected...

Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...

Prestressed Concrete Failures Due to Uplift
The paper presents some examples of prestressed concrete DOUBLE-TEE (DT) failures caused by hurricane Andrew. The DT's failures was mainly due to the negative moment created by uplift....

Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...

Seismic Renewal of Civil Infrastructure Systems
Almost all civil infrastructure systems are vulnerable to natural hazards such as earthquakes. The paper presents a broad perspective of the research needs for seismic renewal of the infrastructure...

Steady-State Analysis of Buckle Propagation
A novel finite element technique for the analysis of buckle propagation in pipelines is presented. The propagation pressure, propagation profile, the state of stress, and deformation during...

What Controls the Ultimate Load of a Glulam Dome?
A glulam dome is analyzed with the finite element method to determine the governing failure mode and ultimate snow loads. The dome consists of a triangulated network of curved glulam beams,...

Timber Structures
This paper deals with three different curvilinear timber structures of moderate spans - 120 feet to 200 fee +/-. In each of the three cases cited, the roof deck and boundary members are...
