Unified Code Provisions for Concrete Bridges
Provisions on limiting the flexural reinforcement adopted in the new AASHTO LRFD Specification for Bridge Design are summarized (1). They address minimum and maximum levels of reinforcement...
Mechanical Behavior of Dowels Embedded in Concrete
In this paper an experimental investigation on the behavior of dowels embedded in concrete is described. The dowel strength under monotonic forces with two different boundary conditions...
Creep Analysis of Composite Steel-Concrete Members with Deformable Connectors
The long-term analysis of composite steel-concrete beams with elastically deformable connectors is presented. The basic integro-differential equation governing the problem is solved by...
Cut and Cover Construction of the SSC Injector Tunnels
The injector system of the Superconducting Super Collider (SSC) constitutes the string of tunnels where protons are accelerated to near the speed of light and injected into the main collider...
An Overview of Shotcrete Usage on the SSC
Shotcrete has been widely used on the Superconducting Super Collider for initial support of tunnel excavations in both the strong and weak rock formations encountered. Different types...
Dynamic Testing of Unreinforced Brick Masonry Infills
A significant seismic hazard may exist when unreinforced masonry infill panels fall out of their surrounding frames as a result of excessive accelerations applied normal to their plane....
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...
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...
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...
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...
Recent Studies of the Behaviour of Semi-Rigid Composite Connections
Following renewed interest in the semi-rigid properties of joints in steel frame structures, a more recently identified area of research has been the study of composite connections. The...
Rigid Beam-To-Column Connection Detail for Circular Composite Columns
Steel pipes with relatively thin wall thickness and filled with high strength concrete have been used in building construction. Some of the advantages of this type of column include eliminating...
Seismic Response and Retrofitting of Non-Ductile Reinforced Concrete Bridges
The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the...
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...
Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...
Design and Construction of Post-Tensioned Concrete Floor Systems
This is a summary of the original full length paper which is available from the author. This paper assumes a basic technical knowledge of reinforced concrete design and prestressed concrete...
Tests of Full-Size Pretensioned AASHTO Beams with Debonded Strands
A summary of an experimental investigation dealing with the effects of strand debonding on the flexure and shear behavior of simply supported pretensioned AASHTO beams with a cast-in-place...
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...
