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....
A Peice-wise Linear Evaluation of Masonry Infills Subjected to Out-of-plane Seiesmic Drift
This paper summarizes the out-of-plane testing and analytical modeling of a full-scale unreinforced masonry (URM) infilled frame and a bare frame without infilling. The testing was part...
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...
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...
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...
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...
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...
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...
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...
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...
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...
Aesthetic Considerations in the Design of a Stack Extension
The Connecticut D.E.P. mandated increase in height of the boiler stack at Backus Hospital in Norwich, CT presented many problems. Adding a new 45 foot vertical section atop the old brick...
