A Model Specification for Pultruded Structural Shapes: An Industry Collaborative
The use of pultruded products is steadily increasing. To support this growth, the industry has identified the need for a collaborative effort in developing standards that form a base line...
Analysis and Design of SFRC Structural Elements
This paper presents and validates practical methods for flexural, shear and torsional analysis and design of fibrous reinforced concrete structural elements. The effects of both fiber...
Steel Fiber Reinforcement in Structural Application
Ribbon Technology Corporation's use of steel fiber reinforced concrete in the construction of their new manufacturing and office facility in Gahanna, Ohio. Cost savings are obtained by...
In-Situ Determination of the Compressive Stress-Strain Relationship of Multi-Wythe Brick Masonry
In-situ stress-strain relationships of existing multi-wythe brick masonry have been determined by introducing flatjacks into sawcuts made in the exterior wythe of the multi-wythe masonry....
Full-Scale Testing of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This phase of the program addresses the out-of-plane response to...
Strength, Behavior and Repair of Masonry Infills
Results of a series of experiments are presented on seismic performance of unreinforced masonry infill panels. The object of the investigation is to examine the loss of out-of-plane strength...
The Use of Built-Up Compression Members?A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....
Built-Up Compression Members for Noval Structural Systems
This paper discusses built-up compression members used in novel structural systems for two high-rise buildings: InterFirst Plaza at Dallas Main Center and Columbus Center in New York....
Design of Built Up Compression Members for Long Span Bridge Structures
This paper discusses the design of built up compression members for long span bridge structures including trusses and arches. Provisions of load factor design and use of high strength...
A New Theory of Built-Up Columns
In laced, battened and other built up columns the shear stiffness of the web can have a significant effect on the overall buckling load. At the present time, such columns are analyzed...
QST Rolled Shapes, a New Generation of HSLA Compression Members
With the development of the Quenching and Self-Tempering (QST) process by the Luxembourg steelmaker ARBED S.A., a new generation of High Strength Low Alloy (HSLA) rolled shapes has become...
Creep and Shrinkage of Composite Columns in Tall Buildings
The simultaneous presence of steel and composite columns in tall buildings is a common occurrence. The axial shortening characteristics of composite columns are influenced by creep and...
Performance and Serviceability of Composite Floors
Concrete slabs on steel deck are the most common type of floor system in use today. This system of construction is particularly advantageous when ultimate strength design (LRFD) is used....
The Innovative Concept of Semi-rigid Composite Beam
This paper discusses invention and development of a new type of composite beam called 'Semi-rigid Composite Beam.' This new type of beam is expected to behave better than presently used...
Vibration of Composite Floors
An AISC/CISC guideline on floor vibration is being prepared to help practitioners design to avoid floor vibration problems and to remedy problems that occur in practice. This paper provides...
Achieving Level Composite Steel Floors
Constructing deflected composite steel floors that are level is a complex operation, and one which requires cooperation and an exchange of information between the structural engineer and...
Dynamic Response of Variable Height Retaining Walls
A full-scale dynamic test was conducted on a 140 ft long reinforced concrete retaining wall. The observed resonant configurations were similar to those of a cantilever plate and showed...
Ambient Vibration Survey: Sunshine Skyway Bridge
An ambient vibration survey of the Sunshine Skyway Bridge was performed. The goal of this survey was to provide field data on the dynamic characteristics of the structure to corroborate...
Steel Bar Joist Performance: Design Deficiencies and Defects
Several failures of steel bar joist roofs have been investigated by the authors in the past decade. Many of these failures or performance problems have corresponded to bar joists manufactured...
Loma Prieta Response of an Eccentrically Braced Tall Building
Acceleration response records obtained during the October 17, 1989 Loma Prieta earthquake [Ms = 7.1] from the 47-story, eccentrically braced Embarcadero...
