Fatigue of Floating Offshore Structures: Modelling Uncertainty in Hydrodynamics and Fatigue Properties
For floating offshore structures such as tension leg platforms (TLPs), one form of loading uncertainty is due to nonlinear diffraction forces, which can excite lightly damped vertical...
Time Variant Reliability Under Environmental Loads
Time variant reliability with deteriorating resistance under a stochastic load process is considered. An outcrossing formulation for fatigue degradation is presented, and a simple and...
Durability and Ductility of Advanced Composites
In recent years, several fiber reinforced composites have been successfully used as prestressing materials for demonstration highway structures. Since these materials are relatively brittle...
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...
Flexural and Shear Behavior of Combined Concrete and Graphite Epoxy Beams
An experimental and analytical study of six graphite composite beams are presented. Four of the beams incorporated a reinforced concrete slab. The composite action and the effect of concrete...
Design Optimization of an All-FRP Short-Span Bridge
The objectives of this study are: a) to determine the feasibility of designing an all-FRP bridge, and b) to demonstrate the usefulness of optimization techniques in the design of FRP superstructures....
Nonlinear Analysis of RC Beams Using High Performance FRC Matrices

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....
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...
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...
Instrumentation Considerations for Nondestructive and Destructive Testing of Reinforced Concrete Slab Bridges
This paper examines the process of selection and calibration for instruments used in nondestructive and destructive field tests of a reinforced concrete slab bridge. Of great importance...
Acoustic Emission Monitoring of Stressed Composite Bars
