Interaction Between Beam and Steel Connections
The overall objective of the investigation is to study the behavior of a particular steel connection type, flush end plate steel connections, subjected to shear, axial forces, and possibly...
Design Property Values of Wood-Based Materials in LRFD Format
The development of a U.S. Load & Resistance Factored Design (LRFD) specification and supporting documents for engineered wood construction is nearing completion. The two key components...
Design of Connections in Wood Structures: LRFD vs. ASD
This paper provides a comparison of connection design capacities using load and resistance factor design (LRFD) procedures and allowable stress design (ASD) procedures....
Wood Diaphragm Design Capacities in LRFD Format
Wood diaphragms (horizontal and vertical) have performed well in resisting and transferring lateral forces imposed by major wind and seismic events. Resilient (ductile) behavior of wood...
System Factors in LRFD Format: A Multidimensional Judgment Call
A Load & Resistant Factor Design Specification for wood buildings is being completed. The Specification contains several revisions from the traditional 'repetitive member' factor...
Wood Bridge Design Using AASHTO LRFD Specifications
A nationwide project to develop a load and resistance factor (LRFD) design edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications...
Serviceability Reliability Analysis of Wood Beams
The effect of creep deformations on the serviceability reliability of single wood beams is investigated. Using stochastic load models and a time-dependent stress-strain relationship, the...
Fatigue Damage Accumulation Under Non-Gaussian Loads
The stochastic fatigue life prediction method, namely the Rayleigh approximation method, is almost exact when the loading is both normal (Gaussian) and narrowband. However, in many realistic...
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...
Seismic Resistance of Steel Fiber Reinforced Concrete Beam-Column Joints
This paper discusses the advantages of using steel fibers in seismic resistant beam-column connections. First, the effects of fibers on the various aspects of behavior of concrete are...
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...
Out-of-plane and In-plane Testing of URM Infills
This paper summarizes the out-of-plane followed by in-plane quasi-static testing of two, full-scale Unreinforced Masonry (URM) Hollow Clay Tile (HCT) infills. The testing is part of a...
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...
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...
Field Measurements of Wind-Induced Pressures on Roofs of Low Buildings
Full-scale measurements have been carried out on an experimental building, 3.3 m high, beside the football field at the Loyola campus of Concordia University. Wind-induced pressures have...
Site Load Testing of Full Scale Composite Concrete Floors
The paper presents the results of a load test carried out in 1982 on a continuous reinforced concrete slab with a permanent shuttering consisting of compressed straw (Stramit) or cement...
Vibration and Impact in Skewed Steel Bridges
The vibration and impact of skewed multigirder bridges due to vehicles moving across rough bridge deck are studied. The bridges are modeled as grillage beam systems. The vehicle is simulated...
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...
