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...
Effects of Earthquake Intensities and Site Conditions on the Reliability of RC Frame Structures
This paper evaluates the effects of seismic zone factors and site coefficients on the seismic reliability of reinforced concrete frame structures. A nine-story intermediate moment-resisting...
A Prototype Expert System for Rapid Visual Screening of Seismically Hazardous Buildings in California
A rapid visual screening expert system, California Rapid Building Seismic Evaluation Expert, was developed to enable efficient and effective identification of seismically hazardous buildings...
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...
