In this paper ongoing research in the CEC supported BRITE/EURAM project P3091 is presented. In the project reliability based expert systems for inspection and maintenance of corroded reinforced...
Reliability of Highway Bridge Piers
Structural safety of reinforced concrete bridge piers supporting highway traffic is studied. Reliability indices for flexure, shear, and combined flexure and axial load limit states at...
Optimal Design of Building Structures Using the Predetermined Sections
A practical optimization algorithm for the member design of building structure is presented in this paper. The emphasis is particularly concentrated on the practical applicability of the...
A Shear Transfer Model for Floor-To-Wall Connections in Concrete Masonry Structures
Based upon experiments conducted at the Univ of California, San Diego (UCSD) on floor-to-wall connections in concrete masonry structures, a constitutive model was developed for the overall...
An Innovative Connection Detail for High-Rise Buildings
Composite columns consisting of hollow steel tubes filled with high strength concrete have been used in high rise building construction in the USA and Far East Asian countries. The focus...
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...
Mapping Structural Damage to Monetary Damage
Earthquake damage estimation/prediction is still an area which requires expertise and judgment of the experts in the field. Making the predictions/estimates more accurate is an area of...
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...
Nonlinear Analysis of RC Beams Using High Performance FRC Matrices
The results of a nonlinear analysis model of reinforced concrete beams using a high performance fiber reinforced cement based matrix, particularly SIFCON (Slurry Infiltrated Fiber Concrete)...
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...
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...
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...
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....
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...
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...
