Blast-Damaged Concrete Structures in Beirut
This paper describes the effect of blasting loads on structural members. It identifies predominant structural systems in war-damaged zones of Beirut and to explain typical damage mechanisms....
Physical Testing of Two R/C Skewed Slab Bridges with Integral Wall Abutments
Two one-third scale models of an existing reinforced concrete skewed slab bridge with integral wall abutments were tested statically to failure. Typically, these bridges are designed using...
Linear and Nonlinear Finite Element Analyses of RC Skewed Slab Bridges with Integral Wall Abutments
The design of rigid-frame skewed slab bridges is complicated by higher shears and moments near the obtuse corner (see Fig.1). While the finite element method can be used to compute these...
Testing of Concrete Permeability for Durability Evaluation
Field and laboratory permeability tests are being performed to evaluate the durability of concrete in Florida. These tests are part of an extensive research program to develop a durability...
Durability of Concrete Bridges in Virginia
This paper discusses four major types of deterioration found in concrete bridges: corrosion of the reinforcement, alkali-aggregate reactivity, freeze-thaw deterioration, and attack by...
Reliability-Based Expert Systems for Optimal Maintenance of Concrete Bridges
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...
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...
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
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...
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...
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...
