Parametric Analyses of RC Shear Walls by FEM
In this paper, nonlinear behavior of reinforced concrete shear walls is studied by using the finite element analysis. We applied numerical analyses to a wide range of parameters, such...
Strength Evaluation of Existing Reinforced Concrete Structures
The load test as described in ACI 318-83 Chapter 20, entitled 'Strength Evaluation of Existing Structures,' was conducted at 60%, 80%, and 100% of the calculated...
Flexural Strength of Ultra-High Strength Concrete Members
Various proposals have been made for the pridiction of strength of high strength concrete sections. One of the most important parts of any strength computation procedure is the assumption...
Member Design Equations for a LRFD Wood Specification
A key step in the preparation of a load and resistance factor design (LRFD) based design specification for engineered wood construction is the selection of the behavioral equations for...
Inelastic Performance of Single-Story Masonry Shear Walls
Twenty-two story-height reinforced masonry shear walls have been tested to examine the influence of the applied axial stress, and the amount of vertical and horizontal reinforcement on...
Nonlinear Finite Element Analysis of Experiments on Two-Story Reinforced Masonry Shear Walls
Nonlinear, static finite element analyses are being used for correlation with experiments conducted on one-story reinforced masonry shear walls, and for the prediction of and correlation...
Use of Experimental Data to Develop Probable Behavior
The intent of this paper is to present results of research that studies the performance of the University of Colorado walls tested by Professor Benson Shing. These walls would be classified...
Bond and Dowel Action of a Main Bar in a RC Beam
The bond and dowel action are analytically treated independently on each other in most cases. The bond behavior may be, however, much affected by the dowel action in structural members....
Architectural Configurations in Vina del Mar
This paper identifies the architectural characteristics of 121 reinforced concrete buildings in Vina del Mar. These characteristics are related to the damage statistics for the building...
Ductility and Failure Characteristics of Concrete and Rock Subjected to Complex Load Paths
Strength, ductility and the complex material response features of concrete and rock should be evaluated through carefully planned material properties test programs designed to subject...
A Damage Model for Reinforced Concrete
The damage index developed by the authors models concrete damage as a low-cycle fatigue phenomenon. By quantifying the energy dissipated as a fraction of the total energy dissipation capacity,...
Seismic Vulnerability and Retrofitting of Buildings. Recent Experiences in Mexico City
Measures taken in Mexico City after the 1985 earthquake to evaluate the safety of existing buildings, to strengthen damaged structures and to retrofit those that were considered to need...
Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...
Nonlinear Analysis for the Aseismic Strength of Highrise Steel Frame With Semi-Rigid Joints by Pseudo-Elastic Approach
This paper suggests that the direct stiffness method is still useful in dealing with the nonlinear analysis for the aseismic capacity of highrise steel frame while the Pseudo-elastic approach...
Amelioration of Stirrup and Compression Reinforcement on the Ductility of Reinforced High-Strength Concrete Beam
18 rectangular high strength concrete beams were tested to investigate their ductile behavior. The results show that it will be more advantageous, for ductility, to choose the compressive...
Seismic Strengthening of a Historic Unreinforced Masonry Building
The building involved is a four-story unreinforced masonry structure. Considerations related to development of design criteria are presented along with retrofitting strategies. The building...
Seismic Strengthening of a Tall Masonry Building
The design of a strengthening system for a tall building is proposed using ductile reinforced masonry shear walls. This innovative design concept produced a system that controlled the...
Recent Research on Repair and Strengthening of Reinforced Concrete Structures
As part of the research effort organized following the 1985 Mexico City earthquake, a series of tests were conducted at the University of Texas at Austin to assess the performance of redesigned...
Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
Recent Developments in Testing Base Isolation Systems
One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of...
