An Overview of the U.S. Coordinated Program for Masonry Building Research
The U.S. Coordinated Program for Masonry Building Research is a time-phased set of specific research tasks addressing materials, component and system behavior. The objective of the program...
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...
In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...
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...
Durability Design for Concrete Bridge Structures
The concept of durability design for concrete structures including bridge structures is proposed on the basis of comprehensive evaluation of materials, design details and construction...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Building a Better Landfill Liner
A soil liner project was sponsored by the EPA to provide information on the construction factors that affect the permeability of compacted soil liners. After construction of a field liner,...
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....
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,...
Normalized Damage Index for Evaluation of Buildings
A conceptual model for evaluation of structural damage is developed based on the fundamental idea of demand and capacity. The proposed formulation combines two recognized sources of damage:...
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...
Seismic Vulnerability Evaluation in Japan
The state of the art in Japan is reviewed on the evaluation of the seismic capacity of existing low- to mid-rise reinforced concrete buildings, taking into account the different resistance...
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...
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...
1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...
Reevaluation of Reinforced Concrete Slabs Subjected to Blast Effects
Failures in reinforced concrete shallow-buried structures subjected to the effects of severe dynamic loads are reevaluated by employing a modified Timoshenko beam formulation which includes...
