Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...
Masonry Cladding, an Expert System for Distress Diagnosis
An expert system for masonry cladding failure diagnosis was developed. The system provides a heuristic procedure for diagnosing the most probable causes of cladding distresses and failure...
Use of High Strength By-Product Gypsum Bricks in Masonry Construction
A new research aimed at producing high strength masonry bricks to be bonded with several types of joint materials other than conventional cement mortar, is introduced in this paper. This...
Masonry as a Structural Material
Four case studies are presented which illustrate the use of masonry as a structural material. Results of laboratory studies for unreinforced piers subjected to in-plane lateral forces,...
Failure Analysis of Masonry Structures
The use of smeared-crack and interface elements for the analysis of masonry structures is investigated. While a variety of structural problems can be solved with a combination of both...
Implementing Uncertainty Treatment in AI Development Environment
The seismic vulnerability of existing masonry buildings is investigated by an expert system prototype. Field inspectors have to provide answers which can be of a Boolean, fuzzy or probabilistic...
Fuzzy Measures in the Knowledge Based Diagnosis of Seismic Vulnerability of Masonry Buildings
Rules based expert systems and fuzzy logic have been employed to increase the speed and the reliability of the survey of masonry buildings, to forecast their seismic vulnerability....
Graphical Input Module for Masonry Design
Masonry Performance in the Coastal Zone
Investigators from the National Concrete Masonry Association (NCMA) surveyed the coastal areas of South Carolina from Charleston to Myrtle Beach during a seven day period just after hurricane...
Masonry Undergoes Rigorous Testing
Performance of Unreinforced Masonry Buildings During the Newcastle Earthquake, Australia
On December 28, 1989, an earthquake of Richter magnitude 5.6 shook the city of Newcastle. Newcastle is situated on the east coast of Australia only 100km north of Sydney. Eleven deaths...
Prototype Masonry Home Nearing Completion
Limit States Design in Masonry
This paper reviews some aspects of limit states design for masonry structures based primarily on experience with a new Canadian code. Steps in an advanced second order safety index analysis...
An Expert Design System in Teaching
A Tale of Two Laboratories
Two unusual research centers are built with the materials that will be studied in them, but the similarities end there. GE Plastics' $10 million Living Environments concept...
Improved Prediction of Masonry Durability Through Advanced Materials Science Methods
Several trends in the use of materials in civil engineering have made it imperative to improve the ability to predict the durability of masonry. This will require more emphasis on materials...
Premature Failures of Outdoor Masonry Pavements
The authors have investigated and repaired a number of premature inservice failures of masonry paving systems in recent years. These systems have become common, built over underground...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Building Joint Movement
Moisture leakage in masonry claddings occurs not only through copings and facial separation cracks, but also through failed sealant joints in the veneer. The factors affecting joint movement...
