Shear Design of Masonry Walls
The paper presents a summary of a research project carried out at the Swiss Federal Institute of Technology Zurich to develop a design method based on the ultimate strength of masonry...

Load-Bearing Capacity of Masonry Walls in a Critical Buckling Condition Taking Into Account the Restraining Effect of Floor Slabs
This paper studies the buckling effect of masonry walls and concrete floor slabs as a frame system. The frame is calculated according to the theory of II. order. The buckling length, the...

Wall/Floor-Slab Interaction in Brickwork Structures
The paper summarises the results of three series of tests on sections of brickwork structure carried out with a view to determining the characteristics of wall/floor slab joints in terms...

Notes on Statistics of Failures of Constructed Works
This paper is concerned with both catastrophic and sub-catastrophic failures, which may be categorized into three types: Safety (type S), Functional (type F), and Ancillary (type A). Often...

Failure Statistics Categorized by Cause and Generic Class
Failures can be classified into the three categories, ie. , SAFETY, FUNCTIONAL, and ANCILLARY. Within the causation definition, failures fall into five general areas: DESIGN DEFICIENCIES;...

Failure Investigation Process
The purpose of this paper is to consider the present failure investigation process, in order to assess whether failures are being properly investigated, and also whether sufficient information...

Alternative Procedures for Investigating Failures
Failures of engineered structures continue to occur. This is despite rapid advances in engineering theory, new, more sophisticated methods of analysis, and streamlined techniques for preparing...

Information Availability
There seems to be a great deal of concern about lack of availability of information concerning the results of failure investigations. In most court cases there is virtually no technical...

Failure Information Needs in Civil Engineering
If we are to learn from failures of engineered facilities, failure information must be in a useful form, and it must reach those who can effect improved practice. This paper discusses,...

Learning from Failures
Modern technology and innovation have created a gap between what the design drawings predict with respect to safety and serviceability of a structure and the real safety and serviceability...

Learning from Failures: Procedural Changes in the Design and Construction Process to Reduce Failures
This paper first defines failures and their number and scope in the design and construction fields. It then presents the writer's opinion as to the cause of the failures and...

Failure Investigations in Undergraduate Education
Author stresses the need for failure investigations in undergraduate education especially in Civil Engineering. The civil engineer often creates only one major project of a kind, and is...

Small Water Users�Planning Crisis
Planning to rehabilitate small water systems�both irrigation and municipal water supply�often is ignored. In contrast, planning for new construction and for operations/maintenance work...

Analysis of Cracking of I79 Bridge at Neville Island
A large crack was discovered to form in a girder of the I-79 Glenfield Bridge over the back channel of the Ohio River near Pittsburgh on January 28, 1977. A section of the girder containing...

Investigation of Catastrophic Failure of a Premium-Alloy Railroad Rail
In November 1983 an Amtrak train derailed at a speed of 72 mph (115 kph) at Woodlawn, Texas (in the vicinity of Marshall, Texas), resulting in four fatalities and twenty-four serious injuries....

Time-Dependent Damage and Creep of Brittle Rock
In this paper, some results of a combined analytical-experimental study of the relationship between subcritical microcrack growth due to stress corrosion and the time-dependent deformation...

General Continuum Models for Discrete Structures
New knowledge is presented about the structural behavior of a variety of large repetitive lattice configurations of the type appropriate for utilization in cosmic space. Focus is placed...

Liquefaction Flow Failure of Silty Sand by Torsional Cyclic Tests
The use of undrained strain-controlled cyclic torsional loading of anisotropically consolidated triaxial specimens (CyT-CAU tests), is proposed for evaluating liquefaction flow failure...

Torsional Simple Shear Apparatus for Drained and Undrained Cyclic Testing
Since a cyclic triaxial compression apparatus was first used to study liquefaction of saturated sandy soil, many different types of cyclic shear devices have been used to investigate drained...

Multi-Directional Irregular Loading Tests on Sand
In order to clarify the effects of irregular and multi-directional nature of load application on soil deposits during earthquakes, multiple series of laboratory tests were conducted on...
