The Effect of Connection Flexibility on Steel Members and Frame Stability
With the advent of Load and Resistance Factor Design (LRFD) and the many existing moment-rotation curves for connections, the use of actual connection flexibility in the design process...

Buckling of Flexibly-Joined Simple Frames
A nonlinear analysis of plane elastic frames is presented. The static loading consists of both eccentric concentrated loads (near the joints) and uniformly distributed loads on all or...

An In-Plane Finite Element Model for Brick Masonry
A finite element model for brick masonry is reported. The model takes account of non linear deformations and progressive local failure. The failure may occur in the joints alone or in...

Behavior of Cavity Masonry Walls Under Out-of-Plane Lateral Loading: An Analytical Approach
In this paper, a finite element model is used to analyze cavity walls in an attempt to understand their complex behavior and to evaluate the adequacy of the assumptions embodied in the...

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...

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;...

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...

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...

Decision Support System for Tunneling
This paper first discusses methodologies for considering geological uncertainty in tunneling projects and for determining the most economic excavation and support methods under such condition;...

Rigid Pavement Rehabilitation: Interstate 95?Duval County, Florida
Rehabilitation studies have been conducted on Interstate 95 in Duval County, Florida. The rigid, unreinforced pavements were constructed in the late 1950's and 1940's....

Better Design Documents Through Constructibility Review
The Corps of Engineers (Corps) improves the quality of design documents by an extensive program to review in-house and Architect/Engineer (A/E) designs. This review is composed of several...

Inspection Costs Versus the Benefits Derived
The following text describes the experiences of a small suburban municipality located in Middle Tennessee before, during and after a five-year program of comprehensive inspection and testing...

Building Condition Assessment�An Owner's Perspective
The Port Authority of New York and New Jersey has recently instituted a program to inspect all of its buildings structures to insure structural integrity and public safety and to provide...

Revitalization of Existing Buildings: An Owner's Perspective
Revitalization of the large stock of existing buildings in this country is of paramount importance today to building owners, who want the value of existing properties to appreciate as...

Evaluation and Modernization of Veterans Administration Facilitaties
This paper discusses two examples showing in detail that procedures for building assessment require much consideration for engineers' programming and must be properly specified...

Changing Priorities in UK Construction Research
This paper addresses two types of situations to contend with in building assessment: aging structures all built at about the same time and to standards no longer acceptable, and newer...

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...
