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...
Behaviour and Strength of Steel Frames with Semi-Rigid Connections
A research study was started at the Politecnico of Milan (Italy) to investigate the influence of the main governing parameters on the behaviour and strength of flexible frames. A sophisticated...
Joint Flexibility in Steel Frames
This paper investigates the effects of connection flexibility and panel zone deformation on the behavior of plane steel frames. The incorporation of these factors in frame analysis will...
Flexibility of Steel Seismic Moment Connections
Relevant Berkeley experimental results are critically evaluated to determine the flexibility of W18 W24 beam joints with and without stiffeners and/or doubler plates. The paper discusses...
Nonlinear Macroscopic Finite Element Model for Masonry Walls
A macroscopic finite element model which includes both transverse shear effects and nonlinearity due to cracking has been developed for masonry. These features are accommodated using a...
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...
Shear Stresses in Composite Masonry Walls
The behavior of composite masonry walls subjected to inplane loads is a subject that has received little attention during the last few years. The small amount of experimental and analytical...
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...
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...
Ensuring Quality Construction
This paper describes the US Army Corps of Engineers' efforts at procuring quality construction: 1) a three-phase approach (preparatory, initial, follow-up) was developed to...
Type C Fly Ash and Clay Stabilization
Because the soils onsite have a high swell potential, a 37 foot high retaining wall was designed with counterforts and was supported by pier foundations to limestone. In order to reduce...
Avoiding Disputes: The Construction Manager's View
Avoiding and minimizing contract disputes, from the construction manager's (CM) point of view, begins during the preliminary planning and design stages and continues throughout...
Construction Inspection?The Last Line of Defense
Construction inspection, or a quality assurance program, is typically the last line of defense in relation to claims for the constructed project. The quality assurance team should be a...
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...
