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...
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...
Construction Scheduling for Public Sector Projects
The paper presents some types of scheduling systems that are utilized in Postal Service projects as well as the advantages and disadvantages of each. It is suggested that schedule approval...
Can We Save the Ogallala?
The useful life of the Ogallala Aquifer, which underlies seven western states, can be extended indefinitely through water conservation in the widest sense of the term. In addition to optimization...
Simulating Construction Operations by Microcomputer
Field operations on major construction projects involve complex interactions among construction equipment, materials and supplies, skilled craft resources, and technical and administrative...
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...
Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....
Soft Ground Tunneling of the Greenbelt Tunnels
Mergentime/Loram's contract for the construction of Section E-1d Greenbelt Route Tunnels includes construction of dual 1,770-foot tunnels in soft ground, a crossover structure,...
Flint Tunnel?A Project of Change and Challenge
The talk will deal with construction of a 12' diameter (8. 5' finished) tunnel in the City of Flint, Michigan. This 5-mile long sewer tunnel was constructed through...
Construction of Mt. Baker Ridge Tunnel
Mt. Baker Ridge Tunnel is a large diameter soft ground highway tunnel constructed through sensitive over-consolidated silts and clays. Its large diameter necessitates the construction...
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...
