  HB 48—1999 STEEL STRUCTURES DESIGN HANDBOOK
Posted by: ir_71 - 06-20-2011, 03:55 AM - Forum: Steel - Replies (1)

HB 48—1999 STEEL STRUCTURES DESIGN HANDBOOK

Author: L. Pham, P. Boxhall D., Mansell | Size: 1.6 MB | Format: PDF | Publisher: Standards Australia | Year: 1999 | pages: 156 | ISBN: 0733727549

[Image: 53796747624729159351.jpg]


[Image: info.png]

The Handbook contains three parts and each member of the consortium of engineers who wrote it participated as author of the design rules, or author of the worked examples, or as editorial adviser representative of future users. Therefore, the consortium includes research engineers from CSIRO and the universities, and designers from large and small practices, and from the construction and fabrication industries. It is believed that the outcome is a book which is technically sound, and well-suited to use by a designer who wishes to make decisions with minimal design aids and only a handheld calculator. The users of this Handbook are assumed to be qualified to undertake structural design.
Part I of the book provides advice and rules in a structure similar to that of the first eleven sections of AS 4100. The chapter and paragraph numbers, titles, and notation, are kept as close to those of AS 4100 as possible so that designers can move readily from one document to the other in order to use the tier of their choice.
Chapter 1 sets out the scope and the limitations for the use of this Handbook and
Chapter 2 lists the relevant standards with which the materials should comply.
Chapter 3 describes the difference between Working Stress and Limit States Design and describes the classes of Limit States which should be anticipated. It also sets serviceability limits. Chapter 4 defines the methods of analysis for the purposes of obtaining design effects and displacements, the forms of construction, the assumptions for analysis and the limitations to the use of plastic analysis in this Handbook.
Chapters 5 to 8 provide rules and procedures for calculating the strength of members subjected to flexural, compressive, tensile and combined actions. Chapter 9 recognizes the fact that a large part of Australian structural practice uses a very limited and discrete range of fasteners. It therefore also contains simple tables of bolt and weld capacities, and of the relevant geometric data on hole sizes and edge distances.
Chapter 10 identifies circumstances under which brittle fracture is not likely to be a problem. Chapter 11 presents a simplified approach to design against fatigue. Advice is given only on situations where the stress range is constant and material is thin. The form of expression of the S-N curves is simplified by changing the definition of the detail category to reduce the number of ‘variables’ in the equations. The structure of
Chapter 11 is such that the designer will often be able quickly to exempt the detail from fatigue analysis with little or no computation. A more fundamental change in philosophy is that the Handbook enables the designer to calculate the life of the detail when it is fatigue-prone.
Part II is a set of design aids in the form of tables and charts derived from the dimensions of standard sections and from the rules in the Chapters of this Handbook. They speed up the design process and reduce the opportunity for computational error.
Part III consists of worked examples of the application of the rules in Part I. The examples are chosen to demonstrate realistic situations and have been worked out by designers in active commercial practice.

  ANALYSIS AND DESIGN OF HAMMER HEAD BRIDGE PIER USING STRUT AND TIE METHOD
Posted by: ptqc06 - 06-18-2011, 04:05 AM - Forum: Concrete - No Replies



ANALYSIS AND DESIGN OF HAMMER HEAD BRIDGE PIER USING STRUT AND TIE METHOD

Size: 1.81 MB | Format: PDF

[Image: 53970398900320185163.png]


[Image: info.png]

The main advantages of truss model are their transparency and adaptability to arbitrary
geometric and loading configuration. In strut-and-tie modeling, the internal stresses are
transferred through a truss mechanism. The tensile ties and compressive struts serve as
truss members connected by nodal zones. The advantages have been thrust into the back
ground by several recent developments of design equations based on truss models,
The present study is focus on developing a uniform design procedure for applying the
strut-and-tie modeling method to hammerhead pier. A study was conducted using
hammerhead piers that were previously designed using the strength method specified by
code. This structure was completed and had put into service. During the inspection,
cracks were observed on the piers. The scope of this study is to highlight the application
of a newer generation strut-and-tie model, which is not practice at the time of the
original design. Depth to span ratios varies from 1.5 to 2.11 and the girders are
transferring loads very close to the support edge, making these hammerheads ideals
candidates for strut-and-tie application. This study only focus on comparison the
reinforcement detail drawing produce previously designed using the strength method,
and reinforcing requirement using strut-and-tie model.
Based on the design studies, a well-defined procedure for designing a hammerhead pier
utilizing the strut-and-tie model was established that may be used by bridge engineers.
There could be numerous reasons for the crack to develop. Shrinkage, stress
concentration or some erection condition may be a few of them

  Strut-and-tie modelling of reinforced concrete pile caps
Posted by: ptqc06 - 06-18-2011, 03:54 AM - Forum: Concrete - No Replies

Strut-and-tie modelling of reinforced concrete pile caps

Size: 11.5 MB | Format: PDF

[Image: 64002765956476640444.png]


[Image: info.png]

Shear failure is an important failure mode for pile caps, civil engineering structures in
reinforced concrete, often used as substructures for bridges. However, while relatively
thin slabs, such as flat slabs for office buildings, have been subjected to intense research
in the past, there is a lack of generic models for thicker structures today and building
codes are still based on less appropriate empirical or semi-empirical models. For this
reason, the design of pile caps for shear failures, and punching failure in particular,
often results in dense reinforced structures. A rational approach to shear failures in
three-dimensional structures is needed to provide a safe and efficient design of pile
caps

  OFFSHORE STANDARD DNV-OS-C502 OFFSHORE CONCRETE STRUCTURES

OFFSHORE STANDARD DNV-OS-C502 OFFSHORE CONCRETE STRUCTURES

Author: DET NORSKE VERITAS | Size: 10.7 MB | Format: PDF | Publisher: DET NORSKE VERITAS | Year: 2004 | pages: 100

[Image: 33820591124828762423.jpg]


[Image: info.png]

301 The standard is applicable to Design, Construction, Inspection and Maintenance of Offshore Concrete Structures, using concrete as the structural material in the support structure as defiied in 302 below.
302 The standard can be used in the structural design of the following types of support structures:
~ GBS (Gravity Based Structures) offshore concrete structures for oil/gas production
~ GBS structures for oil/gas production with oil storage facility
~ Floating concrete structures for production of oil/gas. The structure may be of any type floating structure, i.e. Tension leg platform (TLP), Column stabilised units and Barge type units
~ Concrete harbours
~ Artificial concrete export/import harbours, either floating or fixed and with storage facilities, allowing transport of articles and goods with small boats to the artificial harbour
for reloading on large sea going vessels. Cargo may be different types or ore or oil/gas
~ Deep water caisson type concrete foundation of bridges
~ Floating foundations for bridges, parking houses or storage buildings.
303 Appendices A to F are appended to the standard. These appendices contain guidelines for the design of Offshore Concrete Structures.
304 Floating Offshore Concrete structures shall be designed with freeboard and intact stability in accordance with DNVOS-
C301. For temporary phases the stability shall be in accordance with DNV Rules for Planning and Execution of Marine Operations.
305 The development and design of new concepts for Offshore Concrete Structures requires a systematic hazard identification process in order to mitigate the risk to an acceptable risk level. Hazard identification is therefore a central tool in this standard in order to identiSl hazards and mitigate these to an acceptable risk level.
