The fifth edition of the Highway Capacity Manual (HCM2010), which updates HCM2000, will significantly update how engineers and planners assess the traffic and environmental effects of highway projects: It is the first HCM to provide an integrated multimodal approach to the analysis and evaluation of urban streets from the points of view of automobile drivers, transit passengers, bicyclists, and pedestrians; It is the first to address the proper application of micro-simulation analysis and the evaluation of those results; It is the first to discuss active traffic management in relation to both demand and capacity; and It is the first to provide specific tools and generalized service volume tables, to assist planners in quickly sizing future facilities.

Description:
This comprehensive and well-organized text provides a masterly exposition of the fundamentals of analysis and design of reinforced concrete shells and folded plates, commonly known as thin concrete roof structures. Divided into 20 chapters, the book presents practical designs of different types of domes, cylindrical shells, paraboloids, conoids, and groined shells, as well as various types of folded plates. The text also incorporates tables from ASCE Manual No. 31.
The book explains the subject in such a way that it can be easily understood even by students who have a basic knowledge of mathematics. Students will find the chapters on Folded Plates particularly useful as these structures are easy to build. After studying the book, their analysis and design can be done with greater ease.
Key Features :
Explains step-by-step the procedure for the design of various types of shells and folded plates.
The book is lecture-based, each chapter dealing with one topic. (This enables the teachers to plan their lectures in a proper fashion.)
Provides a large number of worked-out examples and review questions at ends of chapters, which are illustrative and act as brain teasers.
Gives large number of diagrams to illustrate the concepts discussed.
This reader friendly book is intended as a text for the postgraduate students of Civil Engineering/Architecture. As with all the books of Prof. P.C. Varghese, who brings in all his years of experience and expertise into his work, this book too would be of enormous help to practising engineers and architects besides the students.

DRIFT CAPACITY OF REINFORCED CONCRETE COLUMNS SUBJECTED TO DISPLACEMENT REVERSALS
Author: Santiago Pujol | Size: 0.4 MB | Format:PDF | Quality:Unspecified | Year: August 2002 | pages: 77
In previous tests of columns under displacement reversals in the inelastic range of response, different arbitrary displacement histories have been used. Comparisons of drift-capacity data from columns tested under different displacement histories can only be made if displacement-history effects are ignored. Possibly because of this reason, currently available methods for column drift capacity ignore displacement-history effects. To investigate whether drift capacity is a function of displacement history, sixteen cantilever columns were tested under various displacement patterns. The test results indicate that column drift capacity is sensitive to displacement history. For columns cycled beyond yield, drift capacity decreases as a function of the amplitude and number of cycles the column has experienced. Based on measurements of average unit strains in the transverse reinforcement, a model is proposed for estimating the drift capacity for a given column under any symmetric displacement pattern.

Collapse Modelling Analysis of a Precast Soft-Storey Building in Melbourne
Author: A. Wibowo , J.L. Wilson , E.F. Gad1, , N.T.K. Lam , P. Collier | Size: 0.3 MB | Format:PDF | Quality:Unspecified | Publisher: AUSTRALIAN EARTHQUAKE ENGINEERING SOCIETY; 2009 CONFERENCE, Newcastle, New South Wales, 11-13 December 2009 | Year: 2009 | pages: 11
Experimental field testing of a soft storey building in Melbourne has been undertaken
by Swinburne University of Technology in collaboration with The University of
Melbourne. The upper levels that consisted of precast walls and slabs were demolished
to the first floor. The soft storey open ground floor was a precast concrete frame with
connections significantly weaker than the members they connected. Four tests were
conducted with combination between load directions (strong and weak) and restraints of
ground slab (with or without ground slab). The experimental results show that soft
storey columns were found to have significant displacement capacity irrespective of
strength degradation.
An analytical model has been developed to predict force-displacement relationship of
the tested frame. The model includes the influences of: a) connection strength at column
ends; b) gravity rocking strength; and c) ground slab restraint. Results from the
developed model were found to be in excellent agreement with experimental test results,
showing that the top connection in the form of an unbonded high strength steel bars
dominated the overall load-deflection behaviour in the strong direction. However, the
gravity rocking mechanism dominated the behaviour in the weak direction. The
presence of the ground slab provides additional restraint to the column and significant
additional lateral strength to the system.

Author: Seval Pinarbasi , Dimitrios Konstantinidis , James M. Kelly | Size: 0.2 MB | Format:PDF | Quality:Unspecified | Publisher: 10th World Conference on Seismic Isolation, Energy Dissipation and Active Vibrations Control of Structures, Istanbul, Turkey, May 28-31, 2007 | Year: 2007 | pages: 12
Reconnaissance reports following strong earthquakes time and again point to the widespread
damage caused to buildings with soft stories. This study is motivated by the need to provide
mitigation strategies for these types of structures. There exists a general belief among
practicing engineers that seismic isolation can only be effective in reducing the seismic
demand for regular, uniformly stiff buildings but not for soft-story buildings since it is
thought that the flexibility of the soft story deems the isolation ineffective. This paper
present results from an extensive numerical investigation that dispels this misconception. It
looks at the results of modal and nonlinear time-history analyses conducted on simplified
models of a hypothetical five-story reinforced concrete building with a soft ground story to
draw conclusions on the efficiency of seismic isolation as the flexibility of the soft story is
increased. Comparison is made with how soft-story flexibility affects the corresponding
fixed-base building. Practical ways, if necessary, for increasing the efficiency of the
technique is also examined, showing that it benefits greatly by stiffening the soft story.
Success of the linear theory developed for base-isolated structures in predicting the basic
response parameters (both modal and seismic) when the structure has a soft ground story is
also assessed. The paper confirms that seismic isolation can be used as a viable mitigation
technique for soft-story buildings.
