Punching Shear Retrofit Method Using Shear Bolts for Reinforced Concrete Slabs under Seismic Loading
The shear bolts are a new type of transverse reinforcement developed for retrofit of existing structures
against punching. This research focuses on how the shear bolts can improve the punching-shear
capacity and ductility of the existing slab-column connections under vertical service and lateral
seismic loads.
A set of nine full-scale reinforced concrete slab-column connection specimens were tested under
vertical service and cyclic loads. The vertical (gravity) load for each specimen was kept at a constant
value throughout the testing. The cyclic lateral drift with increasing intensity was applied to the
columns. The specimens were different in number of bolts, concrete strength, number of openings,
and level of gravity punching load. Strains in flexural rebars in the slabs, crack widths, lateral loads,
and displacements were obtained.
The peak lateral load (moment) and its corresponding drift ratio, connection stiffness, crack width,
and ductility were compared among different specimens. The testing results show that shear bolts can
increase lateral peak load resisting capacity, lateral drift capacity at peak load, and ductility of the
slab-column connections. Shear bolts also change the failure mode of the slab-column connections
and increase the energy dissipation capacity.
The thesis includes also research on the development of guidelines for shear bolt design for concrete
slab retrofitting, including the punching shear design method of concrete slab (with shear bolts),
dimensions of bolts, spacing, and influence of bolt layout patterns. Suggestions are given for
construction

This book, part of a series of four, offers a detailed analysis of urban design, covering the streets, squares and buildings that make up the public face of towns and cities. It outlines the theory of the principal features of urban design from which method is developed and provides a better understanding of the main elements of urban design. This includes the arrangement, design and details of the streets and squares, and the roles they play in city planning.
This third edition includes chapters on "Sustainable Urban Design" and "Visual Analysis", introducing the latest theories and influences in the field and bringing greater practical significance to the book. Cliff Moughtin explores the street and square in terms of function, structure and symbolism and examines fine examples in their historical context. These are set against the background of the laws of urban design composition, culled from Renaissance and modern writers.
* Gain an understanding of the detail of urban design from towns and buildings to squares and streets
* Learn from examples in their historical context and see the evolution of urban design
* New case studies help relate theory to practice

The Messina Strait Bridge
A Challenge and a Dream
By Fabio Brancaleoni, Giorgio Diana, Ezio Faccioli, Giuseppe Fiammenghi, Ian P.T. Firth, Niels J. Gimsing, Michele Jamiolkowski, Peter Sluszka, Giovanni Solari, Gianluca Valensise, Enzo Vullo
This book describes the enormous depth of work carried out since the early seventies on the Messina Strait Bridge, up to the recent award of the detailed design and construction contract. This important work has included extensive studies, concepts and design developments, with far reaching applications, which have all confirmed the feasibility of this huge endeavour and have led to the optimisation of costs and expected performance levels.
Attention is focused not only on the design itself, but also on the context for the project (e.g. historical, geological, seismo-tectonic and wind conditions; structural and mechanical properties; project management and financial aspects; and environmental considerations), and on the great challenges involved. Thus, considering the innovations and specific solutions adopted in overcoming the challenges presented by constructing a world record span of 3,300 metres at this site, it becomes clear how the Messina Strait Crossing will take its place as a masterpiece in bridge engineering history.
This book will be of interest to bridge and structural engineers, geotechnical and wind engineers, mechanical and earthquake engineers, graduate students in all these areas and all others with a broad interest in bridge design and engineering.

These are a set of guidelines and standard practice documents related with design, formwork, placing and curing of concrete on floors and slabs, namely:
ACI 302.1R-96
ACI 360R-92
ACI 308-92
ACI 309R-87
ACI 117-90/117R90
ACI 224.3R-95
ACI SP-2(92)
CP-10(95)
I hope that these documents are still useful for this forum, as they deal with fundamental issues always present in the engineering field.

Product Description
This compendium of essential formulae, definitions, tables and general information provides the mathematical information required by students, technicians, scientists and engineers in day-to-day engineering practice. A practical and versatile reference source, now in its fourth edition, the layout has been changed and the book has been streamlined to ensure the information is even more quickly and readily available - making it a handy companion on-site, in the office as well as for academic study. It also acts as a practical revision guide for those undertaking BTEC Nationals, Higher Nationals and NVQs, where engineering mathematics is an underpinning requirement of the course.
All the essentials of engineering mathematics - from algebra, geometry and trigonometry to logic circuits, differential equations and probability - are covered, with clear and succinct explanations and illustrated with over 300 line drawings and 500 worked examples based in real-world application. The emphasis throughout the book is on providing the practical tools needed to solve mathematical problems quickly and efficiently in engineering contexts. John Bird's presentation of this core material puts all the answers at your fingertips.
* A compendium of the maths essential to all engineering disciplines
* Succinct, easily accessible information, combined with comprehensive coverage - ideal for ongoing reference by both professional engineers and students alike
* New, improved structure to make information available even more quickly
