Concrete information for long-lasting concrete projects
This book is an all-new hardworking visual guide to the most popular home concrete and masonry projects, endorsed by the biggest manufacturer of concrete products in North America. Readers can save hundreds or even thousands of dollars with this book, since concrete materials are one of the least expensive and long lasting of all building materials.
Quikrete Guide to Concrete includes the most common home repairs, but goes a step further by offering some of the most exciting new techniques for building concrete countertops and form-cast landscaping features, as well as techniques for coloring and texturing concrete for designer finishes.

Almost all books available on fracture mechanics cover the majority of topics presented in this book, and often much, much more. While great as references, this makes teaching from them more difficult because the materials are not typically presented in the order that most professors cover them in their lectures and more than half the information presented is not covered in an introductory course at all.
Focusing on the needs of students and professors, Fundamentals of Fracture Mechanics offers an introduction to the discipline through careful editing and mindfulness toward the audience. The book begins with a review of the fundamentals of continuum mechanics and the theory of elasticity relevant to fracture mechanics. The following material has been carefully selected, only including topics important enough to be covered in a first course on fracture mechanics. Except for the last chapter, no advanced topics are covered. Therefore, instructors of elementary fracture mechanics courses can easily cover the entire book in a three-unit graduate-level course without having to spend too much time picking and choosing appropriate topics for the course from the vast knowledge presented in most fracture mechanic books available today.
Drawing on over 20 years of teaching, the author supplies practical and useful resources, including practice exercises designed to facilitate enjoyable learning and reference for further study. His clear, concise coverage of essential information makes the book ideal not only for an introductory course but also for self-study.

A computer vision-based approach for structural displacement measurement
Journal:
Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2010
Author:
Yunfeng Ji
Paper Abstract:
Along with the incessant advancement in optics, electronics and computer technologies during the last three decades, commercial digital video cameras have experienced a remarkable evolution, and can now be employed to measure complex motions of objects with sufficient accuracy, which render great assistance to structural displacement measurement in civil engineering. This paper proposes a computer vision-based approach for dynamic measurement of structures. One digital camera is used to capture image sequences of planar targets mounted on vibrating structures. The mathematical relationship between image plane and real space is established based on computer vision theory. Then, the structural dynamic displacement at the target locations can be quantified using point reconstruction rules. Compared with other tradition displacement measurement methods using sensors, such as accelerometers, linear-variable-differential-transducers (LVDTs) and global position system (GPS), the proposed approach gives the main advantages of great flexibility, a non-contact working mode and ease of increasing measurement points. To validate, four tests of sinusoidal motion of a point, free vibration of a cantilever beam, wind tunnel test of a cross-section bridge model, and field test of bridge displacement measurement, are performed. Results show that the proposed approach can attain excellent accuracy compared with the analytical ones or the measurements using conventional transducers, and proves to deliver an innovative and low cost solution to structural displacement measurement.

Author: HORIKOSHI K; RANDOLPH M F | Size: 1,2 MB | Format:PDF | Quality:Scanner | Publisher: Journal of the Japanese Geotechnical Society of Soils and Foundations | Year: 1999 | pages: 59-68 | ISBN: 1341-7452
Estimation of overall(or average) settlement and differential settlement are the two most critical issues in the design of moderate to large sized raft and piled foundations. Recent studies have shown that a central pile group can largely eliminate differential settlements, but it is still necessary to estimate the average settlement of the combined pile group and raft foundation. This paper presents a simple method of estimating the overall stiffness of piled rafts in a non-homogeneous soil with finite depth, based on the method of Clancy and Randolph(1996). Although the method enables the estimation of the piled raft's stiffness even when piles are installed beneath the full raft area, particular emphasis is placed on the situation where the pile support is limited to the central region of the raft. The method combines the so called 'equivalent pier method'(Poulos and Davis, 1980) and the 'flexibility matrix method'(Randolph, 1983). In the presented method, a piled raft is replaced by a 'capped pier'. Firstly, a simple method of estimating the overall stiffness of stubby piers in a homogeneous or a non-homogeneous soil is presented. The estimated stiffnesses are compared with those calculated by a finite difference approach(FLAC, Itasca Corporation, Version 3.22). The comparison shows that the simple method gives approximate overall stiffness of piers with a wide range of slenderness ratios(length/radius) and pile-soil stiffness ratios. Secondly, the applicability of the equivalent pier method to pile group analysis is examined for homogeneous soil conditions. The calculated stiffnesses are compared with those obtained by FLAC, and the so called 'hybrid' method(HyPR: Clancy, 1993) where the existence of individual piles is considered. The applicability of the 'capped pier' method to piled raft analysis is then examined.

Very few buildings finish on time or at the right price, and clients often criticise the fact that the finished building is not what they expected. Poor communication between the parties at one or more stages of the construction process seems to be the cause, and improved briefing practice has long been recognised as one important area where such communication could be improved.
This book examines the briefing process to understand its strengths and weaknesses and the problems involved, draws on the experience of other disciplines and industries, and identifies best practice and purpose innovations in the briefing process. It is strongly industry oriented while drawing on sound research.
