This synthesis presents the state of the practice regarding the use of geophysics for transportation projects. The report focuses on U.S. state and Canadian provincial departments of transportation (DOTs), and U.S. federal transportation agencies. The main points addressed include who is using geophysics and why, which methods and applications are the most commonly used, the use of in-house expertise compared with contracting private consultants, and how geophysical service contracts are procured and implemented. The scope was limited to how geophysics is being applied by geotechnical engineers during highway planning and construction activities. The information included in this synthesis was obtained from a review of the published literature; a survey of all 50 state DOTs, the District of Columbia, Canadian provinces, and selected federal government agencies; and follow-up telephone interviews designed to clarify or expand on particular aspects of some survey responses.

For the past 25 years, much knowledge and experience has been acquired by the engineering and construction industries on the use of rock-socketed shafts for support of transportation structures. This synthesis collected, reviewed, and organized the most salient aspects of this knowledge and experience to present it in a form useful to foundation designers, researchers, contractors, and transportation officials. The objectives of this report were to collect and summarize information on current practices pertaining to each step of the design process, along with the limitations; identify emerging and promising technologies; determine the principal challenges in advancing the state of the practice; and provide suggestions for future developments and improvements in the use and design of rock-socketed shafts. For this TRB synthesis report a literature review was conducted on all topics related to drilled shaft in rock or intermediate geomaterials. A questionnaire was developed and distributed to the principal geotechnical and structural engineers of U.S. state and Canadian provincial transportation agencies. Questions were grouped into the following categories: use of rock-socketed shafts by the agency, evaluation of rock and intermediate geomaterials, design methods for axial loading, design methods for lateral loading, structural design, construction, and field load and integrity testing.

The increasing demand for materials with superb properties in all types of technical applications requires the development of advanced materials and respective tools to characterise and predict the material properties and behaviour. This monograph highlights the latest developments and trends in advanced materials and their properties, the modelling and simulation of non-classical materials and structures, and new technologies for joining materials.

I am doing A&A work , we need to strengthen few rc beams with fiber wrap , i need design manuals or books based on BS standards with some reference. I need it urgently dear friends kindly help me.
A short review for design consideration of two common materials used in facade and curtain walling is presented. The characteristics of light-weight facade enveloping a building are different from the conventional steel or concrete structures. Glass cannot crack like concrete and it is much more brittle than steel. Aluminum involves many buckling modes similar to but more common than steel. Owing to the low Young modulus of elasticity around 1/3 of steel, buckling and large deflection nonlinear effects are important consideration in their design. This note summaries the most fundamental features of structures made of these materials.
