Moving Freight with Better Trucks: Improving Safety, Productivity and Sustainability

Posted by: fuchiguis - 08-29-2012, 01:59 AM - Forum: Archive - No Replies

Moving Freight with Better Trucks: Improving Safety, Productivity and Sustainability
OECD / ITF | 19 Apr 2011 | ISBN: 9282102930 | 361 pages | PDF | 4 MB

The purpose of this report is to identify potential improvements in terms of more effective safety and environmental regulation for trucks, backed by better systems of enforcement, and to identify opportunities for greater efficiency and higher productivity.

The report is based on a review of literature, consultation among stakeholders, and research and analysis from working group members. It also presents the results of a comprehensive benchmarking study of 39 truck configurations in operation around the world – from typical workhorse vehicles to very high capacity vehicles – and assesses their performance in terms of dynamic stability, productivity and impact on the infrastructure.

Optimization and Nonsmooth Analysis

Posted by: lisine - 08-28-2012, 12:25 PM - Forum: Mathematics (Engineering and Scientific) - Replies (1)

Optimization and Nonsmooth Analysis

Mathematical Reviews said of this book that it was "destined to become a classical reference." This book has appeared in Russian translation and has been praised both for its lively exposition and its fundamental contributions. The author first develops a general theory of nonsmooth analysis and geometry which, together with a set of associated techniques, has had a profound effect on several branches of analysis and optimization. Clarke then applies these methods to obtain a powerful, unified approach to the analysis of problems in optimal control and mathematical programming. Examples are drawn from economics, engineering, mathematical physics, and various branches of analysis in this reprint volume.

Some Recent Problems in Applying ACI 318 Deflection Criteria

Posted by: aslam - 08-28-2012, 02:18 AM - Forum: Journals, Papers and Presentations - No Replies

SOME RECENT PROBLEM IN APPLYING ACI 318 DEFLECTION CRITERIA

[img]

[/img]

Deflection criteria should be based on all things known to affect deflection (loads, modulus of elasticity, etc.)

No real penalty for designers – Computers make complicated deflection calculations transparent

Minimum thickness criteria should not permit thinner slabs than required by computation

Design Of Mechanical Joints

Description

A cornerstone publication that covers the basic principles and practical considerations of design methodology for joints held by rivets, bolts, weld seams, and adhesive materials, "Design of Mechanical Joints" gives engineers the practical results and formulas they need for the preliminary design of mechanical joints, combining the essential topics of joint mechanics...strength of materials...and fracture control to provide a complete treatment of problems pertinent to the field of mechanical connections.

Introduction to Mechanical Joints Elementary Concepts of Strength and Fracture Effect of Lateral Forces Indeterminate Static Equilibrium Cross-Sectional Geometry Combined Stress Criteria Response in Shear Torsion Deflection Criteria Buckling of Columns and Plates Bending of Plates Design of Curved Elements Preliminary Considerations of Fasteners Design of Rivets Behavior of Individual Bolts Selection of Bolt Materials The Problem of Stress and Strain Torque Equations and Friction Strength and Design Criteria Control of Torque and Preload Selection of Working Loads Modern View of Bolt Preload Riveted and Bolted Joints Basic Formulas for Rivets Formulas for Eccentric Shear Performance of Riveted Joints Rigid Bolted Connection Effect of Gasket Stiffness of Flange in Compression Conventional Diagram of Bolt Preload Theories of Joint Preload Calculation of Spring Constants Symmetrical Splice Connection Flanges and Stiffeners Comments on Gasket Effects Tightness Criterion Spacing of Bolts Mechanics of Flange Rotation Design of Straight Flanges Design of Ribbed Flanges Stiffeners Compact Flanges Design of Clamps and Pipe Joints Interference Fit Split Hub Criteria Single-Pin Clevis Joint Rigid Clamp Application Design C-Clamp Vessel and Pipe Supports Tubular Joints Coupling and Pin Connections Design of Cotter Joints Key and Spline Connections Technology of Pipe Coupling Single Bolt Fitting Design of Eyebar Joints Sizing of Pins Coupling Links Wire Rope Fittings Thread Forms for High Pressure Closures Design of Welded Joints Typical Welded Joints Allowable Weld Stresses Crack Initation and Fatigue Design Assumptions Analysis of Fillet Weld Weld Line Formulas for Design Welded Lap Joint.
