Bridge Dynamics and Deflections, and Fatigue in Welded Beams


Book Description

Paper 1: Results are presented of an analytical study of the dynamic behavior of simple-span highway bridges traversed by heavy vehicles. Paper 2: Inasmuch as many highway bridges are now being built with elastomeric bearings, it was considered desirable to study the vibration effects of such bridges. Paper 3: The method and procedure used in a digital computer program are described to find horizontal and vertical movements of all joints of a truss, given the member stresses and the structure properties. Paper 4: Results are summarized of tests made to demonstrate the effect of details on the fatigue behavior of welded flexural members.




Vibration of solids and structures under moving loads


Book Description

Transport engineering structures are subjected to loads that vary in both time and space. In general mechanics parlance such loads are called moving loads. It is the aim of the book to analyze the effects of this type of load on various elements, components, structures and media of engineering me chanics. In recent years all branches of transport have experienced great advances characterized by increasingly higher speeds and weights of vehicles. As a result, structures and media over or in which the vehicles move have been subjected to vibrations and dynamic stresses far larger than ever before. The author has studied vibrations of elastic and inelastic bodies and structures under the action of moving loads for many years. In the course of his career he has published a number of papers dealing with various aspects of the problem. On the strength of his studies he has arrived at the conclusion that the topic has so grown in scope and importance as to merit a comprehensive treatment. The book is the outcome of his attempt to do so in a single monograph.
