Framework for scanning modal parameters of bridges from vehicle responses utilizing the Vehicle Scanning Method (VSM) Advanced Vehicle Scanning Method: Bridge Modal Parameter Identification delivers a complete theoretical framework for scanning of the modal parameters (frequencies, damping ratios, and mode shapes) of bridges from vehicle responses. This book provides comprehensive coverage of the application of the Vehicle Scanning Method (VSM) for different types of bridges, which has the advantage of mobility, economy, and efficiency over the conventional, direct method. Most of the materials presented in each chapter have been published as technical papers in high-ranking international journals, which were subjected to critical reviews. The contents of the book have been arranged such that they are reflective of the progressive advancement of the VSM technique. Edited by a highly qualified team of authors including one of the original developers of the VSM technique, Advanced Vehicle Scanning Method includes information on: The theoretical basis for bridge frequency identification and scanning methods enhanced by software and hardware toolsThe damping formula for determining the bridge damping ratio from the spatial correlation of the front and rear wheels of a two-axle test vehicleThe methods for removing the damping distortion effect on bridge mode shape recovery with no prior knowledge of bridge damping ratiosThe theoretical basis of scanning frequencies, damping ratios, and mode shapes using VSM for various types of bridges, such as curved bridges and thin-walled girdersAdvanced Vehicle Scanning Method is an essential reference on the subject for researchers working on bridge dynamics, graduate students in programs of study related to vehicle-bridge interaction, and practicing bridge engineers.

This book is an updated, accessible approach to nonlinear structural analysis, focusing on the physical interpretation of nonlinear behaviors in framed structures. Unlike its predecessor, which was mathematically oriented, this revised edition simplifies the analysis by using the universally valid "rigid body rule," emphasizing physical understanding over intricate mathematical formulations.Covering key structural forms — plane and space trusses, plane and space frames — the book addresses nonlinearities that occur in structures due to large deformations under loads. By employing the finite element method (FEM), specifically the stiffness-based formulation, the work offers practical insights into nonlinear behaviors, including buckling, geometric stiffness, and the unique 3D rotational behavior of moments. Throughout, clear examples and closed-form solutions enhance understanding, and guidance on path-tracing methods addresses challenges like postbuckling and critical points.This book is ideal for researchers, practicing engineers, and students aiming for a practical, physically grounded perspective on nonlinear structural analysis, particularly for complex framed structures where traditional FEM approaches fall short.
