Preface

Over the past decades, the society requires the creation of new bridges to ensure good and effective infrastructure. This is true for both effective urban and rural areas and for roads, railways and other transport modes including bicycles. Therefore, the field of bridge engi‐ neering is one of the most related fields to meet those needs. Bridge engineering consists of a lot of scientific concepts and includes a huge investment of money. It is very much needed to design any bridge economically and construct it with proper knowledge and mainte‐ nance.

Bridge engineering has developed in line with the new millennium. Although the general techniques of bridge design have been established for thousands of years, every bridge presents complicated factors that must be taken into consideration, such as the geology of the surrounding area, the amount of traffic, weather conditions and construction materials. Sometimes these factors are miscalculated, or something occurs that the bridge designers did not expect. New construction techniques and new materials are emerging. There are also new issues faced by the bridge-building industry relative to the research associated with these new techniques and materials. A detailed description of each chapter has been made as follows:
