Span-skewed effect on the response of I-girder prestressed concrete bridges

Abstract

Span-skewed bridges nowadays are constructed widely in the world and also in Turkey. This thesis is about the span-skewed effects on the responses of I-girder prestressed concrete bridges. The thesis prepared with this scope includes the following chapters. In the beginning, the general information about the bridges, the importance of the matter, previous studies about the subject are given. The formulations are also presented in this chapter. After that, simply supported I-girder pretension prestressed concrete bridge with five different models of 0, 21, 37.6, 57, 66.6 degrees of skewness angle, respectively are analyzed using Midas Civil computer program. This program is made especially for analyze and design all the components and all types of bridges by using the finite element method using the most common codes in the world. Response values like displacements and internal forces in the internal and external I-girders of the bridges, which obtained from analysis of different types of span-skewed bridges, are discussed. Then, the results and recommendations obtained from the analysis are given. The references are presented in the last chapter.
