Structural Design and Analysis

Analysis and Design of Integral Abutment Bridges

Integral abutment bridges (IABs) have been a preferred bridge construction configuration in the recent three decades due to many advantages such as low construction and maintenance cost, superior structural performance against live loads and seisimic loads, smoothe ridability and less noises. In spite of the increased preference and growing body of research, detailed design guidelies are not yet available in AASHTO LRFD and/or other design codes. From this perspective, CNU SAL has been doing a lot of works and research to propose new design standards that lead bridge designers easily adopt IABs in their design.

Structural Analysis and Design

Various constructed civil structures exist now experiencing both expected and unexpected loads, and new types of structures are being developed daily and yearly to thrive in many countries. CNU SAL develops new analysis and design approaches of these structures to maximize economic feasibility and keep their safety.
