| Summary: | 碩士 === 國立成功大學 === 土木工程學系碩博士班 === 100 === Due to the highly development of the computer-aided analytic software, finite element method has been much more popular and commonly used in civil engineering industry. In addition to enhance the design and strength of the buildings, it helps to improve the safety of the buildings, including steel structures. Safety and economy no doubt are the main concerns to engineers in the structural design process.
For the purpose to investigate the behavior of the structural responses in detail, software package ANSYS is used herein for the simulation analysis. It not only have the interface to set the material properties, but also to set the yield stress and failure stress. Mainly, three parts of work have done: firstly, the structural model is set by ANSYS Workbench DesignModeler through the data collected. Secondly, the tested static failure load is reffered into dynamic load to find the consistency of the stress-strain relations with the pre-set material properties. Finally, the failure mode and the responses of the frame members are investigated in detail when the structure is subjected to El Centro earthquake, and concluded with comparisons.
