Abstract
Description of a research project involving seismic analysis of structures utilizing the Abaqus Finite Element software package is provided in this presentation. The described undergraduate project was performed in the Civil Engineering and Construction Department at Georgia Southern with funding secured from the GSU Office of Research. As the initial phase of the project a series of preliminary tasks and investigations needed for conducting the planned investigation were conducted. These efforts involved mastering the essential specific skill sets needed for developing the proper Abaqus simulation models to accurately predict the response of structures subjected to prescribed earthquake loadings. During this phase of the investigation, a model of a fifteen-story high-rise steel building was created. This simplified model was developed to be used as a useful tool for performing an initial parametric study for analyzing more complex structures in the next planned phase of the study. The models developed in the new phase included the complete 3D solid models of the entire steel structures with detailed connections such a gusset plates and rivets, and the concrete structure models containing imbedded reinforced steel rebars and stirrups. The constructed simulation models were then subjected to a variety of dynamic excitations applied at base of the structures using the earthquake data generated from the SeismoArtif commercial software package. Procedures were implemented in the study to also incorporate the effect of damping in the models by first determining the natural frequencies of the structures.
Included in the presentation are sample developed simulation models and the corresponding results to illustrate how the dynamic response of structures can be determined and analyzed. These findings include the displacements and acceleration results at various critical points, as well as the maximum developed Von Mises stresses in the structures. The simulation models such as the ones developed in this study are of enormous importance, since these models can be used as an effective tool to design stronger and more resilient structures capable of safely withstanding earthquake excitations and other applied dynamic loadings.
