Civil Engineering Graduate Seminar March. 15th
Time: 4-5pm, Thursday (March. 15th)
location: Dow 642
Public welcome

Topics:

1. Integration of Mainshock-Aftershock Sequences Into Performance-Based Engineering
Presenter: Ruiqiang Song, Ph.D. Student, Department of Civil and Environmental Engineering, (Adviser: Dr. Yue Li)

Abstract: During earthquake events, it is very common to observe many aftershocks following the mainshock. Although they are normally smaller in magnitude, aftershocks may have a large ground motion intensity, even longer duration and different energy content. Aftershocks have the potential to cause severe damage to buildings and threaten life safety even when only minor damage is present from the mainshock. However, most of current seismic risk assessment researches focus on risk due to a mainshock event only. The primary goal of this research is to systematically integrate aftershock seismic hazard into Performance Based Engineering through a combination of analytical studies with structural degradation models. In this study, the global-level hysteresis damage models is calibrated, structural Collapse Capacity subjected to Mainshock and aftershock sequence is carried out by performing incremental dynamic analysis, the effect of frequency content on structural collapse capacity are also checked and ground motion attenuation relationship of response spectral values are presented.

2. Building Information Modeling: A Demonstration of Parametric Modeling and its Use in the Construction Industry
Presenter: Christopher Brokaw, Master student, Department of Civil and Environmental Engineering, (Adviser: Dr. Amlan Mukherjee)

Abstract: Building information modeling (BIM) is a type of software that can be used to create a 3D model of a construction project that integrates information about the materials and scheduling. This makes it is possible to quickly explore multiple alternate designs and evaluate their performance, as well as plan out the entire project and management strategies. This allows for improved information management and project control when compared to projects designed with 2D drafting software. In this presentation, I will use a hands-on demonstration to explore BIM software and illustrate how stakeholders can use this software to streamline the design process, reduce conflicts, and save money. I will also present an overview of my ongoing research project that, in addition to the above, will explore the benefits of transitioning to BIM software, and will show some of the lessons learned from the early adopters.
