CHAPTER ACTIVITIES

REGULAR CHAPTER MEETINGS

Kick-off meeting (November 5, 2014)

This was an informational session for prospective members as the student chapter was not active during the last 2 years. During the event the EERI-NCSU student chapter president gave an introduction to earthquake engineering, discussed the objectives of the student chapter, presented the officers, talked about all the activities the EERI has and also briefly introduced the activities planned for the semester.

Seminar: Wavelet-based damage detection methods (November 19, 2014)

NC State University Ph.d. student and EERI student chapter president Diego Aguirre presented his topic of study during his Master of Science studies in the University of Puerto Rico at Mayaguez. Students and

faculty members attended this session which focused on damage detection methods for reinforced concrete structures.

Seminar: Performance limit states of circular RC bridge columns (January 28, 2015)

Dr. Chad Goodnight, who is a former NC State student, presented this seminar, in which based on the results of an experimental program of 30 circular RC well-confined bridge columns, he talked about new strain limits and showed recommended modifications to current design methods.

FRIEDMAN FAMILY VISITING PROFESSIONAL VISIT (April 24, 2015)

As part of the Friedman Family Visiting Professional program, the EERI NC State student chapter was selected to

host Dr. Nathan Gould who is the director and chief of technology for ABS Consulting Advanced Engineering

Division in St. Louis, MO. Dr. Gould is a practicing structural engineer with over 23 years of experience in the

design, construction and rehabilitation of major structures in all regions of the United States.

EERI-NCSU officers gave Dr. Gould a tour to the Constructed Facilities Laboratory (CFL). The objective of this tour

was to show the structural laboratory at NC State University as well as to show the different ongoing research

projects. In the figure below is Dr. Nathan Gould and MS student David Overby explaining his research on high

strength steel for seismic applications.

After the tour to the CFL, EERI officers took Dr. Gould to the different facilities in Centennial campus at NC State

University. Subsequently, officers had lunch with him after which Dr. Gould gave a presentation on

performance based seismic retrofitting. His visit ended with presentations from the officers about their

respective research projects.

Due to the scarce number of data available from

instrumented buildings damaged during an

earthquake, large scale shaking table tests of

civil structures offer an invaluable opportunity

to validate structural health monitoring (SHM)

systems and their applicability to structures

subjected to damaging earthquake loads. Signal

processing techniques, using experimental and

simulated data from detailed non-linear, fiber-

based FE models, was employed to validate

wavelet-based model-free methodologies for

damage detection in reinforced concrete (RC)

structures.

When: Wed., Jan 28th Where: Mann Hall 304 Time: 12:20 PM

Bridge columns are designed as ductile elements which form plastic hinges to dissipate energy in a seismic event. To satisfy the aims of performance based design, levels of damage which interrupt the serviceability of the structure or require more invasive repair techniques must be related to engineering criteria. An experimental program was devised to assess the performance of thirty circular well-confined bridge columns. A key feature of the experiments is the high fidelity strain data obtained using an optical 3D position measurement system. The goal of the experimental program was to investigate the impact of load history and other design variables on the relationship between strain and displacement, performance strain limits, and the spread of plasticity. As a result, new performance strain limits and modifications to the current plastic hinge method are recommended for new design.
