01/2012~12/2013   NEESR: Near Collapse Performance of Existing Reinforced Concrete Frame Buildings
Funded by: National Science Foundation (NSF)
Awarded amount: $539,995
Project location: Western Michigan University
Role: Co-Principle Investigator

This research investigates, characterizes, models, and derives practical procedures for the consequences of column shear-axial failure on the collapse of existing vulnerable RC structures. The project will develop system-level acceptance criteria and analytical tools for near collapse seismic performance of existing non-ductile RC frame structures. Four sets of three-dimensional, geographically distributed hybrid simulations (HS) will be conducted using the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) facility at the University of Illinois at Urbana-Champaign to obtain the response up to collapse of a representative three-dimensional structural system subjected to one-directional and tri-axial seismic ground motions.

10/2010~09/2012    NEESR-CR: NEESsoft: Seismic Risk Reduction for Soft Story Wood frame Buildings

Funded by:
National Science Foundation (NSF)
Awarded amount: $1,236,000
Project location: Western Michigan University
Role: Co-Principle Investigator
NEESsoft project is focused on 1) enabling performance-based seismic retrofit of soft-story wood frame buildings; 2) experimentally validating recently proposed concepts in force-based retrofit of soft-story wood frame buildings, and 3) providing a fundamental understanding of collapse mechanisms in wood frame buildings through a systematic experimental program consisting of three major test types at two NEES equipment sites.

The unified controller platform was packaged to a software framework and the corresponding user’s manual was drafted with both software and hardware integrations and Hybrid simulation implementation details.

02/2002~09/2006      Development of a Unified Control Platform for Real time Dynamic Hybrid Simulation

Funded by: NSF NEES Consortium Operation and Maintenance
Project location: University at Buffalo
Role: Research assistant
Real Time Dynamic Hybrid Simulation (RTDHS) was first proposed for structural engineering to evaluate the seismic performance of structural systems/components by combining the physical test and numerical simulation.  During a hybrid simulation, the whole structure under investigation is divided into two parts. The part being physically constructed and tested is considered as the experimental substructure. The physical test can be conduced using either shake tables or dynamic actuators or both of them depending on the researcher’s interest. The rest part of the structure, named as the computational substructure, is numerically modeled and simulated so the dynamic effect on experimental substructure at the interface is determined and applied by physical loading systems.  The RTDHS is a force-based method and includes the currently used seismic testing methods within a unified formulation developed in this dissertation.
The hardware components necessary for RTDHS were integrated into a unified control platform, which includes Structural and Seismic Testing Controllers; Data Acquisition and Information Streaming and Real Time Hybrid Simulation Controllers. A framework to drive the  RTDHS test was designed and implemented to fulfill the function, such as structure response simulations, interface force calculations and compensations necessary to synchronize all components as well as their imperfect performance.  The test platform developed facilitates not only the local RTDHS test but addresses geographically distributed hybrid simulation as well. Its flexible architecture allows to make improvements without modifying the hardware infrastructure.
While a number of tests were performed in medium scale, a small scale pilot setup including a one story shear model, an actuator and a one directional shake table were constructed for the proof-of-concept of the proposed unified control platform. A three story hybrid simulated structure was tested.  Test results verify the concept of the proposed unified formulation in RTDHS and the feasibility of the corresponding operating platform.

Funded by:
Shanghai Science and Technology Development Foundation
Project location: Tongji University
Role: Research assistant
As fiber joining into concrete, the mechanical behavior of concrete will be changed. The calculating formulas of cracking load, ultimate load, and crack width given by general concrete code for common reinforced concrete beam are not hold properly.  This project studied the bending test on high strength high modulus polyvinyl alcohol (PVA) fiber reinforced concrete beam.  Based on the measured data and cracking behavior, a crack width formula of PVA fiber reinforced concrete beam were proposed.
