Research Overview

We are mainly researching structural safety considering various uncertainties and risk potentials in loads and structural systems. Reliability engineering, statistical theory, and digital image analysis studies have been conducted to evaluate structural safety rationally and quantitatively.

Research Subjects

  • 1.Collapse analysis of structures.
  • 2.Seismic performance of concrete-filled steel tube (CFT) column.
  • 3.Statistical study of strong motion properties for seismic design.
  • 4.Seismic safety evaluation for structures.
  • 5.Optical full-field measurements for structural deformation.
  • 6.Finite element analysis of reinforced concrete frame structures.

Introduction:

  • 1.Collapse analysis of building structures Examining column over-design factors that affect the collapse probability of building structures when a large earthquake occurs (Figure 1).
  • 2.Seismic performance of CFT short columns Investigating benchmarks for CFT short columns considering the material and mechanical properties (Figure 2).
  • 3.Seismic safety evaluation for structural buildings Evaluating structural seismic reliability considering the uncertainties of parameters on structural analytical models.
  • 4.Optical full-field measurement of structural deformation Developing an optical measurement method based on image analysis for practical monitoring of deformation of structures with high accuracy (Figure 3).
