DOI: 10.1080/13632469.2016.1210059
Abstract: This study proposes an “optimal” spectral acceleration-based intensity measure (IM) to assess the collapse capacity of highly inelastic frame structures vulnerable to the P-delta effect. The IM is derived from the geometric mean of the… read more here.

DOI: 10.1080/13632469.2017.1286624
Abstract: ABSTRACT With the consideration of higher modes, an attempt is made to develop a spectral-acceleration-based linear combination-type earthquake intensity measure (IM) for high-rise buildings. The modal mass participation factors are determined to take weighting coefficients.… read more here.
