Overview

Analytical studies uncover how structural components affect responses in moment-resisting frames, indicating energy absorption impacts.

Key Points

  • Larger peak displacement occurs in reinforced concrete frames under sequential multi impulses than single ones, especially when the strength is low.
  • Energy dissipation degradation becomes notable in concrete frames under sequential motion when pinching behavior is significant and strength is low.
  • The increase in response period for reinforced concrete frames is significant under pulse-like ground motion and critical pinching conditions.
  • Nonlinear time history analysis shows that the second pulse's most critical period surpasses that of a single pulse as it relates to response accuracy.
