• Primarily designed and detailed for gravity loads
• The codes provisions may not be adequate
• Non-ductile detailing of reinforcement, both in columns and
beams which can cause many possible brittle failures.
• Dominated by strong beam-weak column behavior which can
cause soft story mechanism.
• The irregularities of the buildings which make it difficult to
predict the behavior of the buildings when subjected to
earthquake.
• Most of the time, these irregularities make the seismic
performance become worse.
