Reinforced concrete (RC) frames have been an indispensable part of the construction industry for several decades because they resist both gravity and lateral loads such that entire structure achieves a certain level performance against seismic as per performance-based design philosophy. The procedures RC often encounter many non-engineering defects, especially in developing countries where quality assurance check is cumbersome usually ignored. Among these presence insufficient rebar splice length can affect structures compromise their integrity. To this aim, research gives new insight into effects inadequate on behavior frames. For that, experimental approach was adopted by using micro-concrete concept it demonstrates simple, cheap, evident method to assess properly designed shake table test conducted study two scaled (1/16 scale): one standard frame other with length. result demonstrated had significant capacity reduction, extremely susceptible loading conditions. Furthermore, crack initiation propagation were at beam-column joints base connections. However, defective frame, altered frame's damage points led collapse location splice. In way, evaluates impact high-risk structural components due defects. This be used spread awareness among workers site engineers who are responsible control on-site circumvent defects associated strength issues.
