Research Background<br />

Mechanisms leading to the collapse of existing, pre-seismic code<br />

RC frames are NOT well documented.<br />

Shake table tests are currently being conducted at PEER-UCB to<br />

observe & identify the failure components & load redistribution<br />

processes in RC bridge columns & in RC building frames under<br />

seismic & gravity loading.<br />

Identifying mechanisms causing shear failure in RC columns can<br />

be used to develop performance-based seismic design -<br />

strengthen future & existing structures against earthquake<br />

loading<br />

Column shear failure & its effect on the degradation of axial<br />

capacity in a pre-seismic code RC column is the focus of this<br />

project.
