Seismic behaviour of non-seismically detailed interior beam-wide column joints; part I : experimental results and observed behavior

Four full-scale reinforced concrete interior beam-wide column joints with nonseismic detailing and limited seismic detailing were designed and tested to investigate the seismic behavior of the joints at Nanyang Technological University, Singapore. In this first part of a two-part paper,* expe...
