 Many experimental studies have evaluated the in - plane behavior of reinforced concrete frames in order to understand mechanisms that resist progressive collapse . The effects of transverse beams , frames and slabs often are neglected due to their probable complexities . In the present study , an experimental and numerical assessment is performed to investigate the effects of transverse beams on the collapse behavior of reinforced concrete frames . Tests were undertaken on a 3 / 10 - scale reinforced concrete sub - assemblage , consisting of a double - span beam and two end columns within the frame plane connected to a transverse frame at the middle joint . The specimen was placed under a monotonic vertical load to simulate the progressive collapse of the frame . Alternative load paths , mechanism of formation and development of cracks and major resistance mechanisms were compared with a two - dimensional scaled specimen without a transverse beam . The results demonstrate a general enhancement in resistance mechanisms with a considerable emphasis on the flexural capacity of the transverse beam . Additionally , the role of the transverse beam in restraining the rotation of the middle joint was evident , which in turn leads to more ductile behavior . A macro - model was also developed to further investigate progressive collapse in three dimensions . Along with the validated numerical model , a parametric study was undertaken to investigate the effects of the removed column location and beam section details on the progressive collapse behavior
