The partially infilled frames are considered vulnerable in terms of captive column effect for the events of earthquakes. Many reinforced concrete buildings have been affected due to captive column effects. Experimental study has been done to verify the captive column effect and its failure modes for partially infilled frames and the results have been compared with the ones obtained for a bare frame subjected to lateral loading. The results of experimental study have also been compared with some analytical results and the verification of equivalent strut width proposed by one of the authors has been done. From the experimental point of view, it is understandable that due to lateral loading to partially infilled frames, the damage pattern is diagonal and the failure of column occurs at the column-wall joint at the upper side of the wall. It is also seen that for fifty percent partially infilled frames, the stiffness of bare frame is enhanced slightly, however, the failure in the column during lateral loading indicates that the columns are subjected to high shear due to the presence of partial infill.

Seismic Bearing Capacity

“strong beam and weak column”is the main failure states of reinforced concrete frame structure in the earthquake．This paper is the experimental study of the influence on the virtual cross-section bearing capacity on extremity of frame beam in reinforced concrete，which is affected by some element，such as slab reinforcement，the rigidity of orthogonal beam and so on．Exploring the mechanism of slab and frame work together to determine the width of effective flange，which provides references for structural design and engineering application．
