Abstract

In RC framed structure, the beam column joint design is crucial. The behaviour of beam column joint is governed by the moment capacity ratio which is generally greater than one. There is a large variation in this value among various codes. The IS: 13920 clearly mentions that the moment capacity ratio at joint to be taken 1.4. Pushover analysis is performed on a frame whose moment capacity ratio (MCR) is increased increased with an increase in column dimensions as well as reinforcements to ensure strong column–weak beam. Its effect on the lateral displacement, base shear, storey drift, ductility and formation of hinges are studied and optimum value of moment capacity ratio is calculated. It is concluded that for better ductility and attaining plastic hinges at end of beams rather than in column, the MCR should not be less than 1.4. To achieve this, increasing the reinforcement in column proves to be more effective rather than increasing column dimensions.
