COMPARATIVE STUDY OF CONCEALED BEAM RC BUILDINGS WITH CONVENTIONAL BEAM RC BUILDINGS FOR GRAVITY LOADS & LATERAL LOADS
Keywords:
Concealed beam, aspect ratio, conventional beamAbstract
The present investigation deals with the comparative behavior of concealed beams in comparison with conventional beams for different grid sizes to have good aesthetic appearance without compromising the strength and serviceability of the building. The different grid sizes adopted by keeping the aspect ratio of 1, to determine the maximum span upto which concealed beam can be used effectively. Aspect ratios are varied to evaluate the effect of concealed beam as secondary beam in slab by laying the beam in shorter and longer span direction. Also the vulnerability of concealed beam building for seismic load is determined by using E-TABS and SAFE software. It is observed that the concealed beam is more effective when used in shorter span of slab and is more vulnerable to lateral
loads therefore they should not be used as main beam in earthquake prone zones
