Analysis of a Structure on Sloping Ground under Seismic Effects

Abstract

The aim of this work is to make a study on seismic behaviour of reinforced concrete framed buildings with columns of unsymmetric plan within on storey. For this study an MS Excel sheet was developed in which 26 cases of varying slope by small increments which can formulate the mode shapes, bending moment, shear force, storey drift, base shear, etc.here we considered 0o,4.5o and 9o sloping ground. Considering different seismic zones II, III, IV and V with different soil types soft, medium and hard type. The results were compared. Using STAAD Pro v8i, 4 reinforced concrete frames on plane ground were modelled. Then the analysis was carried out for gravity as well as seismic loading. Models were created for the above cases when placed on sloped terrain. Comparison for various results like Axial force, shear force, moment stress in columns were done. The reinforcement detailing of all the above 8 models were done using STAAD Pro v8i. All the above mentioned models were modelled with element material. The volume ratio and orientation angles were entered as obtained from STAAD Pro v8i concrete design results. Monotonic loading was applied to the models and results like load displacement hysteresis curve, stress on members, deflected shapes, etc. were extracted. The results show that when a reinforced concrete framed structure is built on a sloping terrain, the short columns tend to fail easily. Shear cracking pattern appeared at the beam column joint of short columns. Long column being more ductile takes up lesser lateral force when compared to the short columns.
