Seismic Performance of Flat Slab Buildings Considering P-Delta Effect
Abstract: Flat slab structures are becoming quite popular due to functional and architectural advantages. The flat slab structures are flexible when compared to framed structures as the slab is directly columns. Typically the seismic forces in such a structure are resisted by shear wall systems. Under design seismic conditions the lateral displacements are large and the columns deform along with the lateral load resisting system. Under such conditions the columns are …

Behaviour of Irregular Concrete Buildings under Seismic Forces
Abstract: The study of irregularities in a building is a fundamental parameter controlling the seismic response of buildings. From the past history of earthquakes, it is evident that the use of improper structural configurationswith plan irregularities and soft storeys has decisive effects on the seismic performance of buildings. The buildings with abrupt changes in storey stiffness have uneven lateral force distribution along the height, whichis likely to locally induce stress concentration. …

STUDY OF EFFECT OF SSI ON SEISMIC RESPONSE OF AN IRREGULAR RC STRUCTURE ON SLOPING GROUND AND ITS RESPONSE CONTROL BY USING BRACINGS
Abstract: Structures located on sloping terrain surface are more susceptible to earthquake because of uneven plan and elevation irregularities. Lately, high-rise buildings have been design with various plan and elevation irregularities to elevate their visual aesthetics. In the most of cases, the structural analysis under an earthquake load has been done without considering the effect of soil-structure interaction (SSI), thereby it may not reflect the actual seismic response of the structures. …
