Effect of Vertical Irregularities of RC Framed Structures by Using Non-Linear Static Analysis

Major structural collapses occur when a building is under the action of Dynamic Loads which includes both Earthquake and Wind loads. In these modern days, most of the structures are involved with architectural importance and it is highly impossible to plan with regular shapes. These irregularities are responsible for structural collapse of buildings under the action of dynamic loads. Hence, extensive research is required for achieving ultimate performance even with a poor configuration. In the present work, “Effect Of Vertical Irregularities of RC framed Structures by Using Non-Linear Static Analysis”, considering four types of 10-Storied 3-D frames (i.e., a symmetrical elevation configuration throughout its height and three other frames with unsymmetrical vertical configuration starting from sixth floor, placed at corner, at the center and at edge of the plan respectively) it is focused to study their response using Non-Linear Static Analysis. From the studied results of the analysis of four frames, it is observed that in the regular frame, there is no tensional effect in the frame because of symmetry. The response for vertically irregular buildings is different for the columns which are located in the plane perpendicular to the action of force. This is due to the tensional rotation in the structure.
