• Abstract:

  The Present Study Investigates The Formulation Of Key Factors For The Modifying Factor Of The Seismic Response Of The RCC Framed Staging Of The Elevated Water Reservoir. The Analysis Revealed That Three Main Factors, Called Reserved Force, Ductility And Redundancy, Affect The Real Value Of The Response Change Factor And Therefore Must Be Taken Into Account When Determining The Change Of The Appropriate Response To Be Used During The Seismic Design Process. The Evaluation Of The Response Modification Factor Is Carried Out Using A Non- Linear Static Pushover Analysis. Pushover Analysis Is An Advanced Tool For Performing Static Nonlinear Analyzes Of Framed Structures. It Is Used To Evaluate Non-linear Behavior And Provides The Sequence And Mechanism For Forming The Plastic Hinge. Here, Displacement-controlled Displacement Analysis Is Used To Apply Seismic Forces In C.G. Of Container. The Thrust Curve, Which Is A Basic Cut Graph Relative To The Displacement Of The Roof, Provides The Effective Capacity Of The Structure In The Non-linear Range. This Could Be Due To The Lack Of Knowledge About The Correct Behavior Of The Tank Support System Due To The Dynamic Effect And Also Due To The Inadequate Geometric Selection Of The Staging. The Objective Of This Study Is To Understand The Behavior Of Different Stages, Under Different Load Conditions And To Reinforce The Conventional Type Of Staging, In Order To Obtain Better Performance During An Earthquake. This Paper Presents A Seismic Analysis Of Elevated Water Tanks Supported In Different Staging Models With Different Tank Storage Capacities. Here We Compare Two Different Support Systems, Such As Radial Reinforcement And Transverse Reinforcement, With The Basic Support System For Various Fluid Level Conditions. Eleven Models Are Used To Calculate The Shearing Of The Base And The Nodal Displacements For Staging With STAAD Pro. After Calculating The Base Cut And The Nodal Displacements Of Eleven Models For Empty And Complete Conditions. Three Different Types Of Staging Systems Were Analyzed.
