• Abstract:

  The Best Options For Enhancing India Are Generally Those That Have Experienced Significant Earthquakes In The Past Century. Over Half Of The Country Is Deemed Vulnerable To Destructive Earthquakes. Attention Is Being Paid Nationwide To The Seismic Behaviour Of Existing Structures. On The Other Hand, Bridges Are Crucial Parts Of Any Nation's Transportation System. The Majority Of Indian Bridges Were Inadequately Built To Resist Earthquake And Wind Stresses Due To Outdated Building Regulations. With An Aspect Ratio Of Two To Three, The Design Shear Capabilities For Short Piers Are Found To Be Smaller Than The Equivalent Under Flexural Shear Demand Over Strength Conditions. A Double Decked Bridge Located In Zone V Is Subjected To A Seismic Load, But No Research Or Discussion Has Been Conducted On The Layout And Seismic Performance Of The Double- Decker Bridge Metro Pier. With The Use Of CSi Bridge Software, The Analysis Process Is Later Finished. For The Double-decked Bridge, Calculations Are Made For Bending Moment, Shear Force, Period, And Displacements.
