Researchon concrete box girder (Single & double cells) bridges using finite element method

Abstract

Bridge construction today has achieved a worldwide level of importance. Extension development today has accomplished an overall dimension of significance. Extensions are the key components in any street system and utilization of strengthened support type spans picking up notoriety in scaffold building organization in light of its better security, functionality, economy, stylish appearance and auxiliary effectiveness. By and large for long range Box brace spans are progressively basic proficient. Box support opposes the torsional unbending nature and appropriate for critical bend. For this investigation, four distinctive scaffold supports are viewed as specifically Rectangular Single and Double cell Box Girder (RSBG and RDBG), Trapezoidal Single and Double cell Box Girder (TSBG and TDBG) of ranges 20 m, 30 m, 40m and 50m. Direct Static and Modal Analysis are performed on all the considered extension supports utilizing SAP2000 connect wizard. IRC Class AA Tracked Loading framework is considered for the examination. A near give an account of dynamic Characteristics of all the considered extension braces utilizing SAP2000.Keywords: Stiffness, modal analysis, Linear Static analysis, loading system, Dynamic Characteristics.
