ANALISIS STRUKTUR BAWAH (SUBSTRUCTURE) FLY OVER JALAN KI MAJA - RATU DIBALAU KOTA BANDAR LAMPUNG
The substructure of fly over is the structure that located below the superstructures, serves to distribute all the style and the load acting on the top of the building to the ground. The building consists of abutment under the bridge, pillars and foundation. The analysis was performed using three-dimensional analysis taking into account the stresses and deformations that occur in the substructure of fly over, or in this case more familiar with using the principles of finite element method and the type of solid modeling calculations. Finite Element Method (FEM) or usually called Finite Element Analysis (FEA) is a numerical procedure that can be used to resolve the problems in the field of engineering, such as stress analysis on the structure. This method is used on the problems of engineering where the exact solution / analytical solution can not be solved. The essense of the FEM is dividing an object to be analyzed, into smaller sections (finite). These sections are called elements of each element one by the other elements associated with nodai (node). Then built a mathematical equation which becomes the object representation. The process of division of objects into sections called meshing. In this analysis, modeling of solid used is a solid element tetrahordenal and solid hexahedronal using analysis program structure, while analyzed are the abutments and pillars flyover by using a form field, and the two forms have modification the type of gravity modification and cantilever for abutment, and type rigid frame and solid pillars. Results of the analysis showed that the abutment abutment type of gravitational field more optimal than the modified type and a cantilever which value the smallest tensile stresses on the type of initial gravity is equal to 6.212 MPa with the greatest deformation 0.00670 mm x direction. While the analysis of stress and deformation in the third pier type indicates that the pier- • type rigid frame is more stable than the piers of a hammerhead type or solid type, where the value of tensile stress on the pier-type rigid frame is equal to 9.902 MPa by deformation of 0.0801 mm x direction.
