Abstract
Finite element method (FEM) is a numerical technique for solving engineering problem and mathematical physics, useful problems with complicated geometries, loading, and material properties where analytical solutions may not be obtained. Some of the complicated problems involving load is a cylindrical reservoir structure where crude oil is stored in a tank farm. This paper demonstrates the use of Finite Element Analysis in above surface cylindrical reservoir engineering structure. The reservoir which has sixteen (16) monitoring station was monitored using reflectorless Total station. This paper is a pilot model and it is hoped to be developed further in two more phases to cover the entire reservoir under study. Only two studs in the North East and South East directions were selected to test the FEM forming a triangular shade (Truss) with three elements. The 2-D horizontal displacement was found to be 0.02 mm, while the vertical displacement was found to be -0.03 mm.
Highlights
The security of civil engineering structures demands periodical monitoring
The investigated deformable object must be treated as a mechanical system, which undergoes deformation according to the laws of continuum mechanics (Chrzanowski et al, 2006). This requires the causative factors of the process and the physical characteristics of the object under investigation to be included in both the design and analysis of the deformation. This is achieved by using deterministic modelling of the load-deformation relationship using finite element method (FEM) (Chrzanowski et al, 2006)
This research is a pilot project for a reservoir with 72.3m diameter and height of 22m surrounded with 16 studs serving as monitoring stations
Summary
The security of civil engineering structures demands periodical monitoring. In many civil structures like bridges, vertical oil storage tanks, tunnels and dams; deformations are the most critical parameters to be monitored. The investigated deformable object must be treated as a mechanical system, which undergoes deformation according to the laws of continuum mechanics (Chrzanowski et al, 2006) This requires the causative factors (loads) of the process and the physical characteristics of the object under investigation to be included in both the design and analysis of the deformation. This is achieved by using deterministic modelling of the load-deformation relationship using finite element method (FEM) (Chrzanowski et al, 2006).
